12. Sorely on the basis of choice B, you cannot exclude the possibility that an extraordinary large number of meteorites unequally fell on a geological region that has a lower rate of destructive geophysical process. So, you cannot sure which reason finally contribute the present abundance of impact caters. From choice C, you can know that, initially, meteorites have been evenly scattered over earth's surface and thus have left generally an equal number of impact caters all over earth. Under this cricumstance, a lower rate of destructive geophysical process becomes the only reason for the fact that, there are quite a larger number of caters in some region while there are fewer in others.
15. This question actually exhibits the strict logical obsession in LSAT vividly. First, pay attention to the words " it is almost impossible". These words tell you that almost all of people mentioned in the article use right hand. Coupled with what the second person said, the conclusion seems inevitable that people's handedness is overwhelmingly influenced by social pressures. Therefore, genetic predisposition cannot be a contributing factor. PLease dont argue with me it sounds impossible in the actual situation. In here, we should deduct every conculsion only from the content of the article.
19. The key in this question is to find out the precise correlation between tree rings and tree age. Choice B only tells you that the pattern of tree rings in the P valley is disctinctive with that of trees in other valley. But it does not show you overtly that those tree rings can represent the age of tree. Choice C sets up such a correlation. |
