Solution
Chemistry ma’am · 4 steps
Name what each drug does to the body, and the four pairs fall into place one by one.
- Calming drugs. Valium (diazepam) is a benzodiazepine that relieves anxiety and stress. That makes it a tranquilizer, so (a) goes with (iv).
- Pain and hormones. Morphine is a narcotic analgesic used for severe pain, so (b) goes with (iii). Norethindrone is a synthetic progesterone used in birth control pills, an antifertility drug, so (c) goes with (i).
List I What it is List II (a) Valium benzodiazepine, reduces anxiety (iv) Tranquilizer (b) Morphine narcotic, relieves severe pain (iii) Analgesic (c) Norethindrone synthetic progesterone (i) Antifertility drug (d) Vitamin B₁₂ needed to make red blood cells (ii) Pernicious anaemia - Vitamin B12. A lack of vitamin B₁₂ causes pernicious anaemia, so (d) goes with (ii).
- So. The full match is (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii), which is option (d).
The idea to keep. For drug-matching questions, learn one example drug for each class: tranquilizers, analgesics, antifertility drugs, and which vitamin prevents which deficiency disease.
