Match the items given in Column A with the most appropriate ones in Column B and REWRITE the correct matching pairs:
Column A: (i) Cranial nerves (ii) Leydig cells (iii) Acetylcholine (iv) Spinal nerves (v) Sneezing Column B: — Testosterone — Natural reflex — 12 pairs — Prolactin — Neurotransmitter — 18 pairs — 31 pairs — Conditioned reflex
Topic: Matching — nerves, hormones and reflexes
Answer
(i) Cranial nerves — 12 pairs (ii) Leydig cells — Testosterone (iii) Acetylcholine — Neurotransmitter (iv) Spinal nerves — 31 pairs (v) Sneezing — Natural reflex
Column B has EIGHT options for FIVE items, so three are distractors. Do not force a match.
THE THREE TRAPS, each paired with its correct partner: "18 pairs" against "12 pairs" and "31 pairs" — the real figures are 12 pairs of CRANIAL nerves (from the brain) and 31 pairs of SPINAL nerves. 18 belongs to neither. "Prolactin" against "Testosterone" — both are hormones, but Leydig cells secrete TESTOSTERONE. Prolactin comes from the anterior pituitary and stimulates milk production. "Conditioned reflex" against "Natural reflex" — SNEEZING is inborn and therefore NATURAL. A conditioned reflex is LEARNT, such as salivating at the sight of food.
STRATEGY: do the certain pairs first and let elimination settle the rest.
