What does underreporting mean?

• A. It means presenting all details in full.
• B. It is the phenomenon of not fully presenting the extent, magnitude, or frequency of an issue.
• C. It refers to exaggerating the problem.
• D. It indicates the claim is well-supported.

Answer: (B)

Underreporting is the phenomenon of not fully presenting the extent, magnitude, or frequency of an issue. It happens when data or information about how widespread or serious a problem really is are incomplete, hidden, or understated. This matters because decisions depend on accurate measurements, and underreporting can mask the true scale, leading to insufficient responses or resources.

Presenting all details in full would be comprehensive reporting, not underreporting. Exaggerating the problem is overreporting, not underreporting. A claim being well-supported relates to the quality of evidence, not how completely the issue is disclosed.
