Sentence improvement (polarity and logic): evaluate if any correction is required Original sentence: "You need not come unless you want to." Choose the best option; if the sentence is already correct and natural, select "No correction required".

Given data

• Original: “You need not come unless you want to.”

Concept/Approach
The structure “need not … unless …” is idiomatic and logically sound: attendance is unnecessary except in the case where the person desires to come.

Option analysis
No correction required — correct; the original is concise and idiomatic. ✅You don’t need to come unless you want to — also acceptable paraphrase, but test directions typically prefer “No correction required” when the given sentence is already correct.You come only when you want to — changes modality (from permission/necessity to a restrictive rule).You come unless you don’t want to / You needn’t come until you don’t want to — faulty logic/awkward temporal use of “until”.

Common pitfalls

• Confusing unless (if not) with until (up to the time that).

Final Answer
No correction required.
