Question

which sentence is in passive voice? the prospect of potentially living in a foreign country one day excites me. i am excited by the prospect of living in a foreign country one day.

Explanation:

Passive voice structures use a form of "to be" + past participle, where the subject receives the action. The first sentence uses "am excited" (a form of "to be" + past participle of "excite"), with the subject "I" receiving the feeling of excitement. The second sentence is active, with "the prospect" as the doer of the action "excites".

Answer:

I am excited by the prospect of living in a foreign country one day.
