题目问most weaken。虽然B的证据不一定表明完全是人类导致的,但是在一定程度上给了证据去加强(Nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption.)

ron说过看代词用的对不对有没有ambiguous就看选项中有没有不用代词的选项,如果有,那么就应该选不用代词的那一项
选项e应该是the rest of the 30 inches,the rest+整体
E.g., Here is $100. Buy gas for your trip, and then use the rest of the $100 to buy food.
"”> Note how this works. $100 is the total. The amount you'll have to spend on food is not $100, but $100 minus $(whatever you pay for gas).
balance,rest作主语,谓语用单数,e中应该用balance
over/above是介词,接名词,A后面的sth is 是个句子,错误
C,cause the sea level to rise about 60 feet above its present height,60 feet是名词,作rise的宾语,above its present height作定语,修饰60 feet,超过它目前高度的60尺。
B, cause the sea level to be raised over its height presently about 60 feet, presently修饰raised,引起了海平面现在上升超过它的高度60尺,不是现在上升,是超过现在的高度
