Question

A council of ecologists in Hawaii have conclude that much of the currently uncontrolled invasive species on the island chain were arriving in the holds of cargo ships.

• A. have concluded
• B. has concluded
• C. have concluded
• D. concluded
• E. has concluded

Hint:

Ensure that the subject and verb agree in number. If the subject is singular, use the singular verb form.

Answer 1

The Correct Option is B

Step 1: Subject-verb agreement.
The subject "a council" is singular, so the correct verb form should be "has" instead of "have."
Step 2: Review the options.
- (A) Incorrect; the subject "council" is singular and should match with the verb "has."
- (B) Correct; "has concluded" agrees with the singular subject "council."
- (C) Identical to (A) and also incorrect.
- (D) "Concluded" is the correct verb tense, but the subject-verb agreement is wrong.
- (E) Identical to (B) but incorrect in structure.
Conclusion:
The correct answer is (B), as it ensures subject-verb agreement.
