Which of the following is a key observation for terrorism indicators?

• A. Unusual activity
• B. Suspicious devices
• C. Secondary explosions
• D. Unusual activity, suspicious devices, or secondary explosions

Answer: (D)

Recognizing terrorism indicators relies on noticing a range of signs rather than a single cue. Unusual activity in an area can signal surveillance, preparation, or abnormal behavior. Suspicious devices or unattended packages present a clear risk and may indicate a threat. The prospect of secondary explosions means an attacker could follow the initial blast with additional blasts. Because any of these signs can appear independently, the most accurate observation includes all of them. In practice, if you observe any of these, heighten awareness, alert authorities, and follow safety protocols to protect yourself and others.
