Honey tastes sweet. (passive)

The correct answer is: Sweet is the taste of honey.

Explanation:

In this example, the active sentence is missing a transitive verb, which is necessary to make a proper passive form of the sentence. Therefore, we should use an intransitive verb to change a sentence into the passive voice and keep the correct structure of the passive voice.

Active form: Honey tastes sweet.

Passive form: Sweet is the taste of honey.
