On the simple assessment, if the answer is long enough on multiple choice, it will hide the half of the answer unless students put their cursor on it. This is very difficult for questions that involve having things in the proper order because they have to memorize what the other answers are.
For example, my question was "What is the order of the Chain of Infection?"
A. Organism, Reservoir, Portal of Exit...
B. Transmission, Portal of Entry, Organism...
C. Susceptible Host, Reservoir, Transmission...
Each option was missing half of the list, making it difficult to remember the order of the other options.
