In the country of Veltria, the past two years' broad economic recession has included a business downturn in the clothing trade, where sales are down by about 7 percent as compared to two years ago. Clothing wholesalers have found, however, that the proportion of credit extended to retailers that was paid off on time fell sharply in the first year of the recession but returned to its prerecession level in the second year. Which of the following, if true, most helps to explain the change between the first and the second year of the recession in the proportion of credit not paid off on time? (A) The total amount of credit extended to retailers by clothing wholesalers increased between the first year of the recession and the second year. (B) Between the first and second years of the recession, clothing retailers in Veltria saw many of their costs, rent and utilities in particular, increase. (C) Of the considerable number of clothing retailers in Veltria who were having financial difficulties before the start of the recession, virtually all were forced to go out of business during its first year. (D) Clothing retailers in Veltria attempted to stimulate sales in the second year of the recession by discounting merchandise. (E) Relatively recession-proof segments of the clothing trade, such as work clothes, did not suffer any decrease in sales during the first year of the recession. 这道题错选了A。 思路如下： 题目问的是为什么在经济不好，衣服卖不动的情况下，第一年零售商还不上钱第二年就能还上了。讲的是零售商还钱的问题。 当时留下的是A,C,D 排除D是因为觉得，即使刺激销售量衣服打折也不能说明能还上钱。可能打折卖1块，纵使家当全卖了也不够。 排除C是因为觉得， 那些本身经济状况就很差的在第一年被淘汰掉以后，剩下的那些没说经济状况如何啊，如果也不咋地，第二年还是得淘汰啊。 A选项当时觉得，即使credit extended，对pay off on time也无太大用处，但最起码跟原文意思接近。所以选了A。

麻烦金帮我解答一下这一题，我的思路是看主语“T的风格和选择”，先不看破折号里面的修饰内容，然后根据主谓一致排除了ACD ，然后看BE，然后就没什么思路，这题是考时态，还是比较？就是关于这个AS AS 我知道的点是它一半用于同级比较，然后根据as 后面的代词去接着判断？

三个因子怎么得出X=a²，请在详细推理一下，不是很懂

老师，这道题根据您的答案，定义应该是1000＝2的9次方乘以X。 但是这样的话这个X就不能是整数了，不符合上面92题的定义呀。 所以没想明白，觉得应该还是1000＝2*2*2*5*5*5。选E

从条件1看，p也可以等于32呀！ 32是2的5次方，所以的质数可以写成1和2，同时为了满足＞1的条件。只是只能是2，所以不能准确推理呀 只有当两个条件合起来，p是33或35时才能满足。因此应该选C不是A

请数学老师说下思路

张老师你好，这道题目我不太懂C为什么错。因为这道题目我的方法是直接定位到黄色highlight部分，然后看这句话的前后句子，因为前面一句话看着好像比较无关，我就重点看了后面一句话，说了这些guilds的women是有legal和economic的privileges ，所以我一看C就对了。然后正确答案是A，不太懂怎么才能选对，也不理解c为什么是错的，虽然A看了这句话也对，但是考试的时候做这种题目我为了节约时间通常都是只看highlight附近的句子的，求指教！然后这类型的题目大概难度系数是多少？谢谢

老师，请问这倒是题目的考点是什么！C选项中哪里错了？我理解的是with it的it指带不清楚，求老师指教！谢谢！

which of the following about the insects from which animals acquire carotenoids？老师您好怎么判断这句话是倒装呢？我理解的意思就是昆虫从动物获取carotenoids

麻烦金老师帮我解决下这一道题，此句的核心语意是A这个人开始翻译 I 这个作品，后面一个同位语从句进一步解释这个工作花了多少年和S对它的评价。根绝a work that and that 这个平行结构先排出了 A E ,然后C 答案的 had taken 和 began 时间点上是冲突的，先开始了，才有完成的事，所以had taken 过去完成时在这里用法不正确。对比B D ，文学批评家S 宣称最好的译品；文学批评家S宣称它做为最好的译品。。我觉得后者更好，尽管有一瞬间也纠结了IT的指代问题，麻烦老师帮我辨析一下，正确答案B“S宣称最好的作品in。。”感觉话没说完整。

请问老师，这里的reduced by 150,是减到150，还是剪了150
