Q. Although some ornithologists contend that the precursors of birds are/were arboreal creatures that glide from tree to tree, others believe that they were runners whose front limbs evolved into wings.

This is a SC question from Kaplan.

Although the solution suggests that usage of "were" is correct as the event is in past.
But, I feel that "are" should be used. Because , if the assumption is true then it would continue to hold its validity.
Can anyone please correct me if I am wrong.

Hi hareeshd,

IMO usage of WERE is correct.

precursors - arboreal creatures that came before birds. If those arboreal creatures are NOT ALIVE (as they are the PAST and present is BIRDS), then we must reference to them as PAST i.e. use WERE.

Quote:

contend - it is in present form. which means that the assumption is still valid.
believe - this also expresses the same idea.

you might think usage of GLIDE is incorrect. but that is also correct as there are too many creatures that are arboreal and are still around
