  1. helpedCevap
  2. B
    helps
  3. C
    will help
  4. D
    is helping

Cevap

helped
The correct option is the simple past tense verb 'helped'. The sentence describes historical actions completed in the past ('published'). To maintain parallel structure and temporal consistency within the compound predicate ('published... and [blank]'), the verb in the blank must also be in the simple past tense.

Adım Adım Çözüm

1
Identify the subject and grammatical structure of the clause.
The subject is 'Britton', and the blank is part of a compound predicate linked by 'and' to the verb 'published'.
This establishes that the blank verb must align grammatically and temporally with 'published'.
2
Determine the correct tense for the verb based on the temporal context.
Since 'published' is in the simple past tense and describes completed actions in the late nineteenth century, the missing verb must also be in the simple past tense.
Maintaining consistent past tense is necessary to describe completed actions in Britton's lifetime.
