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.

老师好…这道CR题错选A能求解释一下么？谢谢！

请教唐瑭老师：og上的题，答案是D，选了A。不明白D为什么对，是因为最后一句的Although强调的是前半句吗？although一般强调后半句还是前半句？

老师这道题不知道该怎么解！我是这么算的 6!/3!*3!得出来的结果再乘以2，等于40，但答案是30，不知道是哪里算错了，还是我理解错了，希望老师解答！

老师图片里是作文的标题和我在规定时间内写的东西，您看看我错误找全了吗？找错的思维有没有跳跃？第一段和第二段的论证可以这样写吗？以及我每次都是三十分钟压线写完，字数也不多，请老师给我提一些思维和写作上的建议，谢谢！

老师这道题题目有点看不懂，算不到B选项，不知道是题目理解错了还是公式用错了，求讲解

老师能讲解一下这道题吗？

老师您好，这道题的题目有一点看不懂，请问是什么意思以及为什么选d？

老师您好，我想问一下这道题E为什么有利于支持文中观点？

@英吉老师，我最近在看您的录播逻辑网课，您不推荐我们回读。但是我在日常练习的时候做不到读一遍就能弄懂句间关系，或者读第一遍有时候连句子一起都不太清楚。那我们想要练就读一遍就可以了解句间关系的能力，并且用在考场的话，平时可以怎样练习呢？

老师请问这个“or”应该怎么算？
