如果是一个assumption题，感觉B是对的

m-5=n(n-1)，判断n(n-1)为偶数，odd-5=偶数，可以得出m=odd

条件一：x^2+y^2>z^2，可知不等式两边都大于0，将两边同时平方，不等号的方向不变。得到：x^4+y^4+2(x^2)(y^2)>z^4，因为2(x^2)(y^2)是大于0的，所以条件一不能推出x^4+y^4>z^4
举例子：6，8，9

曼哈顿讲平行那章说，linking verbs are parallelism markers. To read is to feel

我觉得E有点废话的意思。。。。。说了most，又不是all，肯定有考虑到个别人的问题啊

枚举推理！！［答案要提到样本：大多数员工］
纠结在DE
D提到了样本员工，但是E在讲工作月份，未提到样本

看清楚问题

题目说的是新口味会不会提高利润。E探讨的是品牌忠诚的问题，忠实于其他品牌的消费者不会因为新口味而来买这个牌子，但这个牌子的消费者和那些没有brand loyalty 的消费者 不知道会不会选新口味

我开始以为CIn order to offer more flexible schedules to their workers, several businesses in the office building will soon be expanding their hours.
是expending hours的话会叫员工早点来上班，其实不是这样。

划线后还有一个as

a is wrong because of the participle 'placing', which wrongly indicates that this trend is already placing more women in leadership positions.
c is wrong because the relative pronoun 'which' is placed in a position where it must refer to 'women'. this is wrong for 2 different reasons: (a) 'which' can't refer to people, and (b) according to the sentence, women don't place themselves in leadership positions; the trend does.

change in meaning: the correct meaning is what appears in the original sentence, namely, that the failure to honor promises WAS the deceptive business practice. choice e, with its use of 'because', implies that the failure to keep promises LED TO (other) deceptive business practices.

Even though it was not illegal for the bank to share its customers' personal and financial information with an outside marketing company in return for a commission on sales, the state's attorney general accused the bank of engaging in deceptive business practices by failing to honor its promise to its customers to keep records private.

a, this is an ongoing or cumulative trend, continuing into the present from some designated starting point
b, this is a fundamental truth

注意C选项：表示原因的词如because of后面要跟核心词！！分别是drugs和doctors。在逻辑上，原因应该是“药物变贵”和“医生开处方”这两件事，而不是药和医生这两个名词［又是物／事的问题］

it、they的指代
平行问题

只有三者平行或者两个完整的句子间的and前才应该加逗号

after initiating the nation's most comprehensive and aggressive antismoking program→ 主语:California

伴随所表达的因果是一种自然而然的因果，例如：
Jack kicked the post, feeling pain.

where修饰地点，要是具体名词
in place of是连词，且没有转折意思
