If this is an FLVS course then you need to go back to the first lesson in the module and you will find a page full of words, You need to pick 5 words and right them down on a note pad or in a program on your computer. You need to write down the word and its definition. Then in this assessment you will write down the word and the definition.
Hope this helps! If it doesn't feel free to PM me and ask me to explain it more. :^)
