Zorluk: OrtaSubject-Verb Agreement

In computational linguistics, researchers analyze how digital text corpora evolve over generations. The semantic mapping of obscure dialects—which often relies on machine learning models trained on limited historical texts—______ a unique opportunity to study linguistic drift in real time. By tracing subtle shifts in word usage across decades, scholars can better understand how geographical isolation and cultural exchanges shape modern vocabulary.

Which choice completes the text so that it conforms to the conventions of Standard English?

  1. A
    presenting
  2. B
    present
  3. presentsCevap
  4. D
    have presented

Cevap

The verb 'presents', which is singular and present tense, correctly matches the singular subject 'mapping'.
The singular, present-tense verb 'presents' correctly agrees in number with the singular subject 'the semantic mapping'. The intervening clause ('which often relies on machine learning models...') describes the subject but does not change its number.

Adım Adım Çözüm

1
Identify the subject of the sentence containing the blank.
The subject is the singular noun phrase 'the semantic mapping'.
Subject-verb agreement requires identifying the true subject of the clause, ignoring any intervening descriptive phrases or clauses.
2
Analyze the intervening element between the subject and the verb.
The clause '—which often relies on machine learning models trained on limited historical texts—' is a nonessential modifier containing plural nouns ('dialects', 'models', 'texts').
These plural nouns can distract from the singular subject 'mapping'.
3
Select the verb form that agrees with the singular subject and fits the context.
The singular verb 'presents' correctly agrees with the singular subject 'mapping' and provides a finite verb to complete the clause.
The other options either use plural verb forms or a non-finite participle, violating subject-verb agreement or creating a sentence fragment.
