Cora is giving a presentation on marble collecting and has brought her own marble collection to show to the audience. She is not sure, however, the best way to present the marbles to her audience so that everyone can see them. What should Cora do?
a. Cora should pass the marbles around as she delivers her speech.
b. Cora should have the audience stand up and gather around her as she delivers her speech.
c. Cora should ask for a volunteer to carry the marble jar around the room as she delivers her speech.
d. Cora should invite the audience to come up and see the marbles after her speech, as long as no other speakers are scheduled to follow her.

Option(d) is correct option

Explanation:

According to the question,Cora should give the complete speech first so that audience can listen to it and attain information about marbles.After she finishes the speech she can let audience come on stage to have a look on her marbles in coordinated manner if no other speaker has to give speech further.This will not create chaos among audience and disturbance will be eliminated.

Other options are incorrect because passing marbles among audience ,letting volunteers carry marble to audience and gathering audience to see her marbles in group during her speech will tamper her focus from speech and audience might lose interest from speech and notice marbles only.Thus, the correct option is option(d).
