　　2.The correct answer is A

　　The error in this sentence occurs at (A), where awkward phrasing and an unnecessary pronoun create a comma splice. The entire phrase “It depends on” can be reduced to “Depending on.”

　　3.The correct answer is A

　　The error in this sentence occurs at (A), where there is an improper idiom. The phrase “in addition to” is needed in place of “also.”

　　4.The correct answer is D

　　The error in this sentence occurs at (D), where there is an inappropriate verb form. The verb phrase “to have used” is needed to clearly express what Galileo was the first person to do.
