Proposition C is in standard form because it has the subject and predicate terms in the correct order (No recessions are times of economic expansion) and the quantifier is a universal negative ("No").

The other options either make incorrect assumptions or exclude possible scenarios.

Question 13

Not every concert pianist is famous.

Accepted Answer

The statement implies that there are concert pianists who are not famous, but it does not exclude the possibility that some are famous. Option A implies that all concert pianists are famous, which is contradicted by the statement. Option B implies that no concert pianist is famous, which is also contradicted by the statement. Option D is essentially the same as option C but uses a double negative, which can be confusing. Option E is not relevant to the statement as it is talking about a different category of people (famous people, not concert pianists). Therefore, the best choice is C.

A child peered through the window.

Accepted Answer

The statement "A child peered through the window" implies that at least one child peered through the window. However, it does not indicate that all children peered through the window or that some did not. Therefore, options A, C, and D can be eliminated. Option E is incorrect as it suggests that only children identical to the child mentioned in the statement peered through the window, which is not supported by the information given. The best choice is B, which accurately states that at least some children are people who peered through the window.
