Research has shown that playing video games is good for players' minds. video games improve players' thinking skills. a researcher from one study said, "it's difficult to find kids who earn poor grades but who do well in video games." video games challenge players to recognize patterns and think to survive in the game. players must use their brains to plan their next move to avoid losing the game. q: what logical fallacy is contained in the use of the statement made by the researcher in this paragraph? a) it is possible to tell if video game playing improves school grades. b) students who play computer games actually tend to perform poorly at school. c) students who play computer games only perform well when they are at school. d) it is not really possible to tell if video game playing improves school grades.

D) It is not really possible to tell if video game playing improves school grades.

Explanation:

In this example, a logical fallacy that is contained in the researcher's statement is the assumption that playing video games improves school grades. However, he provides no evidence that leads to us to accept this justification. He tells us that it is difficult to find kids who earn poor grades but do well in video games. However, one is not necessarily the cause of the other one. For example, it is possible that children who play video games are wealthier than those who do not. This might mean that they also benefit from tutors or from cultural experiences that allow them to get better grades in school.

yeah! it's really me with my homework, you should try it!

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.
