Question 11: Mark the letter A, B, C or D to indicate the underlined part that needs correction in each of the following questions. Question 28. Many different kinds of food are sold today have artificial flavoring added to them.

Knowledge of relative clauses

*Based on the sentence structure, we see that B is wrong. Notice that the sentence has two verbs, “are” and “have” at the same time, which are divided according to the tense of the sentence, so the first verb needs to be conjugated according to the reduced form of the relative clause. The verb “add” behind is a third verb in the sentence, but it has been reduced according to the relative clause to Vp2 form in the passive sense.

*Because the verb “sell” has a passive meaning here, as a rule, we omit the relative pronoun, omit “tobe” and keep the verb in the form “Vp2”.

Many foods that are sold today have artificial flavors added to them.

=> Answer B (are sold -> sold/ which (that) are sold)
