Zorluk: OrtaSubject-Verb Agreement

Museum conservators face unique challenges when protecting organic artifacts. In museum curation, the long-term preservation of historic oil paintings on delicate wood panels, which are highly sensitive to sudden fluctuations in relative humidity, ________ a combination of stable microclimates and precise environmental monitoring to prevent the wood from warping. Conservators must therefore rely on advanced climate control systems to maintain stable conditions.

Cevap

demands
The singular verb 'demands' correctly agrees with the singular subject of the sentence, 'preservation.' Intervening descriptive elements such as 'of historic oil paintings on delicate wood panels' do not affect the singular status of the subject.

Adım Adım Çözüm

1
Locate the subject of the clause containing the blank.
The subject is 'preservation,' which is a singular noun.
Finding the head noun of the subject phrase is necessary to determine if a singular or plural verb is required.
2
Identify and disregard any intervening phrases or clauses between the subject and the verb.
The prepositional phrase 'of historic oil paintings on delicate wood panels' and the relative clause 'which are highly sensitive to sudden fluctuations in relative humidity' both modify the subject but do not change its grammatical number.
Intervening phrases containing plural nouns often distract from the true singular subject.
3
Select the verb option that is singular and fits the grammatical structure of the sentence.
'demands' is the correct singular present-tense verb form. 'demand' and 'have demanded' are plural, and 'demanding' is a non-finite verb.
A singular subject must be paired with a singular verb to maintain subject-verb agreement.
