3. How do logical fallacies weaken a writer's argument? They represent the writer's opinion rather than details that readers will recognize as facts.
They attempt to manipulate a reader's emotions rather than presenting evidence.
They make the writer's argument seem biased toward a particular point of view.
They provide false reasons in support of a claim, making the writer seem less credible.

They provide false reasons in support of a claim, making the writer seem less credible.

Explanation:

The use of fallacy is using faulty arguments to support the opinion. At the first glance, the fallacious opinion can seem better than it is, but it is not supported by facts, and the reader can have the feeling the writer is dishonest.

By using fallacies, the writer is discrediting his work and words.

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.

the anwser is went creeping down the river again, across the wide lonely marshes to the sea.

i longed to go with them out into the world to seek my fortune in foreign lands—africa, india, china and peru!

and, dreaming of the lands i had never seen, i'd sit on there, watching till they were out of sight.
