Question

Instructions [109-110]: The following questions have sentences which are incomplete. Pick up one phrase / clause from the options given, that will complete the sentence logically.

To ensure success in a difficult task _________

• A. one needs to be persistent
• B. persistence is needed
• C. you need a person of persistence
• D. persistence is what one needs

Hint:

Pick the phrase that states the needed quality directly, using the correct noun form.

Answer 1

The Correct Option is B

Look at each option as if you read the whole sentence out loud, and ask which one sounds like something a careful writer would actually say.

1. One needs to be persistent: correct grammar, but it introduces "one" as a new subject and turns the sentence into a statement about people in general rather than about the quality needed.
2. Persistence is needed: short, direct, and grammatically sound, it names exactly the quality the task demands without extra words.
3. You need a person of persistence: confusing, since the sentence is about succeeding at a task yourself, not about needing another person.
4. Persistence is what one needs: grammatically fine but wordier than necessary, the cleft construction adds emphasis that the plain sentence does not call for.

The simplest, clearest and most natural completion is "persistence is needed", so option B is the answer.
