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.

请问may老师此题思路

想问一下c那个蓝色的解释是什么意思啊

b为什么错了？c中to offer，不就没有谓语了吗

想问一下这道题的a和b，enduring那块不是很懂

想问一下e，car那个sell不应该是被动形式吗

想问一下这个题什么意思？

he 要和人一定要对应吗

语法：想问一下这道题考点是什么？ 我选b是因为我当时觉得bake alone 然后花时间更多的这两个说的是一件事，花时间多是bake alone的结果，所以没用and

语法！b当中so不是连词，不会被当成两个句子吗？ d哪里错了呢

希望英吉老师批改一下寂静作文。
