An epic is a work of art or legend conveying heroic deeds. Therefore, presumably what is meant to be remembered almost as an epic is the family legend relating to the digging of Chicago's subway tunnels in the early 1900s.

D: “are chiseled from …centuries ago” is incorrect. “were chiseled” must be used instead of “are chiseled” for past tense.

c选项为什么不可以理解bring和continue并列，没有看懂bring的主语是谁，风不可以带来干燥的weather吗

mortality rate = death rate

C. Correct. This statement provides an alternative reason that the number of violations for Azura Airlines would have increased. That is, if the AB conducted more extensive and more rigorous inspections this year, then it is very likely that the number of violations found by the AB would increase. In other words, if more points are tested or existing tests are made stricter, then the increase in rigor of the testing would presumably lead to an increase in violations.

Note that the banker's conclusion is quite strong: The law will soon entirely cease to serve its intended purpose. The only reason to believe that the law would entirely cease to serve its … purpose would be: (1) if circumstances led to the complete disappearance of banks that do exist in specific communities; (2) if somehow circumstances caused investment in impoverished local communities to fail to revitalize those communities.

A. Correct. This claim tells us that garbage containing large quantities of paper and cardboard burns at such a high temperature that a portion of the dioxins in the garbage is destroyed. If so, then reducing quantities of paper and cardboard in burned garbage might in fact increase dioxin pollution, not reduce it, despite the fact that paper and cardboard packaging contains dioxins.

A. Correct. This choice is the most closely analogous to the spokesperson's strategy: the doctor uses an objective test to show the factual claims of the patient to be false.

this argument assumes that the world market price for wheat is fixed and would not be affected by introducing Suriland's wheat supply. That is, it is possible that the world market price per bushel for wheat might decline as a result of an increase in the wheat supply available on that market

接着根据这个变动不超过50%的规律求出最后一天的closing price

当这个change是第一天的增加50%才是最后一天的closing price
所以：最后一天closing price最大值为：20(1+50%)=30
当这个change是第一天的减少50%才是最后一天的closing price
所以：最后一天closing price最小值为：6.67(1-50%)=3.34
因此最后一天的closing price范围是（3.34，30）

A选项3不在这个范围。错误。

解答：设第一天的closing price为F，
当这个change是第一天的增加50%才是第二天的closing price
所以：F(1+50%)=10
F=6.67
当这个change是第一天的减少50%才是第二天的closing price
所以：F(1-50%)=10
F=20
因此第一天的closing price范围是（6.67，20）

题意：上个月的股票价格每天都在变动。变动规律是：
第一天的closing price跟上个月任意一天的closing price的变动不超过50%
如果上个月第二天的closing price是$10,
问下面哪个选项不可能是上个月最后一天的closing price。

分析：因为题目给出第二天的closing price，
而且说第一天的closing price跟任何一天的closing price差别都不超过50%
(这里50%的变动，又有可能是增加50%或者减少50%）
所以我们可以求出第一天的closing price范围。
然后再根据第一天的closing price跟最后一天的price差别都不超过50%来求出最后一天的closing price范围。

出来混迟早是要还的~~~~~😭

设：总rolls 为R, 总成本为300， 平均每个roll的成本为300/R
当天卖出总量的4/5，即4R/5，每个售价：(300/R)*(1+50%)=450/R，
当天收入为：4R/5*450/R=360
第二天卖出剩下的，即：R/5，每个售价：(450/R)*(1-20%)=360/R
第二天收入为：R/5*360/R=72
这批rolls的总收入为：360+72=432
profit：432-300=132
