Zorluk: OrtaEnd-of-Sentence Punctuation

Read the passage below. Which punctuation mark must be placed in the blank to correctly terminate the first sentence?

Cevap:Many historians have investigated the clandestine operations at Bletchley Park during World War II. For instance, did the Allied command truly expect Alan Turing to crack the complex German cipher codes within a few months【?】 Turing's revolutionary Bombe machine exceeded all expectations and shortened the war by years.

Cevap

A question mark is the correct punctuation mark to terminate the sentence.
A question mark is the only grammatically correct option because the sentence preceding the blank ('For instance, did the Allied command...') is a direct question, as indicated by the subject-verb inversion ('did the Allied command...').

Adım Adım Çözüm

1
Analyze the structure of the clause preceding the blank.
The clause 'For instance, did the Allied command truly expect Alan Turing to crack the complex German cipher codes within a few months' begins with the auxiliary verb 'did' followed by the subject 'the Allied command'.
Identifying the subject-verb inversion helps determine if the clause functions as a direct question.
2
Determine the sentence type of the clause.
The clause is a direct question because it inquires about the expectations of the Allied command.
Direct questions must be terminated with a question mark to indicate the interrogative tone and structure.
3
Select the appropriate end-of-sentence punctuation mark.
A question mark is required to correctly terminate this interrogative sentence before the next independent clause begins with a capitalized letter.
Using a period or a comma would create a grammatical error and misrepresent the sentence structure.

Anahtar Kavram

Direct questions must be terminated with a question mark rather than a period or comma.
