The rules of this test are simple: it's your job to determine whether an argument
is *valid* or not.

All the arguments are syllogisms. Here is a standard example:

All humans are mortal

All Greeks are humans

Therefore, all Greeks are mortal

An argument is valid if and only if the conclusion *necessarily follows from the premises*.
Thus, the argument above is valid, because if all humans are mortal, and if all
Greeks are human, it follows as a matter of logical necessity that all Greeks are
mortal.

It is important to stress that this kind of logical entailment has nothing to do
with the truth of the premises or conclusion. It is only about working out whether
the conclusion necessarily *follows* from the premises.

This is really all the information you need to take the test. You will be asked to assess the validity of 15 syllogisms, and this is just a matter of saying whether the conclusion is entailed by the premises. You can do that, surely?

Oh, one final thing. You'll be timed. The clock starts when you hit the button below.

Really Deep Thought

Religion is the only means of introducing some notion of the high significance of life into the uncultivated heads of the masses, deep sunk as they are in mean pursuits and uncultivated drudgery.--
