In the question below, a passage is given followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the following suggested courses of actions logically follow(s) for pursuing. Passage: Greenland's vast ice sheet may have melted beyond the point of return - a new research suggests. No matter how quickly the world cuts emissions that are heating the climate by using existing legislations, the ice is likely to disappear. However, researchers say that cutting climate-heating emissions could still slow the rate of ice loss. Courses of action: I. Global leaders must come together and bring about a legislation to cut down emissions. II. UNFCCC, the entity tasked with supporting the global response to the threat of climate change, must order a more detailed study on the subject to identify the dangers and suggest remedies. III. “Life on mars” mission must be expedited, and all human beings must be transported to Mars as life will not be able to sustain on Earth. Correct Answer Only II follows. Course of action I is not effective as there are already legislations in place to cut down upon climate-heating emissions, but the problem is that they are not adhered to effectively. Hence, instead of bringing about fresh legislation, strict implementation of existing legislation must be ensured. So, Course of action I does not follow. Course of action II follows because what we have here is just one research report by a university. Also, the report (at least as per our passage) is silent on the effects it will cause on various parts of Earth and exact remedial measures (what is suggested here is a crude measure that cutting climate-heating emissions could still slow the rate of ice loss). We need to know the exact details regarding the two and hence further study is warranted. So, Course of action II follows. Course of action III is an extreme and impractical step. Life might still be possible on Earth with remedial measures. Moreover, it is impractical to transport ALL HUMAN BEINGS to Mars. So, Course of action III does not follow. Hence, only II follows.
