Example input: 	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.
Example output: 4
Example explanation: 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: WISDOM TEETH: IS IT WISE TO REMOVE THEM?\n\nCommon misunderstandings surround their name origin, removal reasons and pain sources\n\nWisdom teeth, also known as third molars, are the last teeth to grow in the back of\nthe mouth. Common misunderstandings surround their name origin, removal reasons and\npain sources, according to the Academy of General Dentistry, an organization of\ngeneral dentists dedicated to continuing education. \n\n"The name 'wisdom teeth' is age related - third molars don't erupt until teenage\nyears and beyond, when people theoretically are more wise to the world," says Trey\nPetty, DDS, FAGD, spokesperson for the Academy of General Dentistry.\n\nCommon reasons for wisdom teeth removal include impaction, pain and crowding of the\nother teeth, which are typical tooth growth characteristics.\n\n"If wisdom teeth are not visible, they are impacted or unable to erupt due to space\nand size limitations," says Dr. Petty. "Impacted teeth don't have enough room to grow,\nand will lay beneath the gums, which may or may not be a problem." \n\nPain and tooth crowding are also top wisdom teeth problems. "Adults have forgotten\nwhat normal pain from a growing tooth feels like," says Dr. Petty. Complications also\ncan arise when wisdom teeth partially erupt. The broken gum acts as a breeding ground\nfor bacteria and germs. \n\n"When wisdom teeth partially erupt, food gets caught in the gums and may cause an\ninfection, swelling, growth of a tumor or cyst and pain," says Dr. Petty. "If this\nhappens, consult a dentist before problems worsen and affect overall oral health."\n\n"If wisdom teeth have erupted, the key to preserving them is maintaining good oral\nhealth by brushing twice a day and going to see a dentist twice a year," says\nDr. Petty.
