First version
Second version 
In this assignment, I’ve tried to explain each word using Ai.
For contraction, I changed the size of each letter and even overlap them to make the sense of the crowd.
For expansion, I changed the orientation to make us feel dizzy.
For sever, I used slide.
For unity, I just repeated it again and again.
For effervescent, I tried to make them look happy.
” stagnant” is one I was confused about, hope I can find a better way to illustrate it in the future.
