In the context of remembering, a common technique to form a mnemonic is by:

a. adding extra details to the information that has to be remembered.
b. recording a speech in a tape recorder or a CD.
c. forming a word with the first letters of the information that has to be remembered.
d. paraphrasing the information that has to be remembered with related words.

c. forming a word with the first letters of the information that has to be remembered.
A mnemonic device associates a special word or very short statement with new and longer information. One of the most common mnemonic techniques is to form a word with the first letters of a list of items a person is trying to remember.
