Jawaban:

1. Is the homework done by your little sister at night?

2. Where is a horror film watched by Billy every Sunday night?

Penjelasan:

1. In the original sentence, the focus is on the subject "your little sister" performing the action "doing her homework." In the passive transformation, the subject becomes "the homework" and the verb changes to the passive form "is done." The agent (your little sister) is omitted or can be included using the preposition "by."

2. In the original sentence, the focus is on the subject "Billy" performing the action "watching a horror film." In the passive transformation, the subject becomes "a horror film" and the verb changes to the passive form "is watched." The agent (Billy) is omitted or can be included using the preposition "by."

In passive voice constructions, the subject of the sentence receives the action instead of performing the action. The passive voice is often used when the focus is on the object or when the doer of the action is unknown or less important.
