Which statement about Grandpa's history with the Miami Police Department is true?

• A. He has a checkered history with the Miami Police Department.
• B. He is a member of the Miami Police Department.
• C. He has no history with the police.
• D. He works as a private investigator.

Answer: (A)

Understanding what "history with the Miami Police Department" means is key here. A checkered history signals a mix of encounters—some ordinary or even positive, but also several troublesome or controversial incidents—that create a complicated relationship with the police, not a clean, straightforward one. If the text describes Grandpa as having had various past run-ins or notable past interactions with the department, that aligns with a checkered history and fits the true statement. The other ideas imply a current role or a lack of any contact at all, or assign him a different job, which wouldn’t match a description of past interactions. So, the statement about a checkered history best reflects the described background.
