Answer:
D) Is an important
B) Celebrated to mark
C) Leads the youngsters
Step-by-step explanation:
In the given questions, you need to pay attention to the tenses, voice, subject-verb agreement, and articles.
The given text tells us about a festival that takes place regularly, probably every year. The tense we use when we talk about fixed habits and repeated actions is the present simple tense. We should keep this in mind in all of the questions.
The subject-verb agreement is one of the rules of English grammar. According to it, the subject and verb must agree in number. This is why, in the first question, we should choose option D. The Wangala and festival are both singular, which means that the verb (is) should be as well.
Another thing to keep in mind when solving the first question is the article. A noun must be preceded by an article, in this case, indefinite article an. This is why option A is incorrect.
In the second question, we need to pay attention to the voice. Here, the passive voice is used to talk about an event that takes place every year. Using the verb being would indicate that it takes place right now, which is why it should be omitted. The verb celebrated should be used with the infinitive (to mark), which makes option C incorrect.
