题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

Most European countries offer a variety of programs for assisting
working parents, which include paid maternity and paternity leaves,
financial allowances for families with children, and they subsidize
public nurseries and kindergartens.
这题犹豫在AE选项，首先是which和including的区别，就去看发起者，发起者应该是那个programs，所以就觉得E直接用including不好，A的which给我感觉发起者变了，不是那个countries了，但是后面and后面A多了个they，这个they指的是国家，发起者没变，很多余，E则没有，纠结了一下后我选的A然后就错了

When a polygraph test is judged inconclusive, this is no reflection on the examinee. Rather, such a judgment means that the test has failed to show whether the examinee was truthful or untruthful. Nevertheless, employers will sometimes refuse to hire a job applicant because of an inconclusive polygraph test result.

Which of the following conclusions can most properly be drawn from the information above?
老师， 这道题我选了D，正确答案C。 其实我的理解是：因为说到底是truthful还是untruthful的，是inconclusive的。 我对inconclusive的理解是：非决定性的，不确定的。所以这个测谎的结果可能是错误的。 C选项说的是unfairly。也就是不公平的。感觉有些发散。原文没有提到是否公平。 比下来，觉得C比D好。 麻烦老师讲讲，应该具体怎么理解？ 谢谢。

It can be inferred from the passage that the "scholars" mentioned in line 24 believe which of the following to be true?
老师， 这题我一直没弄懂，毕竟还是一道OG题。正确答案是B，我选的是C。 能否麻烦老师，就这道题，讲讲应该如何infer？ 非常感谢。 我的错题思路如下： 根据问题，我定位到了line 24，把scholar的观点又读了一遍。 也就是Scholoar认为，G 创建了这种意识。并且把后面一句也读了：其实作者认为这种意识是已经存在的，G只是给了它政治表达。 读选项： A) 肯定错 B) G要改变一些态度，使它的活动找到根基。 By Angela -- 虽然是infer，我也知道可以“演绎”。 但原文意思是G 只是政治表达，并没有提到需要什么根基。 我的理解是：已经存在的意识，是不是就是根基？ 即便单看Scholar的观点：这种意识是G创建的。那怎么就infer出来需要改变来找根基呢？ 没有看到任何迹象。 C) 非洲美国人的敏感度，提供给了G政治的基础。 By Angela -- 觉得这个与原文后两句的意识比较接近。 已经存在的意识，提供了G理论的基础。 D) 没有提到G自己的态度。 E) 没提过。

Parasitic wasps lay their eggs directly into the eggs of various host insects in exactly the right numbers for any suitable size of host egg.  If they laid too many eggs in a host egg, the developing wasp larvae would compete with each other to the death for nutrients and space.  If too few eggs were laid, portions of the host egg would decay, killing the wasp larvae.

Paint on a new airliner is usually applied in two stages: first, a coat of primer, and then a top coat. A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat. Using the new process instead of the old process increases the price of a new aircraft considerably.
Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?
我选的E 因为新的可以继续用老的设备 那不就是节约钱了吗
