Read the sentence below. Which present-tense form of the verb 'to provide' correctly completes the sentence to maintain proper subject-verb agreement?
Cevap:The detection of gravitational waves from colliding neutron stars 【provides】 astrophysicists with a new method for measuring the expansion rate of the universe.
Cevap
provides
The correct verb form is the singular present-tense 'provides' because the subject of the sentence is the singular noun 'detection'. The intervening prepositional phrases 'of gravitational waves' and 'from colliding neutron stars' contain plural nouns, but they do not affect the agreement of the main verb with the singular subject.
