28. The sentence that contains a shift in tense is: "Once he had finished the book, he will write the report."

To identify a shift in tense, we need to look for a change in verb tense within the sentence. In this case, we have the past perfect tense "had finished" followed by the future tense "will write." The shift from past perfect to future tense indicates a change in time and therefore a shift in tense within the sentence.

29. The sentence with the passive voice verb is: "My skates are being repaired."
To identify the passive voice, we need to look for a verb that has a form of "be" followed by a past participle verb (e.g., repaired, done, written). In this case, the verb "are being repaired" is in the passive voice because it uses the form of "be" (are) followed by the past participle verb "repaired."

30. The sentence with the active voice verb is: "Our winner will be chosen by the artists themselves."
To identify the active voice, we need to look for a sentence where the subject performs the action of the verb. In this case, the subject "artists" performs the action of the verb "chosen" on the object "winner." This indicates that the sentence is in the active voice.
