SSC GD 2026 PYQ — Question 61

Correct Answer

To disrupt, foil, or cause problems to a plan, activity, or project

Explanation

The idiom "throw a wrench in the works" (also frequently expressed as "throw a spanner in the works" in British English) originates from industrial factories. If a heavy metal tool like a wrench were literally thrown into moving machinery gears, it would instantly jam the gears, stop production, and cause a major disruption. Metaphorically, it means to sabotage, ruin, or completely interfere with the smooth progress of a plan or project.

The other options are incorrect. Having a severe effect on one's feelings relates more to phrases like "a stab to the heart" or "gut-wrenched." The options mentioning tricking a newcomer or physically pulling someone violently are literal traps that incorrectly use the dictionary definitions of "tool" or "wrenching."

Key Points

Idioms that mention mechanical systems, gears, or wheels (like throw a wrench in the works, throw a monkey wrench, or gum up the works) almost always mean to disrupt order, cause a sudden breakdown, or halt an ongoing process.
