. Which reasoning fallacies are present in the following statements (post hoc, ergo propter hoc or fallacy of composition)? a. The economy was expanding during all of the years that I was a student, but as soon as I graduated, the economy contracted.

Experimental research in small cities suggests that mandating work for welfare recipients increases their income. Therefore, we should mandate work requirements for all welfare recipients. c. You know that the computer lab at school gets very crowded at about 3:00 p.m. To avoid the crowds, you start going to the computer lab one hour earlier every day. However many students make the same decision, and now the computer lab becomes very crowded at 2:00 p.m. d. It always rains about an hour after you finish washing your car.

Post hoc, ergo propter hoc : Under this fallacy one event is said to be the cause of a later event simply because it occurred earlier.
Fallacy of composition: Under this fallacy it is assumed that what is true for one member of a certain group, will be true for all members of the group.
On the basis of the above definitions, the following are classified:

b) Fallacy of composition; just because mandating workforce increased some of the members income does not mean it'll be efficient for everyone in the group.
c) Post hoc, ergo propter hoc
d) Post hoc, ergo propter hoc
