1)All the offices on the 9th floor have wall-to-wall carpeting. 2)No wall-to-wall carpeting is pink. 3)None of the offices on the 9th floor has pink wall-to-wall carpeting. If the first two statements are true, the third statement is

Statement 1: All 9th floor offices have wall-to-wall carpeting. Statement 2: No wall-to-wall carpeting is pink. This means the carpeting on the 9th floor cannot be pink. Statement 3: None of the 9th floor offices has pink wall-to-wall carpeting. This is logically valid - since the carpeting exists and isn't pink, statement 3 follows necessarily. This tests categorical syllogistic reasoning.
