1. A newly discovered painting on wooden panel by Michelangelo must have been completed after 1507 but before 1509. It cannot have been painted earlier than 1507 because one of its central figures carries a coin that was not minted until that year. It cannot have been painted after 1509 because it contains a pigment that Michelangelo is known to have abandoned when a cheaper alternative became available in that year. Which of the following is an assumption on which the argument depends?

A No stocks of the abandoned pigment existed after 1509.

B Michelangelo did not work on the painting over the course of several years.

C The coin depicted in the painting was known to general public in 1507.

D The wooden panel on which the painting was executed cannot be tested accurately for age.

E Michelangelo’s painting style did not change between 1507 and 1509.

2. In order to save money, some of Company X’s manufacturing plants converted from oil fuel to natural gas last year, when the cost of oil was more than the cost of natural gas. Because of a sudden, unexpected shortage, however, natural gas now costs more than oil, the price of which has fallen steeply over the past year. The cost of conversion back to oil would more than negate any cost savings in fuel. So Company X’s fuel costs this year will be significantly higher than they were last year. Which of the following is an assumption on which the argument above depends?

A Company X does not have money set aside for the increased costs of fuel.

B The increase in the cost of fuel cannot be offset by reductions in other operating expenses.

C The price of natural gas will never again fall below that of oil.

D The cost of fuel needed by those of Company X’s plants that converted to natural gas is not less than the cost of fuel needed by those plants still using oil.

E The price of oil will not experience a sudden and steep increase.

1.原文逻辑：完成在1509前，因为有使用1509后不再使用的颜料。但是只能说明这幅画是在1509前就开始动手画了。是否在1509后不再画不知道。所以选B

1 assumption:假设A x B
A如果1509年以后有没有存货已经无关因为他在1509年以后就已经不在使用这种颜料了了
B取反，他这幅画一直创作了很多年，有可能持续到1509年以后，削弱结论
2. Assumption: D

1. [Assumption] B --> 取反扩大时间范围削弱果因联系
C A newly discovered painting on wooden panel by Michelangelo = after 1507 but before 1509
P1 a coin after 1507;    P2 pigment x after 1509
2. [Assumption] B ❌ D
P 去年converted from oil fuel to natural gas(cheap) last year
P 今年 gas expensive; The cost of conversion back to oil would > negate any cost savings in fuel
C fuel costs this year will be significantly higher than they were last year
B Offset in other operating expenses  本质上还是cost会增加，对结论没有影响。
D 搬运解析：
(D) 是正确的。作者没有考虑到该公司只有 "部分 "工厂转换为天然气的事实。 那么，有些工厂仍然使用石油，而现在石油更便宜。因此，为了得出该公司将 不得不在燃料上花费更多的结论，作者必须假设已转换的工厂的天然气的额外 成本至少与未转换的工厂的石油成本一样多。
