QUESTION 1 OF 20

Why is the 2nd trimester considered riskier for MTP compared to the 1st trimester?

Answer Review

1 Why is the 2nd trimester considered riskier for MTP compared to the 1st trimester?

A The foetus is smaller and easier to remove.

B The physiological and biological complexity of the pregnancy increases.

C 1st trimester MTPs are performed by quacks.

D There is no statutory ban in the 2nd trimester.

💡 Short Explanation

Fetal size and placental attachment increase significantly after the first trimester. Surgical risks to the mother rise as gestation progresses. The procedure becomes biologically more demanding.

✅ Correct Answer Explanation

The safety of MTP is heavily dependent on the duration of gestation. In the first trimester, the fetus is small and the pregnancy is less integrated with the maternal systemic circulation, making the procedure relatively simple. As pregnancy progresses into the second trimester, physiological changes and structural development make intervention significantly more complex and hazardous for the mother.

❓ Why Other Options Are Incorrect

Option A → Incorrect, as the fetus is larger in the 2nd trimester, not smaller.
Option C → Unprofessional practices are not the medical reason for the categorization of safety.
Option D → The legal framework has specific requirements for the 2nd trimester, making this statement irrelevant to medical risk.

🎯 Strategy

Used: Contextual/Tonal Matching

Application: Identifying that "riskier" correlates with "physiological complexity" in medical texts.

Final Logic: Increased complexity = Increased medical risk.

🧠 Memory Trick

More time = More risk.

2 A woman is 10 weeks pregnant. Based on safety guidelines in the sources, an MTP at this stage would be:

A Highly risky

B Relatively safe

C Impossible to perform

D Only possible after 24 weeks

💡 Short Explanation

The first trimester is defined as the safest period for MTP. 10 weeks falls squarely within the first 12 weeks. Early medical/surgical intervention carries minimal risk.

✅ Correct Answer Explanation

MTP procedures are considered "relatively safe" when conducted during the first trimester (up to 12 weeks). Since 10 weeks is within this timeframe, the clinical risk is low compared to later stages of pregnancy.

❓ Why Other Options Are Incorrect

Option A → Incorrect; it is considered safe, not highly risky.
Option C → Medical termination is standard practice at this stage.
Option D → This contradicts the established legal and medical timeframe.

🎯 Strategy

Used: Substitution

Application: Substituting "10 weeks" with "first trimester" makes the classification as "relatively safe" immediate.

Final Logic: 10 weeks < 12 weeks (the safe zone).

🧠 Memory Trick

10 is within 12.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: First trimester safety –

3 MTP is often used to get rid of unwanted pregnancies. Which of the following is NOT a reason mentioned for such a need?

A Failure of contraceptive used during coitus

B Casual unprotected intercourse

C Pregnancy resulting from rapes

D To balance the number of male and female children in a family

💡 Short Explanation

MTP is for medical/health-related grounds. Sex-selective termination is illegal and unethical. The other three are accepted clinical/circumstantial grounds.

✅ Correct Answer Explanation

MTP is legally permitted for health reasons, contraceptive failure, or non-consensual intercourse (rape). Sex-selective termination (choosing the sex of the child) is not a legal ground for MTP; in fact, it is a criminal offense under the PCPNDT Act.

❓ Why Other Options Are Incorrect

Option A → Legitimate ground for MTP.
Option B → Legitimate ground (unwanted pregnancy).
Option C → Legitimate ground for termination.

🎯 Strategy

Used: Odd One Out

Application: Identify the illegal/unethical practice from the list of clinical/circumstantial grounds.

Final Logic: Sex selection $\neq$ MTP ground.

🧠 Memory Trick

Sex-selection = Illegal.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Abortion Grounds –

4 Grounds for termination include:
(i) Risk of grave injury to the mental health of the pregnant woman.
(ii) A child being born with serious physical handicaps.

A (i) is true, (ii) is false

B (ii) is true, (i) is false

C Both are true

D Both are false

💡 Short Explanation

Maternal mental health is a core legal ground. Fetal handicaps/abnormalities are a core legal ground.

✅ Correct Answer Explanation

The MTP Act lists both maternal health (physical or mental) and fetal health (serious abnormalities) as valid grounds for the termination of a pregnancy. Both statements (i) and (ii) accurately reflect these legal provisions.

❓ Why Other Options Are Incorrect

Options A, B, D → These deny valid legal provisions stated in the textbook.

🎯 Strategy

Used: Contextual/Tonal Matching

Application: Validating both statements against the MTP Act's definition of "grounds for termination."

