Unless she doesn’t study French carefully, she cannot get the highest marks in the class.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Unless she studies.
- The phrase "Unless she doesn’t study" is incorrect because "unless" already implies a negative condition. Adding "doesn’t" creates a double negative, which is grammatically incorrect and changes the intended meaning.
- "Unless" is a conjunction used to introduce a conditional clause that indicates something will happen only if the specified condition is not met.
- The condition here is to "study French carefully."
- The correct structure should be: "Unless" + positive condition.
- It's incorrect because "unless" means "if not," so adding "doesn’t" creates confusion.
- Corrected sentence "Unless she studies French carefully, she cannot get the highest marks in the class."
