This is not really a test. This is a wake up exercise to remind students to pay attention to the instructions before starting work, If they follow the instructions, written in the imperative voice, they do not have to do anything but sit quietly and try not to laugh at their classmates sweating over the odd questions.
The teacher will be able to tell within 2 minutes which students followed the instructions and which ones didn't.
It is a fun exercise to remind the students about alwasy paying attention to instructions. And we all know this is something they never do!
