Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions

If we believe that clothing has to do with covering the body, and costumes with the choice of a particular form of garment for a particular use, then we can say that clothing depends primarily on such physical conditions as climate, health, and textile manufacture, whereas costumes reflect social factors such as religious beliefs, aesthetics, personal status, and the wish to be distinguished from or to emulate our fellows. The ancient Greeks and the Chinese believed that we first covered our bodies for some physical reason such as protecting ourselves from the weather elements.
