We have been waiting here for you since two hours.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. for two hours.
- The error lies in the usage of prepositions 'since' time expressions.
- The preposition "since" is used to indicate a starting point in time, typically with a specific point in the past or an event.
- In contrast, the preposition "for" is used to indicate a duration of time.
- When discussing a period of time, like "two hours," the correct preposition to use is "for."
- 'For' effectively communicates that the action of waiting has been ongoing for a duration of two hours.
Thus, the corrected sentence would be: We have been waiting here for you for two hours.
