CAT Exam 2015 preparation 4

Fossil-fuel companies have lobbied hard – and often successfully – against effective climate policies. But a recent report by the environmental research group CDP revealed that at least 29 major companies, including five major oil producers, are basing their internal planning on the assumption that such policies – specifically, a government-mandated carbon price – will be a reality as soon as 2020. The question now is whether oil-producing countries’ governments and citizens share this expectation. World leaders are ostensibly committed to keeping the increase in average global temperature below 2°C relative to pre-industrial levels – the threshold beyond which the most catastrophic effects of global warming would be triggered. Indeed, they endorsed the limit at the 2009 Copenhagen Climate Change Conference, and again in Cancún the following year.

In the light of the above passage, which of the following is the most relevant question that the author ought to answer?

OPTIONS
	1)	Why does the success of fossil fuel companies’ planning depend on the expectations of oil-producing countries’ governments and their citizens’?
	2)	Will the oil producers’ lobby divest funds from fossil fuels?
	3)	What could be a reason behind the global leaders’ avowed commitment to keeping the increase in average global temperature below 2°C relative to pre-industrial levels?
	4)	Is the report of the environmental research group CDP credibl       John is working on an electronic LED board that has 480 LEDs numbered 1 - 480 and placed in ascending order on the board. He programs the board such that all the LEDs are initially switched off. At the end of one second, all the LEDs are switched on and at the end of two seconds, all the LEDs at even places invert their logic state i.e. they get switched off if they are on and get switched on if they are off. After three seconds, all the LEDs numbered 3, 6, 9, … invert their logic state. This pattern continues at the end of each subsequent second. How many LEDs are on just after 3 minutes and 45 seconds have passed? OPTIONS     1) 169   2) 231   3) 249   4) 311
