Read the body paragraph from an essay on sound effects in film.Stretch a piece of waxed paper until it’s taut. Next, place it in front of the microphone. Then, pour uncooked rice onto the paper. This results in a sizzling sound that can be used for cooking on a hot stove or frying bacon.

The paragraph explains one specific way to make a sound effect: stretching waxed paper and pouring rice onto it creates a sizzling sound. “For example” introduces this procedure as an example, so choice A fits best. “As a result,” “Therefore,” and “In conclusion” suggest a conclusion or consequence, which does not match the paragraph’s purpose.
