Crime-detection technology is primarily used to what?

• A. Identify weapons, drugs, or persons
• B. Track financial activity
• C. Monitor internet usage
• D. Manage payroll

Answer: (A)

The main idea being tested is what crime-detection technology is designed to uncover in the field. These tools are meant to reveal contraband, weapons, drugs, or people connected to illegal activity, so officers can intervene, secure evidence, or verify identities. That’s why identifying weapons, drugs, or persons is the best description of its primary use. The other options don’t fit because tracking financial activity, monitoring internet usage, or managing payroll are not about detecting crime or locating illicit items or suspects; they relate to financial audits, cyber surveillance in a different context, or administrative HR tasks, which fall outside the core purpose of crime-detection technology.
