Question

The students have been practicing for the concert since three weeks, and in that time have improved considerably.

Choose the option that indicates the error in the sentence.

• A. Have been
• B. Since
• C. And
• D. Have
• E. No error

Answer 1

Answer: (B)

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 B) Since is the correct option as three weeks indicates the use of for. The other options are wrong as have and have been indicate tense correctly and 'and' is a conjunction. The given sentence has only one error, i.e. since. Since is used to indicate a duration from the starting time of something , not to indicate just a duration. The correct answer is B) Since.
