Final answer:

Step-by-step explanation:
The level of blood alcohol concentration (BAC) at which measurable behavioral effects begin can vary depending on various factors such as age, sex, and overall health. However, alcohol intoxication typically begins after consuming two or more alcoholic drinks.
The legal limit for alcohol intoxication is a BAC of 0.08%. At this level, a person may experience impaired motor control, decision-making, coordination, blurred vision, and judgment interference. Higher BAC levels can lead to more severe effects such as sedation, coma, and even death.
It's important to note that individual tolerance and response to alcohol can vary, so the effects of alcohol differ widely between people.
