Question

complete the text with the best conjunctive adverb.
some wild animals are primarily monogamous. swans, for instance, form bonds that last many years and sometimes for life. _______, french angelfish live, hunt, and travel with their chosen mates and form bonds that often last their entire lives.
nevertheless on the contrary likewise

Explanation:

The first part of the text talks about swans being monogamous (forming long - lasting bonds). The second part about French angelfish also shows them being monogamous (living, hunting, traveling with mates and forming long - lasting bonds). "Likewise" is used to show a similar situation. "Nevertheless" is for contrast in spite of something, and "On the contrary" is for a direct opposite, which don't fit here.

Answer:

Likewise
