The guard's stated reason for the children’s presence was that they were what?

• A. Their cover
• B. Their own kids
• C. Their cousins
• D. Their chaperones

Answer: (A)

Using people as cover means presenting a harmless front to hide the real purpose. Here, the guard's claim that the children were there to serve as that front explains why their presence would be justified in a way that avoids triggering suspicion. The children act as a plausible, innocent scene that makes the guard’s activities seem routine rather than suspicious. The other possibilities describe who the children are (their own kids, cousins, or chaperones) but don’t explain why their presence would be used to mask the guard’s true intent. The idea of a cover is to misdirect attention, and that’s exactly what this stated reason accomplishes.
