The detectives are reviewing the Great Donut Heist of 2024. Select ALL the questions that are grammatically correct for their investigation board.
The correct answers are Has the main suspect confessed? and Have the witnesses spoken to the chief?
The auxiliary verb must agree with the subject!
"The security guard" is singular, so it needs "Has" (Has the security guard checked...?).
"The fingerprints" is plural, so it needs "Have" (Have the fingerprints been analyzed?).
