A more thorough explanation:

An evasive answer is a response to a question that does not directly admit or deny the question. This type of answer is often given by witnesses or defendants in legal cases.

• During a trial, a witness is asked if they saw the defendant commit the crime. Instead of answering yes or no, the witness gives a vague response that avoids the question.
• In a deposition, a defendant is asked about their involvement in a business deal. The defendant gives a long-winded answer that does not directly address the question.

These examples illustrate how an evasive answer can be frustrating for those seeking information. It can also be seen as a failure to answer, which can have consequences in legal proceedings.
