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.
