Start by introducing the idea, as if this person is somebody who doesn’t know much about it. Then give three examples each on how it’s been both positive and negative, then add a transitioning sentence to be able to start your next paragraph.
Answer:
Linking verb.
Explanation:
It's not action because an action verb would be in the present tense.
And it's not a helping verb because it just isn't.
There are 27 helping verbs; Am, is, are, was and were, being, been, and be, Have, has, had, do, does, did, will, would, shall, should, may, might, must, can, could.
None of these are went, thus proving that it isn't a helping verb.
