I pretty sure you it’s the third one c.
[C], a keyboard. A keyboard can pretty much do any basic tasks that a mouse can do, given that you know the short cuts.
For example,
CTRL + Esc to open the start menu, then use the arrow keys to navigate, and return key to select.
Windows Key + R to run a program, often in the form of an executable.
And obvious much, much more.
Hmm..This is a tough answer it all depends on how the students use their cell phones and if they can handle the privilege...And if they could "Sure why not" and you should monitor the students too
It looks like you've posted your question in wrong topic. Anyway I can help you. Performance steps for Guard Detainees and Completing a detainee are almost the same. If my memory serves me well, there are 6 performance steps. But the main rule is to be patient and ready for action. Always prepare your weapons to use, check if they are functional.
