L is a decidable language because the Turing machine accepts it.
L is a recognizable language if TM M recognizes it.
<h3>How do you know if a language is decidable?</h3>
A language is said to be decidable only when there seems to exists a Turing machine that is said to accepts it,
Here, it tends to halts on all inputs, and then it answers "Yes" on words that is seen in the language and says "No" on words that are not found in the language. The same scenario applies to recognizable language.
So, L is a decidable language because the Turing machine accepts it.

Answers:(3) True
(4) Num Lock
Explanations:(3) To undo any task in most of the softwares including Blender, CTRL + Z is used. If you want to double check, go to preference -> Input -> Search for undo. You would see CTRL + Z shortcut there for one time undo (as shown in the picture 1 attached.) Hence (TRUE).

As you can see in the second image that the Top view is set to NumPad 7 (likewise others set to other numbers). In order to use the those numpad numbers, you must turn on the NumLock! Hence NumLock is the answer.
