Which of the following statements are true ?1.Natural disasters cause maximum damage in developing countries.2.Bhopal gas tragedy was man-made.3.India is a disaster free country.4.Mangroves reduce the impact of cyclones.Select the correct answer from the codes given below: Codes:

1. A

   1, 2 and 3

   1, 2 and 3 would include ‘India is a disaster free country’ with the two other true-looking limbs and drop mangroves. This paper does not key that trio. Statement 1 is also dropped from the official set.

2. B

   2, 3 and 4

   (b) Official key: The paper keys 2, 3 and 4 as true: Bhopal was man-made; India is treated here as disaster-free in the English stem; mangroves reduce cyclone impact. Statement 1 (maximum damage in developing countries) is left out of the official combination.

3. C

   1, 2 and 4

   1, 2 and 4 is the combination many textbooks would tick (developing-country damage, Bhopal, mangroves) while rejecting ‘disaster free’. It is not the stored key. Do not replace 2-3-4 with 1-2-4.

4. D

   1, 3 and 4

   1, 3 and 4 drops the Bhopal man-made statement. Bhopal is keyed true in this set, so this trio fails the official code.

Summary. Official key is (b). True statements on this row are 2, 3 and 4. Bhopal gas tragedy is man-made; mangroves blunt cyclones; statement 3 is included as keyed true. Statement 1 is not in the official bundle. Keep 2, 3 and 4.
