Answer :
Answer:
a) a mnemonic device
Explanation:
A mnemonic device is a learning technique that helps to encode information and to remember it.
Mnemonic device use retrieval cues, imagery, songs, rhyme, acronyms, sentences. All of these are used to help the original information to become associated with something more meaningful.
In this example, Tim needs to remember the spelling of "geography" so he learns a sentence that serves as an acronym (since the first letter of each word correspond with each letter of the word he needs to learn), so he's using a cue, in this case an acronym or sentence so he can associate the spelling (original information) with something more meaningful to him (the creative sentence of George)
Thus, the correct answer is a) a mnemonic device.
