(a) The statement given is a false statement. Infact, information regarding a forthcoming storm should be propagated to everyone. This will enable everyone to get prepared for this natural disaster. Everyone will be equipped with all the precautionary measures needed to be taken during the storm.
(b) The statement given is a true statement. This is because the water in the water bodies in which we swim are good conductors of electricity. Also, a wet person is more conductive than a dry person. Due to this, our body inside the water will become very prone to lightning strike. It could cause severe burns or might kill us if lightning falls on our wet body.
(c) No, it is not possible to prevent or control the eruption of a volcano. However, by means of science and technology, it is possible to predict an eruption and take immediate steps for disaster management.
(d) Heavy rains may cause flood in a region. Due to this, food crops, plants etc. of that region are going to get washed away. Also, the land of that region will lose it fertility and would require sometime to regain it. Because of these reasons, the region will be affected by famine. Thus, we can say, heavy rains result in famine.
