Q: 	Optical mice use an LED and a camera to rapidly
capture images of the surface beneath the mouse.
The infomation from the camera is analyzed by a
DSP (Digital Signal Processor) and used to detect
imperfections in the underlying surface and
determine motion. Some materials, such as glass,
mirrors or other very shiny, uniform surfaces
interfere with the ability of the DSP to
accurately analyze the surface beneath the mouse.
\nSince glass is transparent and very uniform, the
mouse is unable to pick up enough imperfections in
the underlying surface to determine motion.
Mirrored surfaces are also a problem, since they
constantly reflect back the same image, causing
the DSP not to recognize motion properly. When the
system is unable to see surface changes associated
with movement, the mouse will not work properly.
A: 4
Rationale: The passage talks about optical mice or mouse throughout which is a part of computer system. Thus, it is correctly classified to "Computers & Internet" 
Q: i found myself picking up snowboarding faster than skiing. by picking up, i mean i felt ready to take on the more intermmediate/advanced runs after a day or two of the bunny slopes. one board and 2 turns (backside and frontside) was a lot less to deal with than 2 poles and 2 skis and limbs flailing around in different directions. moguls are harder on a snowboard and more fun on skis. flatter runs are more frustrating on a snowboard. getting off the ski lift seems easier on skis
