Question

Choose the word or phrase that best completes the sentence.

__________ they had been waiting in line all night, I was sure they'd get tickets.

• A. as though
• B. because of
• C. since
• D. until

Answer 1

Answer: (C)

since

A preposition is a word which comes before a noun or a pronoun and establishes a relationship between the elements of a clause or words. Option C)since is correct as it is used to express a starting point of time and the duration until now. The other options are wrong as the sentence doesn't indicate the use of expressing a reason, a cause, and until doesn't indicate a starting point of time. The correct answer is C)since.
