还有关于CR, 哎呀,我真是问题好多,请楼楼包含。
对于文段里面因果性并不明显,然后选项也比较隐晦的CR。脑子里会经常没有预测方向,然后排掉正确答案,想请教楼楼这种问题老犯错,逻辑思维方面还欠缺什么?或者需要什么策略?比如下面这道Pack2的题目:
A major chemical spill occurred five years ago at Baker’s Beach, the world’s sole nesting ground for Merrick sea turtles, and prevented nearly all the eggs laid that year from hatching. Yet the number of adult female Merricks returning to lay their eggs at Baker’s Beach has actually increased somewhat since five years ago. Clearly, environmentalists’ prediction that the world’s Merrick population would decline as a result of the spill has proven unfounded.
Which of the following, if true, most seriously undermines the argument offered in refutation of the environmentalists’ prediction?
A. The chemical spill five years ago occurred at a time when there were neither Merrick sea turtles nor Merrick sea turtle eggs on Baker’s Beach.
B. Female Merrick sea turtles begin returning to Baker’s Beach to lay their eggs when they are ten years old.
C. Under normal conditions, only a small proportion of hatchling female Merrick sea turtles survive in the ocean until adulthood and return to lay their eggs at Baker’s Beach.
D. Environmental pressures unrelated to the chemical spill have caused a significant decline in the population of one of the several species of sea birds that prey on Merrick sea turtle eggs.
E. After the chemical spill, an environmental group rejected a proposal to increase the Merrick sea turtle population by transferring eggs from Baker’s Beach to nearby beaches that had not been affected by the spill.
答案是B
还有一个小小请求,前面有读到楼楼的关于思考GMAT到底要考什么,想请楼楼能不能就上面的SC OG805和这道CR为例,说说你是怎么思考GMAT到底想考什么?非常感谢
