Final answer:
Beer, wine, and vodka contain ethanol, with vodka having the highest concentration due to distillation. Beer and wine are fermented and have other components in addition to ethanol, while orange juice naturally contains no ethanol.
Step-by-step explanation:
The beverages that contain pure alcohol, which is ethyl alcohol or ethanol, include beer, wine, and vodka. However, not all of these beverages contain pure alcohol in the sense that they consist only of alcohol and water. Beer and wine are fermented drinks which contain ethanol, but they also have other components such as water, sugars, acids, and others. Vodka, on the other hand, is a distilled spirit, which means that it has a higher concentration of ethanol. Vodka is typically 40.0% ethanol by volume, especially if it is labeled as "80 proof." This indicates that it has a significant proportion of ethanol, but it is still diluted with water. Orange juice does not contain ethanol unless it has undergone fermentation to become an alcoholic beverage like wine.
Beer and wine have been part of human consumption since before the Middle Ages, and their ethanol content is a result of the natural fermentation of sugars found in grains (for beer) and grapes (for wine). The process of distillation did not become widespread until the 15th century, which led to the creation of higher-proof spirits such as vodka. Orange juice naturally contains no ethanol and thus does not include any type of alcohol unless altered to do so.
