Question 1 · Hard
A village has well water with fluoride of 3 mg/L, and many schoolchildren have mottled teeth. No other water source is available. Which measure should the health team recommend?
1. ABoiling all drinking water
2. BFluoride toothpaste for every child
3. CDefluoridation by the Nalgonda technique
4. DExtra chlorination of the well
Show answerHide answer
Answer: C · Defluoridation by the Nalgonda technique
Fluoride above about 1.5 mg/L causes dental and later skeletal fluorosis, so the problem is the water source itself. Where no alternative source exists, the Nalgonda technique removes fluoride by adding alum and lime, followed by flocculation, settling and filtration. Chlorination and boiling do not remove fluoride, and boiling even concentrates it.
- A: Boiling concentrates fluoride as water evaporates.
- B: Fluoride toothpaste only adds to the fluoride load.
- D: Chlorination disinfects but leaves the fluoride unchanged.
Question 2 · Medium

4. DDiscuss the topic freely among themselves before the audience
Show answerHide answer
Answer: B · Each give a short talk with no discussion among themselves
A symposium is a series of short speeches by experts on different aspects of one topic, and the members do not discuss with one another. The chairman sums up and the audience may then ask questions. In a panel discussion, 4-8 experts talk informally among themselves in front of the audience.
- A: Acting out a situation is role play.
- C: Small groups led by a chairman describe a workshop or group discussion.
- D: Free discussion among experts in front of an audience is a panel.

3. CArgemone oil
4. DMetanil yellow
Show answerHide answer
Answer: C · Argemone oil
Epidemic dropsy is caused by sanguinarine in argemone oil mixed into mustard oil. It causes leg oedema, and can lead to heart failure and glaucoma. The suspect oil can be checked with the nitric acid test, and the family must stop using it at once.
- A: Aflatoxin in mouldy grain damages the liver.
- B: Khesari dal causes lathyrism, a spastic paralysis of the legs.
- D: Metanil yellow is a food colour adulterant, not a cause of dropsy.

Ultraviolet B rays in sunlight convert 7-dehydrocholesterol in the skin into vitamin D3. Few Indian foods are rich in vitamin D, so regular sun exposure of the face and arms is the main source. Covered clothing, indoor life and air pollution raise the risk of deficiency.
