Surveillance is done through only certain phases of a terrorist attack.

• A. True
• B. Not specified
• C. False
• D. Sometimes

Answer: (C)

Surveillance is often an ongoing part of a terrorist operation, not confined to a fixed subset of stages. In practice, attackers gather information before deciding on targets, continue observing security and response patterns as they prepare and execute, and may monitor outcomes afterward to learn for future plans. Because surveillance can occur before, during, and after an operation, saying it happens only in certain phases isn’t accurate.

That’s why the statement is false. If someone says it’s true, they’re implying surveillance is limited to specific moments, which doesn’t reflect how attackers typically collect data across the whole process. “Sometimes” or “not specified” are less precise than recognizing that surveillance can span multiple phases, making false the idea that it’s restricted to particular stages.
