Question
NEET 2022 (paraphrased): Regarding reaching the age of adolescence, which of the following statements is correct? (a) adolescence refers to voice change, body hair, breast development (b) secondary sexual characters is characterised by 10 to 19 years approximately (c) menstrual cycle — about 28 days, controlled by estrogen and progesterone (d) endocrine glands has no role in reaching the age of adolescence
Solution — Step by Step
This option swaps the definitions. adolescence is actually 10 to 19 years approximately, not what (a) claims. So (a) is out.
Similarly, secondary sexual characters means voice change, body hair, breast development. Option (b) is mismatched. Out.
This one reads correctly: menstrual cycle — about 28 days, controlled by estrogen and progesterone. Match with NCERT wording confirms it.
endocrine glands — pituitary master gland regulates others — plays a real role in reaching the age of adolescence, so option (d) is factually wrong.
Correct answer: (c) menstrual cycle — about 28 days, controlled by estrogen and progesterone.
Why This Works
NEET PYQs on reaching the age of adolescence rely on definition swapping. The examiner takes two correct facts and pairs them with the wrong terms. If you know each fact cold, the MCQ dissolves in 20 seconds.
Alternative Method
For definition-swap MCQs, don’t read all four options first. Read option (a), decide true/false, then (b), and so on. This prevents confusion between similar-looking options.
NEET reuses the same fact set every 2–3 years with different distractors. Master the four NCERT facts on reaching the age of adolescence listed here and you’ll handle almost any MCQ on this chapter.
Common Mistake
Students second-guess themselves when they see a familiar option listed as “wrong” in the stem. Trust the elimination — if you know the definition, stick with it.
Keep a one-page sheet of definitions for every NEET chapter. Revise only that sheet in the last 48 hours before the exam.
