The best way to make sure that a collaborative discussion stays on track and everyone is listening to each other is to:
A. discuss only topics on which everyone agrees.
B. insist that your ideas are correct.
C. summarize points of agreement and disagreement.
D. repeat an opinion until everyone agrees.

c

Explanation:

you want to keep everyone on track, so you can all talk about your agreements and disagreements, so everyone feels ‘included’ in the conversation. I mean I guess a would be correct, but that is not the right way to get an answer.

if you wanna put a, be my guest, but I believe it is c. sorry if this is wrong, just trying to help! :)

well since twins have about the same dna they dont have one think in common which is the figer print. nobodys fingerprint is the same. if your using twin you would most likely get around the same results for both of them because of the genetics.. i hope this