Final Logic: MTP = Maternal health OR Fetal health risk.

🧠 Memory Trick

Mother's Mind + Baby's Body.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Abortion Grounds –

5 If a pregnancy has lasted 18 weeks, how many registered medical practitioners must provide an opinion in "good faith" for a termination to be legal?

A One

B Two

C Three

D None, it is illegal after 12 weeks

💡 Short Explanation

Up to 12 weeks: 1 RMP. 12 to 24 weeks: 2 RMPs. 18 weeks is between 12 and 24.

✅ Correct Answer Explanation

According to the MTP (Amendment) Act 2017, for pregnancies between 12 and 24 weeks, the opinion of two Registered Medical Practitioners (RMPs) is required to ensure that the termination is conducted safely and on legal medical grounds.

❓ Why Other Options Are Incorrect

Option A → Only sufficient for the first 12 weeks.
Option C → Not required by law.
Option D → Incorrect; termination is legal up to 24 weeks under specific conditions.

🎯 Strategy

Used: Substitution

Application: Applying the rule: 12-24 weeks = 2 RMPs.

Final Logic: 18 weeks is inside the 12-24 week range.

🧠 Memory Trick

12-24 = 2 Doctors.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: MTP Act 2017 –

6 Match the legal requirement with the pregnancy duration under the 2017 Act:

List-I	List-II
1. < 12 weeks	i. 2 RMPs opinion
2. 12–24 weeks	ii. Not specifically detailed for routine termination
3. > 24 weeks	iii. 1 RMP opinion
4. 0–24 weeks	iv. Overall range for considered grounds

A 1-(iii), 2-(i), 3-(ii), 4-(iv)

B 1-(i), 2-(iii), 3-(ii), 4-(iv)

C 1-(iii), 2-(i), 3-(iv), 4-(ii)

D 1-(ii), 2-(i), 3-(iii), 4-(iv)

💡 Short Explanation

< 12 weeks requires 1 RMP opinion. 12–24 weeks requires 2 RMP opinions. > 24 weeks is not specifically detailed for routine termination. 0–24 weeks represents the overall range for considered grounds.

✅ Correct Answer Explanation

The legal requirements are matched as follows: (1) < 12 weeks → 1 RMP opinion (iii). (2) 12–24 weeks → 2 RMP opinions (i). (3) > 24 weeks → Not specifically detailed for routine termination (ii). (4) 0–24 weeks → Overall range for considered grounds (iv). Therefore, the correct matching is 1-(iii), 2-(i), 3-(ii), 4-(iv), corresponding to Option A.

❓ Why Other Options Are Incorrect

Option B incorrectly swaps the requirements for < 12 weeks and 12–24 weeks.
Option C incorrectly matches > 24 weeks with the overall legal range.
Option D incorrectly assigns < 12 weeks to "Not specifically detailed for routine termination."

🎯 Strategy

Used: Option Grouping

Application: Match the most distinctive legal requirement first: 12–24 weeks → 2 RMP opinions (2-i). Then pair < 12 weeks → 1 RMP opinion (1-iii).

Final Logic: These fixed legal thresholds uniquely identify Option A.

🧠 Memory Trick

1 before 12, 2 after 12.

7 Amniocentesis analyzes fetal cells and dissolved substances to determine:

A The future height of the child

B Fetal survivability and genetic health

C The mother's nutritional status

D The exact date of birth

💡 Short Explanation

Amniocentesis checks for chromosomal disorders. It assesses the health of the fetus. It is not used for non-medical predictors (height/date).

✅ Correct Answer Explanation

Amniocentesis is a diagnostic procedure used to screen for genetic abnormalities (e.g., Down syndrome) and assess fetal health and survivability. It does not provide information about adult physical traits or nutritional levels of the mother.

❓ Why Other Options Are Incorrect

Option A → Height is not determined by amniocentesis.
Option C → Nutritional status is measured through maternal blood tests.
Option D → Due dates are estimated via ultrasound (LMP/Crown-rump length).

🎯 Strategy

Used: Elimination

Application: Filter out non-genetic/medical goals.

Final Logic: Genetic test = Fetal health evaluation.

🧠 Memory Trick

Amnio = Genetic Health.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Amniocentesis Use –

8 Which of the following genetic disorders can be detected using the dissolved substances and cells in amniotic fluid?

A Sickle-cell anemia

B Common cold

C Amoebiasis

D Malaria

💡 Short Explanation

Amniocentesis is for genetic/chromosomal disorders. Sickle-cell anemia is a genetic disorder. The others (Cold, Amoebiasis, Malaria) are infectious.

