The sentence requires a verb form that correctly completes a passive voice construction. The subject "The cake" is receiving the action, not performing it. We need a form of "to be" followed by the past participle of "make".
Correct Option: A) was made
The sentence requires a verb form that correctly conveys an ongoing action in the passive voice. We need to determine which option fits this grammatical structure.
Correct Option: A) is being built
The sentence requires a verb form that correctly conveys the action of sending the letter. The presence of "yesterday" indicates a past action. We need to determine if the subject "The letter" is performing the action (active voice) or receiving the action (passive voice).
Correct Option: B) was sent
This question tests the understanding of verb tenses, specifically how to use the past perfect tense to describe an action that happened before another action in the past.
Correct Option: B) had cleaned
To convert an interrogative sentence from active to passive voice, we need to identify the tense, the subject, the verb, and the object. The passive voice generally follows the structure: Object + helping verb (to be) + past participle of main verb + by + Subject. For interrogative sentences, the helping verb often comes first.
Correct Option: A) Is ice cream liked by you?
This option correctly transforms the active interrogative sentence in the simple present tense into its passive interrogative form. It uses the correct helping verb "Is" for the singular object "ice cream" and the past participle "liked".
The question asks to identify the voice of the given sentence: "By whom was this mess created?" We need to analyze the structure of the sentence, particularly the subject-verb relationship, to determine if it is active or passive.
Therefore, the sentence is in the passive voice.
Correct Option: B) Passive
