Answer: II and III
Both rhymes and acronyms are good memory tricks that can help you expand your vocabulary.
Rhymes consist of pairing up words that have similar sounds (such as pear-bear or picky-tricky). You can also expand on the rhyme by making verses and relating them to the meaning of the words.
Acronyms, on the other hand, are abbreviations that are formed by using the initial components of a phrase. Usually it is only the first letter that is chosen. Many government agencies and international organizations (such as those of the United Nations) use acronyms.
