You have the following code:

event2 += new PointerEventHandler(Target_PointerWheelChange);
event3 += new PointerEventHandler(Target_PointerReleased);
For each of the following statements, select Yes if the statement is true. Otherwise, select No.

Answer: 
Explanation:
*PointerPressed occurs when a single finger touches the screen.
*PointerWheelChanged occurs when the delta value of a mouse wheel changes.
*PointerReleased occurs when that same touch contact is lifted.
ThePointerReleased eventoccurs when the pointer device that previously initiated a Press action is released,
while within this element. Note that the end of a Press action is not guaranteed to fire a PointerReleased event;
other events may fire instead.
second box of answer might be wrong. I am not 100% sure(!)
PointerWheelChanged
Occurs when the mouse wheel is rotated.

I did a samll application due to test purposes.
I found that the event PointerWheelChanged was called using touchpad (two fingers gesture=> hold one, move second and it is scrolling in textbox)

to sum up: I would answer
1 – Yes
2 – Yes
3 – Yes
I think the correct answer is yes to all three:

Pointer events are raised by a variety of active input sources, including TOUCH, touchpad, pen, and mouse (they replace traditional mouse events.)
PointerPressed, PointerReleased and PointerWheelChanged are Pointer events.
