Identify the part of the sentence that contains a grammatical error.
A. The company has been B. experiencing a lot of C. problems since D. the last two years.
Show answer & explanation
Correct answer: C
Explanation
The error in the sentence is the use of the word "since" with a duration of time ("the last two years"). "Since" should be used with a specific point in time (e.g., "since 2024" or "since last week"). For a duration of time, preposition "for" should be used instead (e.g., "for the last two years").
