Answer:
B."Those two claims don't add up, but maybe we can find another source that helps us sort them out."
Step-by-step explanation:
When a group discussion is organized it is necessary to remember that everyone has the right to state his or her statements in the same way that everyone has the right to disagree with the spoken statements as long as everyone maintains respect among the group colleagues.
When a student disagrees with an affirmation that has been made during a group discussion; the best way to resolve this contradiction is to remain calm and to look for new sources of research that confirm or contradict the spoken statement. That is, when two statements do not add up, it is best to find another source that will help the group solve them.
