Consider the following statements
I. Nuclear winter is a term that describes the predicted climatic effects of nuclear war.
II. A 2008 study published in the proceeding of the National Academy of Science, USA found that a nuclear weapons exchange between Pakistan and India using their current arsenals could create a near-global ozone hole, triggering human health problems and wreaking environmental havoc for at least a decade.
Which of the statements given above is/are corrcet?

0,21,11,3,6,21,2

keywords: 

{'climatic effects': [0, 0, 1, 0], 'global ozone hole': [0, 0, 1, 0], 'environmental havoc': [0, 0, 1, 0], 'weapons exchange': [0, 0, 1, 0]}

The correct answer is option 3, which states that both statements I and II are correct.

Statement I is true, as nuclear winter is indeed a term used to describe the predicted climatic effects of nuclear war. It is based on the hypothesis that the massive amounts of smoke, dust, and soot generated by a nuclear exchange would block sunlight, leading to a significant drop in temperatures and severe disruptions in climate patterns.

Statement II is also true, as mentioned in a 2008 study published in the proceedings of the National Academy of Science, USA. The study found that a nuclear exchange between Pakistan and India using their current arsenals could lead to the creation of a near-global ozone hole, which could cause human health problems and have severe environmental consequences for at least a decade.

Therefore, both statements correctly describe the potential consequences of a nuclear weapons exchange, making option 3 the correct answer.
