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.

作文，感觉这个有点难找，有些地方不知道驳了算不算抬杠，请英吉老师指点一下改善一下我的思路，谢谢！

May老师，我这个题解出来是纯算数做出来，感觉有点麻烦，有没有比较简便的方法可以做这个题呢？ 谢谢老师

金栩竹老师，这道题为什么要选择to doing 呢？to do 与to doing有哪些区别呢？感觉没怎么见过to doing 的形式。

Tina老师，这个E的those of 没有问题吗？这个指代的是哪里呢？ B哪里有问题呢？C的错误是在of嘛？

Tina老师，这个come在这里是谁的谓语呀，前面efforts 的谓语不是aimed吗？这里也只有一个连词，连词后的account不也是谓语么。

【张慧雯】老师 不好意思，不好意思🤦‍♀️ 刚刚手抖打错字了。 就是这道题，我刚重新看了一会，文章思路大致有了谱，但是这个题要问什么，自己怎么定位到原文这里，不太懂了。其他题中，像这样的，让你找最不可能的，排除东西做的题，也都不太懂🤦‍♀️

请英吉老师看一下我这个作文的思路有无什么不足，打问号的是我不太确定的，谢谢！
