Which of the following was germany permitted to keep under the terms of the treaty of versailles?

military equipment
financial aid for cities
a standing army
rights to all territories

Germany was permitted to keep a standing army.

Germany was demilitarized to prevent them from assuming power again, so they weren't permitted to keep much of their military equipment.

Germany couldn't keep financial aid for cities; it was forced to pay war reparations which practically crippled it economically.

The territories that Germany won during the war was confiscated.

A standing army (really its not exactly an army, because it was more of a security-defensive group of men, for most of their weaponary and technology associating with military were confiscated) 

hope this helps

Democracy and darwinism would be my answer.
