A valid syllogism is one in which the conclusion follows logically from the premises. In the given syllogism, the first premise states that all men are mortal. The second premise states that Socrates is a man. From these two premises, we can logically conclude that Socrates is mortal.

A fallacy is an argument that appears to be valid but is actually not. In the given argument, the first premise states that all birds have wings. The second premise states that penguins are birds. From these two premises, we cannot logically conclude that penguins can fly. This is because there are some birds, such as penguins, that do not have the ability to fly.

The converse of a statement is formed by switching the hypothesis and the conclusion. In the given statement, the hypothesis is "it is raining" and the conclusion is "the ground is wet". Therefore, the converse of the statement is "if the ground is wet, then it is raining".

The inverse of a statement is formed by negating both the hypothesis and the conclusion. In the given statement, the hypothesis is "it is raining" and the conclusion is "the ground is wet". Therefore, the inverse of the statement is "if it is not raining, then the ground is not wet".

The contrapositive of a statement is formed by negating both the hypothesis and the conclusion, and then switching them. In the given statement, the hypothesis is "it is raining" and the conclusion is "the ground is wet". Therefore, the contrapositive of the statement is "if the ground is not wet, then it is not raining".
