Question

1. which of the following answer choices shows the negation of the statement below? statement: frank has a sister. frank does not have a sister. frank has a brother. frank has a sister or a brother. frank does not have any siblings.

Explanation:

The negation of a statement "Frank has a sister" should directly contradict the original statement. The original statement claims Frank has at least one sister. Its negation is that Frank does not have a sister. The other options either introduce a different relation (brother), a disjunction (sister or brother), or a stronger claim (no siblings) which is not the direct negation of just having a sister.

Answer:

A. Frank does not have a sister.
