The humanoid league of robocup was introduced in 2002.
which of the following choices best defines the underlined verb? (was)
a. auxiliary
b. linking
c. action
d. collective

I think its B: Linking.

Explanation:

"was" is linking both films that were introduced in 2002.

the answer is both an appeal to ethos and logos (if that's what your question options were)

- "is not only a luminous passive watcher in the night sky, but it is a powerful force.

it does symbolizes love,   lust   and dreaming and is seen as a power symbolic force that determines and affects human behaviors and reactions.

in the context of the question it does remain you that he events are only taking place at night and the reader of the passage of time."
