Cevap

The singular verb 'is' correctly completes the sentence.
The sentence subject is 'Every student', which is singular and requires the singular verb 'is'. Intervening plural nouns within prepositional phrases do not change the subject from singular to plural.

Adım Adım Çözüm

1
Identify the true subject of the sentence.
The subject is 'Every student', which is grammatically singular.
Nouns qualified by 'every' or 'each' always take a singular verb.
2
Analyze intervening phrases.
The phrase 'in the science laboratories' is a prepositional phrase acting as a modifier.
The object of a preposition ('laboratories') does not control the agreement of the main verb.
3
Select the verb form that provides proper singular concord.
'is' is the appropriate singular present-tense verb.
A singular head subject requires a singular verb.
