Select the word segment that substitutes (replaces) the bracketed word segment correctly and completes the sentence meaningfully.
After the teacher chose groups, John and Sara (was selected as partners for project), yet Sarah did most of the work.

Correct option is B

The correct substitution of the bracketed words is (b) were selected as partners for a project.
Explanation: The subject here is “John and Sara”, which is plural, and the sentence is in the past tense. Therefore, the correct passive voice construction is were selected. Also, the noun “partners” is plural and requires “a” before the singular “project” but not before plural “partners”. Hence, (b) is grammatically and contextually correct.
Grammatical rule used:
· In passive voice with past events and plural subjects, we use: were + past participle (V3).
· Articles should agree in number with the noun they precede.
Example: The students were selected as members of the committee.
Information Booster:
· "Has selected" and "have selected" are active voice forms.
· "Had selected" is past perfect but active, so incorrect in passive structure here.
· Always match tense, voice, and subject-verb agreement carefully in replacements.
