1.his team detect sound from trucks, motorcycles, chain saws
2.her team detect sounds from trucks, motorcycles, chain saws
3.his team detect sounds from truck, motorcycle, chain saw
4.his team detects sounds from trucks, motorcycles, chain saws
5.No correction required
Correct Answer : 4
Solution :
In the emboldened phrase, the verb 'detect' [third person plural] does not agree with its subject 'team' [singular] and thus the verb must be changed to 'detects' [singular].
The only option with this correction is option (d) and thus all other options are eliminated.
Hence, the correct answer is option (d).
Subject-Verb Agreement: Matching up singular or plural subjects with singular or plural forms of a verb is part of the process called agreement. This can be understood better by the examples given: - "She likes cooking." [singular subject and verb] -- "They like to cook vegetables." [plural subject and verb]
