Question 12: Mark the letter A, B, C, or D on your answer sheet to indicate the undelined part that needs correction in each of the following questions: An important factor should be considered is Mr. Lopez’s ability to keep the new restaurant going for several months with limited revenue.

Since the main verb of the sentence is “is”, we must add the relative pronoun after the noun to be modified to form a complete relative clause that modifies the subject of the sentence: An important factor which/ that should be considered is,.. or reduce the relative clause to: An important factor to be considered is… So answer A. should be considered is wrong. Must be changed to which/ that should be considered or to be considered.

An important factor to be considered is Mrs. Lopez’s ability to maintain the restaurant for a few months with limited revenue.
