  2. yieldsCevap
  3. C

  4. D
    yielding

Cevap

The correct answer is the singular verb 'yields', which properly agrees with the singular subject 'detection'.
The singular verb 'yields' correctly agrees with the singular subject 'detection'. Intervening prepositional phrases and parentheticals like 'along with...' do not change the grammatical number of the subject.

Adım Adım Çözüm

1
Identify the subject of the sentence containing the blank.
The grammatical subject of the clause is 'detection'.
Subject-verb agreement requires identifying the true subject, ignoring intervening modifying phrases.
2
Determine the number of the grammatical subject.
The noun 'detection' is singular.
Plural nouns inside prepositional phrases (like 'waves' or 'mergers') or introduced by non-conjunction connectors (like 'along with') do not affect the singular nature of the main subject.
3
Select the verb choice that matches the subject in number and fits the tense of the sentence.
The singular verb 'yields' correctly matches the singular subject 'detection'.
The sentence requires a singular finite verb to complete the clause correctly.
