Having learn my lessons
I was very careful
in dealing with him
in front of his room-mate E. No error
Answer is Right!
Answer is Wrong!
The correct answer is: A. Having learn my lessons
The sentence should be: Having learned my lessons, I was very careful in dealing with him in front of his roommate.
The verb “learn” must be in the past participle form, “learned,” to agree with the subject “I.” The preposition “in” is used to indicate a location or position, and the preposition “front” is used to indicate the position of something in front of something else. In this sentence, “in front of his roommate” indicates the location of the speaker in relation to the person being spoken about.
The sentence is grammatically correct and makes sense.
