5. How does the researchers' experiment with Reddit contribute to the central idea of the text? Answer it as brief and simple as possible. Thank a lot.

B. It shows how the actions of people on social media can sway the actions of

other users.

Explanation:

The research conducted on Reddit, a news site shows that people's actions on social media can easily affect the way others react to such posts. A computer program was built by these researchers which randomly upvoted some posts, downvoted some, and left others that way.

It was noted that posts with higher upvotes had a higher chance of receiving more upvotes compared to those that recorded more downvotes. Posts with more downvotes had scores, 5% lower than the programs that were not even voted by the program.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
