Select the most appropriate option to fill in the blank and complete the collocation.
Although she didn't reveal her plans clearly, I had a ________ idea.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. rough.
- The sentence suggests that the speaker did not receive a detailed explanation of the plans, but still managed to form an idea about them.
- "Clear" would suggest that the speaker received a detailed explanation.
- "Concise" would suggest that the explanation was brief and to the point.
- "Complete" would suggest that the speaker received all the necessary information to fully understand the plans, which contradicts the given information that the speaker's idea was rough.
- Therefore, the word that best fits the blank is "rough," which means approximate or not detailed.
Thus, the correct sentence would be:
Although she didn't reveal her plans clearly, I had a rough idea.
The sentence implies that the speaker's understanding of the plans is not clear or precise, but rather a rough estimation.
