direct object help

"A direct object is a noun or pronoun that receives the action of a transitive verb in an active sentence. It answers the questions what? or whom? about the transitive verb. Again, a simple direct object is only the noun or pronoun, whereas a complex direct object consists of that noun and pronoun and any modifiers that accompany it."

e.g.
Terry burnt the toast.
What did terry burn? - He burnt the toast.
Serena visited Kara.
Whom did Serena visit? - She visited Kara.

The direct object may also be compound.
eg.
Terry burnt the toast and the eggs.

What did Terry burn? - He burnt the toast and the eggs.


Therefore:

1. "Pasta"—yes (Is Pasta liked by you?)
2." seafood"--yes .
3. No (can’t be changed to passive voice)
4.”English”—yes (english is taught by me)
5. No