✅ Correct Answer Explanation

Amniocentesis analyzes fetal genetic material. Sickle-cell anemia is caused by a gene mutation, which is detectable via this procedure. The other options are caused by pathogens (viruses/parasites).

❓ Why Other Options Are Incorrect

Option B → Viral infection.
Option C → Protozoan infection.
Option D → Protozoan infection.

🎯 Strategy

Used: Odd One Out

Application: Differentiate between infectious diseases and genetic disorders.

Final Logic: Genetic test = Genetic disorder detection.

🧠 Memory Trick

Amnio = Genetic (Sickle-cell).

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Amniocentesis Use –

9 The "dangerous trend" mentioned in the sources involves combining which two actions?

A Amniocentesis for genetic testing followed by immunization

B Amniocentesis for sex determination followed by MTP if the foetus is female

C MTP for maternal health followed by blood transfusion

D Early detection of STIs followed by counseling

💡 Short Explanation

Misuse of amniocentesis for sex-determination is a social evil. Combining this with MTP leads to female foeticide. This is the "dangerous trend" mentioned in the text.

✅ Correct Answer Explanation

The textbook highlights that amniocentesis, originally meant to detect genetic diseases, is often misused to determine the sex of the fetus. This knowledge is then used to terminate female fetuses, a practice that has caused a demographic imbalance and constitutes a grave social concern.

❓ Why Other Options Are Incorrect

Option A → Immunization is not linked to this issue.
Option C → MTP for maternal health is a legal, life-saving act.
Option D → This is a healthy, desirable practice.

🎯 Strategy

Used: Contextual/Tonal Matching

Application: Link the concept of "dangerous trend" specifically to the issue of sex-selective abortion.

Final Logic: Sex determination + MTP = Female foeticide.

🧠 Memory Trick

Trend = Female Foeticide.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Amniocentesis Misuse –

10 Which of the following is NOT a reason the government legalized MTP with strict conditions?

A To avoid its misuse

B To check indiscriminate female foeticides

C To encourage illegal abortions by quacks

D To provide a legal framework for health-related terminations

💡 Short Explanation

MTP legalization aims to curb quackery and unsafe abortions. It does not "encourage" illegal practices. It provides a safe, legal pathway.

✅ Correct Answer Explanation

The legalization of MTP was intended to provide a safe, regulated environment for women who need the procedure for medical or legal reasons. It is specifically designed to eliminate the need for dangerous, illegal abortions performed by quacks.

❓ Why Other Options Are Incorrect

Option A → Legalization regulates and monitors the procedure to prevent misuse.
Option B → Legalization is a tool to control the illegal practice of sex-selective foeticide.
Option D → Legal frameworks are established to protect maternal health.

🎯 Strategy

Used: Extreme Word Filter

Application: The word "encourage" contradicts the intent of a regulatory medical law.

Final Logic: Laws are meant to stop illegal practices, not encourage them.

🧠 Memory Trick

Legal = Safety, NOT Quacks.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Amniocentesis Misuse/MTP Act –

11 Why are STIs also called Reproductive Tract Infections (RTI)?

A Because they only affect the lungs.

B Because they primarily infect the organs of the reproductive tract.

C Because they are only transmitted via contaminated food.

D Because they are non-infectious.

💡 Short Explanation

The pathogens of STIs target the reproductive anatomy. "RTI" (Reproductive Tract Infection) describes the anatomical site of the infection. STIs are definitely infectious.

✅ Correct Answer Explanation

STIs are infections spread via sexual contact. Since the primary organs affected by these pathogens (e.g., urethra, cervix, uterus) are part of the reproductive system, the clinical term "Reproductive Tract Infection" (RTI) is used to categorize them.

❓ Why Other Options Are Incorrect

Option A → STIs are not respiratory infections.
Option C → They are transmitted via sexual contact, not food.
Option D → They are highly infectious.

🎯 Strategy

Used: Substitution

Application: Define "Reproductive Tract" as the target site for the infection.

Final Logic: Site of infection = Reproductive Tract.

🧠 Memory Trick

RTI = Reproductive Tract.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: STI Definitions –

12 Regarding STIs:
(i) All persons are vulnerable to these infections.
(ii) Incidences are reported to be very high among the 15-24 year age group.

A (i) is true, (ii) is false

B (ii) is true, (i) is false

C Both are true

D Neither is true

💡 Short Explanation

STIs do not discriminate; everyone is at risk. Youth (15-24) are statistically the most vulnerable demographic according to health reporting. Both facts are standard NCERT data points.

