Your question is missing the options. I've found the complete question online. It is as follows:
On the day Janet was scheduled to give her speech, her class was relocated into an auditorium. Janet couldn't quite overcome the feeling of isolation she felt as she spoke to her twenty classmates in a room that could seat 500. Which of the following elements is most responsible for Janet's reaction?
A) Feedback
B) Context
C) Information source
D) Channel
Answer:
The best answer is letter B) Context
Explanation:
The context of a speech involves several aspects, such as the place and time, the purpose, the traits of the audience, how big the audience and the place are, what types of technology will be used etc. From what was explained in the question, Janet's speech had a sudden change in context that impacted Janet negatively. She was prepared to speak to 20 people, quite an "intimate" audience. She probably rehearsed her speech having in mind a smaller room, maybe not even considering the use of a microphone. When she was asked to speak at a room that could seat 500, the whole context change. She felt isolated, surrounded by emptiness instead of the warmth of 20 people in a smaller room. She probably had to speak louder or use a microphone. The change in context was so big that it interfered with Janet's previous preparation and caused her to react negatively.
Read the passage from Sugar Changed the World.
In the 1400s, Spain and Portugal were competing to explore down the coast of Africa and find a sea route to Asia. That way, they could have the prized Asian spices they wanted without having to pay high prices to Venetian and Muslim middlemen. Spanish and Portuguese sailors searching for that sea route conquered the Canary Islands and the Azores. Soon they began building Muslim-style sugar plantations on the islands, some of them staffed by slaves purchased from nearby Africa. One sailor came to know these islands particularly well because he traded in "white gold"—sugar. And then, as he set off on his second voyage across the sea to what he thought was Asia, he carried sugar cane plants from Gomera, one of the Canary Islands, with him on his ship. His name was Christopher Columbus.
