# Answer 1
# Mnemonics are clever patterns or systems designed to help us remember things in an easy
# and recognisable way.
# Mnemonic variable names serve a similar purpose.
# They are clever variable names which make it apparent what the program/code aims to achieve.
# It is a good practice to use them as anyone can understand what each variable stores and 
# thereby what the program does.
# The same purpose can be achieved by comments, however mnemonic variable names are more 
# efficient.