✅ Correct Answer Explanation

Public health data confirms that no individual is immune to STIs (vulnerability). Furthermore, epidemiological studies consistently report that the 15-24 age group has the highest incidence rates, largely due to social and behavioral factors.

❓ Why Other Options Are Incorrect

Options A, B, D → Incorrect as both foundational facts provided in the text are true.

🎯 Strategy

Used: Contextual/Tonal Matching

Application: Confirm both statements align with textbook facts.

Final Logic: Everyone is at risk, and youth are most affected.

🧠 Memory Trick

All = Vulnerable; 15-24 = High Risk.

13 Match the infection with its characteristic:

List-I	List-II
Gonorrhoea	(i) Common STI
Syphilis	(ii) Common STI
Genital Herpes	(iii) Non-curable STI
HIV	(iv) Most dangerous STI

A 1-(i), 2-(ii), 3-(iii), 4-(iv)

B 1-(iv), 2-(iii), 3-(ii), 4-(i)

C 1-(ii), 2-(i), 3-(iii), 4-(iv)

D 1-(i), 2-(ii), 3-(iv), 4-(iii)

💡 Short Explanation

Gonorrhoea/Syphilis are standard STIs. Herpes is a lifelong (non-curable) viral infection. HIV is highlighted as the most dangerous.

✅ Correct Answer Explanation

(1-i) Gonorrhoea is a common STI. (2-ii) Syphilis is a common STI. (3-iii) Genital Herpes cannot be cured permanently. (4-iv) HIV is defined as the most dangerous STI due to AIDS. Option A is the only correct match.

❓ Why Other Options Are Incorrect

Options B, C, D → Incorrect pairings.

🎯 Strategy

Used: Option Grouping

Application: Match "HIV" with "Most dangerous" (4-iv) and "Herpes" with "Non-curable" (3-iii). Only A fits this.

Final Logic: Direct categorical matching.

🧠 Memory Trick

HIV = Danger; Herpes = Permanent.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Common Infections –

14 Which of the following is NOT a common STI mentioned in the source list?

A Trichomoniasis

B Hepatitis-B

C Haemophilia

D Chlamydiasis

💡 Short Explanation

Haemophilia is a genetic, blood-clotting disorder. It is not an infection or an STI. The others are infectious conditions.

✅ Correct Answer Explanation

Haemophilia is a hereditary genetic condition where blood fails to clot properly. It is not an infection and is therefore not an STI.

❓ Why Other Options Are Incorrect

Option A, B, D → These are infectious diseases listed as STIs in the chapter.

🎯 Strategy

Used: Odd One Out

Application: Distinguish between an "Infection" (STI) and a "Genetic disorder" (Haemophilia).

Final Logic: Haemophilia $\neq$ Infection.

🧠 Memory Trick

Haemophilia = Genetic, not Infection.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Common Infections –

15 Arrange the following based on the complexity of transmission mentioned in the sources (Direct contact to indirect/fetal):
(i) Transfusion of blood
(ii) Sharing surgical instruments
(iii) Infected mother to foetus

A (i)-(ii)-(iii)

B (iii)-(ii)-(i)

C (ii)-(i)-(iii)

D (i)-(iii)-(ii)

💡 Short Explanation

Blood transfusion involves high-volume contact. Sharing instruments is an indirect contact route. Mother-to-fetus is a unique physiological (vertical) transmission.

✅ Correct Answer Explanation

This order represents a progression from direct fluid exchange (transfusion) to contaminated equipment (sharing instruments) to biological transmission (mother-to-fetus). Option A matches the logical, structured listing of transmission vectors.

❓ Why Other Options Are Incorrect

Options B, C, D → Incorrect sequences that do not follow the biological complexity hierarchy.

🎯 Strategy

Used: Option Grouping

Application: Identify the logic of "Direct (Transfusion) to Indirect (Instruments) to Biological/Fetal (Mother to fetus)."

Final Logic: Transfusion → Instruments → Mother-to-fetus.

🧠 Memory Trick

Blood → Tool → Baby.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: HIV and AIDS –

16 HIV is categorized as the most dangerous infection because:

A It is easily cured with antibiotics.

B It is not completely curable and leads to AIDS.

C It only affects the elderly.

D It is transmitted through casual touch.

💡 Short Explanation

HIV causes AIDS, which is terminal without care. There is no total cure. It is not casual, and it affects all ages.

✅ Correct Answer Explanation

HIV is considered the "most dangerous" because of the lack of a permanent cure and the devastating progression to AIDS, which systematically destroys the host's immune system, leading to death.

