相交不是不包括相切吗？所以1个点怎么成立呢？

emmmm我觉得D好对啊。。第一段介绍模型，第二段举例有人做出来是inconsistent的，但其实是没太用对，应该要international啥啥的，不就是illustrate its use 讲这个模型应该怎么用吗？？为什么use要翻译为用途而不是使用这个过程/行为呢

老师，我当时排除了A，因为我感觉它质疑的是前提，我目前还是没有想通这个A选项

代数0.04

(a-b)(a+b)=a2-b2

integer

漏看：at least 100
变量相同：
4 percent of the students at the school who study French also study Japanese
10 percent of the students at the school who study Japanese also study French

average sales

（E) "in athletics" is far general and out of discussion. Inhaling pure oxyen doesn't increase muscular reabsorption of oxygen doesn't mean that it is not useful in other athletic areas.

Reasoning: Magu should donate because the donations help Magu increase its sales.
A weakner should be that the donations won't help increase sales.
(D) doesn't point out how "donations benefit little to the community" impact consumers' behaviors or the increase sales. Assuming that people would not buy Magu's products because their donations benefit little to the community is beyond the context.
(E) same problems with D
(B) donations hurt spending in advertisement, thus hurting sales.

选项d和题干内容冲突，题干已经提到亩产减少了，亩产指的是每亩的产量下降了，也就是收成下降了，而D是在用一种很狡猾的方式让人们把植株的数量和产量挂钩，得出产量应该是double 的错误推断。
A是最佳选项，因为影响利润的因素为成本和收入，A将成本这一项解释了。

定语从句不是可以根据最合理的意思，判断修饰谁吗？

1、to another one=individual
2、Almost like clones in their similarity to one another...” That phrase includes the plural pronoun “their”, so it needs to be followed by a plural noun that could reasonably be described as “like clones” in terms of their similarity to each other.
3、“species” can also be plural, but in this case, it’s followed by “is”, and then “its” refers back to “species” later in the sentence. So “species” is definitely singular in this particular sentence.

错选了c。 过去完成式。原句想说 a call was included when drafting. c变成了，a call had been included when adopted. 意思变了。

请问一下并列从句里面的and that其中的that什么时候可以省略什么时候必须保留？谢谢

除forbid外，禁止系动词后面接(from) doing,，如：
prohibit/inhibit/prevent/stop/deter/restrain/ban sb from doing sth，禁止/阻碍/阻止某人做某事，from doing意指禁止某人在某物进行时去沾染它，禁止某人参与某事的进程
forbid似乎是唯一一个表示禁止，后面不接from doing只能接to do的动词 A错误
