The loud noise had a big ______ on my concentration. Fill in the blank with the correct word meaning 'result.'

• A. consequence
• B. reason
• C. effect
• D. trend

Answer: (C)

Choosing a word that means the result or outcome of a cause is what this sentence is after. The loud noise is the cause, and it changes how well I can concentrate, so we need a noun that names that change. “Effect” fits naturally because we say “to have an effect on something” to describe that kind of influence. So the sentence reads smoothly: “The loud noise had a big effect on my concentration.”

Reason isn’t about the result but the cause or justification, so it doesn’t fit as the outcome. Consequence can work in some contexts, but in everyday phrasing it sounds heavier and isn’t the most natural choice here. Trend refers to a pattern over time and isn’t about a sudden impact.
