Question
Mohan is respected / by everyone / because he works /
hardly. The following sentence has been split into four segments. Identify the segment that contains a grammatical error.ÂSolution
The error is in the use of "hardly," which means barely or almost not. The correct word here is "hard," which means with great effort or diligence. The adjective "hard" is appropriate to describe how Mohan works, while "hardly" would imply he works very little or not at all, which changes the intended meaning.
