What type of alcohol do people consume?

Which beverage contains the most ethyl alcohol?
Champagne usually contains 12 percent ethyl alcohol, while beer has 4.5 percent and wine has 11 percent.
At what blood alcohol concentration level (BAC) can a person fall into a coma?
At 0.35 to 0.5 percent BAC, a person may become unconscious and their heart rate could slow, possibly leading to coma or even death.
Which part of the brain does alcohol affect first?
Alcohol affects various portions of the brain, beginning with the cerebral cortex. The cerebral cortex manages perception, judgment and speech. As the BAC increases, more areas of the brain are affected.
When affected by alcohol, which area of the brain causes fuzzy memories and exaggerated emotions?
The brain's limbic system, which controls emotions and memory, consists of structures like the hippocampus and septal area. As alcohol affects this system, the drinker is subject to exaggerated states of emotion, like anger, aggressiveness, withdrawal and memory loss.

During a performance test, you are asked to bring your finger to your nose with your eyes closed. If you are unable to perform this action, what part of the brain is affected?
The cerebellum controls fine movements, so if it's not functioning properly, the smooth motion of bringing your finger to your nose would be shaky or jerky.
What three variables affect the absorption rate of alcohol?
Alcohol absorption depends upon the following things: concentration of alcohol in the beverage, the level of carbonation in the beverage and the amount of food in your stomach.
At what blood alcohol concentration level (BAC) can a person die?
A person can die with a BAC over .50 percent.
Alcohol can be made by three methods. Which of the following is NOT one of them?
The chemical combination of oxygen and carbon monoxide produces carbon dioxide, not alcohol. Alcohol can be made by fermentation, fossil fuels and the combination of hydrogen and carbon monoxide.
