Answer 1

Here: https://stackoverflow.com/questions/826782/how-to-disable-text-selection-highlighting

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;

Disallow them from being able to answer when the window's onBlur event is fired. They can still use other devices, but they won't be able to cheat on the same computer.

Answer 2

Maybe using custom font and create spesific blank characters?
