Select all that apply. a participle may be used as a(n): linking verb object of a preposition predicate nominative appositive adjective complement subject indirect object

Participles can be classified in past and present; for example:  

With regular verbs such as help:

Present Participle: Helping

Past Participle: Helped

With irregular verbs such as bring:

Present participle: Bringing

Past participle: Brought  

Then, option 5 (Adjective complement) is not correct because participles can be used as adjectives for example in this sentence:

The walking men  

But the function of the participle walking would be pre-modifier of the noun men, not adjective complement.  

The correct options are object of a preposition (2), subject (6) and indirect object (7) and the participles in these cases are used as noun. Whenever a present participle is functioning as a noun, it is called gerund.  For example:

Marcus decided to shut up instead of criticizing his friend. (Object of a preposition)

Running exhausts John (Subject)

We gave bungee jumping a chance (Indirect object)

the word that best matches the meaning of the expression "went to the big ocean" is died.

the goldfish died, which is why the father looks at the children mournfully. the "big ocean" is the father's way of saying fish heaven. he could have just said that the goldfish died, but this way, the children imagine the fish in a bigger, better place instead of just picturing a dead fish.
