WRONG:

COMPRISED OF

RIGHT:

COMPOSED OF

Although “comprise” is used primarily to mean “to include,” it is also often stretched to mean “is made up of”—a meaning that some critics object to. The most cautious route is to avoid using “of” after any form of “comprise” and substitute “is composed of” in sentences like this: “Jimmy’s paper on Marxism was composed entirely of sentences copied off the Marx Brothers Home Page.”
