Detailed Instructions: You are given a passage. Using the information present in the passage, you need to classify it into one of the 10 topics: 0 - 'Society & Culture', 1 - 'Science & Mathematics', 2 - 'Health', 3 - 'Education & Reference', 4 - 'Computers & Internet', 5 - 'Sports', 6 - 'Business & Finance', 7 - 'Entertainment & Music', 8 - 'Family & Relationships', 9 - 'Politics & Government'.
See one example below:
Problem: 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.

Since 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.
Solution: 4
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"

Problem: This is to expand on another person's answer, which was correct but missing some important steps or explanation. This cure is a bonafide medical and scientific cure. The get rid of hiccups, you must deprive oxygen from the muscle that is causing hiccups. No oxygen to that muscle, it can't burn energy, no energy, no hiccups.

So what needs to be done is to simulate DROWNING. We must trick the body to think it is drowning. This will cause it to divert oxygen from unimportant parts of the body, like that muscle causing hiccups, to more important parts like the heart, the brain, the organs, etc.

So...take a glass of water, slowly exhale. Pinch your nose. Take about 5 or 6 sips of water (or more until you can't take it any longer) from the glass...making sure you are taking in WATER ONLY. Do NOT sip any air along with the water. Stop.

Hold your breath for a few seconds, and inhale slowly. The hiccups should disappear. If not repeat.

I have found this works 90% of the time. It only fails to work if there really is something stuck in your throat that really needs to be expelled by hiccups or coughing, or drinking lots of water.
