Explanation:

your answer

Answer 2

Answer:

was

Explanation:

"Twenty-thousand Leagues Under the Sea" is a novel written by Jules Vern but since the verb following is "written" (a participle), I'm going to assume it was meant to be a past perfect tense. However, if there is a complementary between the verb to be and the participle, it could be "is". Another point is, if given any time period in the sentence, it will definitely be a past perfect.

Hope this helped.
