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).
(4) As in blender, during the scene creation, the designers usually use top, left, right or bottom view. Blender has the built-in keys set for those views.

Hence NumLock is the answer.

The rows correspond to the subject
The columns correspond to the object
What does each cell in the matrix contain? Answer: Each cell is the set of access rights for that subject to that object.
