Analytical reasoning sample questions

Seven Roman noblemen — Antonius, Brutus, Cassius, Decimus, Octavius, Servilius, and Vipsanius — have to decide whether they support or oppose the rule of dictator Julius Caesar. Those who support Caesar call themselves Patriots; those who oppose Caesar call themselves Liberators. Each of the seven noblemen aligns himself with one of the two groups according to the following principles:

Octavius and Cassius do not join the same group.

Antonius and Decimus do not join the same group.

If Decimus decides to be a Patriot, so does Servilius.
