这道题正确答案是 B， 我一直觉得是D, 不是特别明白 B 答案为什么 说as effectively as sea snakes can? One such adaptation is the closer proximity of the terrestrial snake's heart to its head, which helps to ensure circulation to the brain, regardless of the snake's orientation in space. The heart of sea snakes can be located near the middle of the body, a position that minimizes the work entailed in circulating blood to both extremities. In arboreal snakes, however, which dwell in trees and often assume a vertical posture, the average distance from the heart to the head can be as little as 15 percent of overall body length. Such a location requires that blood circulated to the tail of the snake travel a greater distance back to the heart, a problem solved by another adaptation. 20. It can be inferred from the passage that which of the following is true of species of terrestrial snakes that often need to assume a vertical posture? (A) They are more likely to be susceptible to circulatory failure in vertical postures than are sea snakes. (B) Their hearts are less likely to be located at the midpoint of their bodies than is the case with sea snakes. (c) they cannot counteract the pooling of blood in lower regions of their bodies as effectively as sea snakes can. (d) the blood pressure at their midpoint decreases significantly when they are titled with their heads up.

老师请问这个问题如何解答

请Tina老师讲解。这个题目问法第一次遇到，说下面哪个不是削弱。这种问法相当于在问哪个是支持或者无关吗？做题时觉得AB都是与原文逻辑无关选项。CDE都在解释一个城市与另一个相比，心脏相关手术的成本因素不同，感觉都与原文相关，但是也不是削弱。这个题目感觉摸不着方向

请王文静老师解答。我理的逻辑链：因为热的地方容易缺水，且全球变暖让温度更高，所以肾结石病会增加。我选的E，说天气热的地方结石病多，冷的地方少。A选项给我感觉是因果倒置，病多的地方，天气热，反了。请老师讲解这个题的正确解题思路，并且指出我的错误在哪，如何避免

C选项的It为什么是指代不清呀

金老师好，当时看B觉得to conquer 的发起者是登山者，不应是hazards，但是根据including觉得是hazards包括这几个事，E从语法上成了amateur including了，这个Ving找动作发起者的规则这里不适用吗？

请老师讲一下思路

请老师讲下第七题思路。我的理解是条件1可以判断，想要成立则xy的个位数应该是5或者0，这样次方之后依然是5或者0，即xy的个位应该相等，所以答案是No。老师，我是错误理解题意了吗？

徐老师讲下第六题，是用捆绑法吗？做这种题特别没有思路，怎么办？

求问解题思路
