SSC CHSL 2025 PYQ — Question 43

Analyze each option:
1) People who read more have a better vocabulary.
This is a correlation—people who read more often possess a better vocabulary, but in every instance, reading more does not directly *cause* a better vocabulary; other factors, such as education and environment, may also contribute.
2) Exercise leads to weight loss.
This is generally a cause-and-effect relationship—under certain circumstances, exercise can directly cause weight loss.
3) Smoking causes cancer.
This is a cause-and-effect relationship—smoking is a proven cause of certain types of cancer.
4) A virus causes the flu.
This is a cause-and-effect relationship—the flu is directly caused by the influenza virus.
Only (1) represents a correlation that lacks a proven, direct cause-and-effect relationship.
Therefore, the correct answer is option (1).