❓ Why Other Options Are Incorrect

Option A → HIV is viral, not bacterial; antibiotics are ineffective.
Option C → It affects individuals of all ages.
Option D → It is not transmitted by casual touch.

🎯 Strategy

Used: Contextual/Tonal Matching

Application: Identify the severity of HIV compared to other infections.

Final Logic: HIV = AIDS = Fatal/Incurable.

🧠 Memory Trick

HIV = AIDS = Fatal.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: HIV/AIDS –

17 According to the sources:
(i) Genital herpes is completely curable if detected early.
(ii) Most STIs are curable except for a specific few like Hepatitis-B and HIV.

A (i) is correct, (ii) is incorrect

B (ii) is correct, (i) is incorrect

C Both are correct

D Both are incorrect

💡 Short Explanation

Genital herpes is NOT curable. Hep-B, Herpes, and HIV are the non-curable "few." Statement (i) is false; Statement (ii) is true.

✅ Correct Answer Explanation

Statement (i) is incorrect because Genital herpes is chronic and not fully curable. Statement (ii) is correct because it identifies that while most STIs (e.g., Syphilis, Gonorrhoea) are curable, exceptions like HIV, Hep-B, and Herpes exist.

❓ Why Other Options Are Incorrect

Options A, C, D → Incorrect as (i) is false.

🎯 Strategy

Used: Elimination

Application: Recall which STIs are curable vs. chronic.

Final Logic: Herpes = Not curable.

🧠 Memory Trick

Herpes = Forever.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Non-Curable STIs –

A (ii)-(iii)-(i)

B (i)-(ii)-(iii)

C (iii)-(ii)-(i)

D (ii)-(i)-(iii)

💡 Short Explanation

Visit a professional (ii). Get tested/diagnosed (iii). Finish treatment (i).

✅ Correct Answer Explanation

Proper clinical management requires visiting a qualified expert, confirming the infection, and then complying with the full treatment regimen. Option A follows the standard medical procedure for STI management.

❓ Why Other Options Are Incorrect

Options B, C, D → Incorrect logical sequence (e.g., treating before diagnosis).

🎯 Strategy

Used: Option Grouping

Application: Follow the medical workflow: Doctor → Diagnosis → Treatment.

Final Logic: Doctor → Diagnosis → Treatment.

🧠 Memory Trick

See Doc → Test → Treat.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Management of STIs –

📄 Passage

"Absence or less significant symptoms in the early stages of infection and the social stigma attached to the STIs, deter the infected persons from going for timely detection and proper treatment. This could lead to complications later, which include pelvic inflammatory diseases (PID), abortions, still births, ectopic pregnancies, infertility or even cancer of the reproductive tract."

What is a significant deterrent for people seeking timely treatment for STIs?

A High cost of medicine

B Social stigma

C Lack of doctors

D Desire for complications

💡 Short Explanation

The passage explicitly mentions "social stigma." Stigma makes people hide the infection. Hiding leads to delayed detection/complications.

✅ Correct Answer Explanation

The textbook passage highlights that social stigma is a primary barrier deterring infected individuals from seeking medical help, which leads to late-stage complications.

❓ Why Other Options Are Incorrect

Option A, C → Not the primary deterrents identified in the passage.

Option D → Incorrect; people do not desire complications.

🎯 Strategy

Used: Contextual/Tonal Matching

Application: Match "deterrent" to "social stigma" as described in the text.

Final Logic: Stigma = Barrier to treatment.

🧠 Memory Trick

Stigma = Silence.

📚 Class XII – Biology – Chapter: Reproductive Health – Topic: Early Symptoms –

📄 Passage

Which of the following is a potential late-stage complication of untreated STIs?

A Improved fertility

B Pelvic inflammatory diseases (PID)

C Increased immunity

D Better reproductive health

💡 Short Explanation

Untreated STIs travel up the reproductive tract. They cause PID, cancer, infertility, and ectopic pregnancies. PID is a classic late-stage complication.

✅ Correct Answer Explanation

Untreated STIs can lead to serious sequelae, including Pelvic Inflammatory Disease (PID), which is a common and severe late-stage complication resulting from the spread of infection to the upper reproductive organs.

❓ Why Other Options Are Incorrect

Option A, C, D → STIs decrease reproductive health, cause infertility, and compromise overall health; they do not improve it.

🎯 Strategy

Used: Elimination

Application: Filter out positive outcomes (A, C, D) as they contradict the nature of a "complication."

Final Logic: Untreated = Infection spread = PID.

🧠 Memory Trick

Untreated = PID/Cancer.
