Last year's Question of the day (04-Jul-12)

Answer the question based on the passage given below.

In addition, it is thought that the presence of other alcohols (fusel oils) and other by-products of alcoholic fermentation (also called congeners), exaggerate many of the symptoms; this probably accounts for the mitigation of the effects when distilled alcohol, particularly vodka, is consumed instead. A 2009 study provided evidence that darker-coloured liquors, such as bourbon, cause worse hangovers than lighter-coloured liquors, such as vodka. The higher amount of congeners found in darker liquors compared to lighter ones was indicated as the cause. Studies that attempt to compare hangover producing potential and hangover severity of different alcoholic drinks suggest the following ordering (starting with the least hangover-inducing): distilled ethanol diluted in fruit juice; beer; vodka; gin; white wine; whisky; rum; red wine; brandy.

Which of the following can be concluded from the passage?

OPTIONS

	1)	Whisky will give you a worse hangover than red wine, but it will be better than vodka.
	2)	White wine will give you more of a hangover than red wine but beer will give you less.
	3)	Congeners are contributing factors to hangovers, and the more you drink, the less of a chance you have of consuming them.
	4)	Beer is the least likely to give you a hangover and brandy is the most likely to give you one.
	5)	Rum will give you more of a hangover than white wine, but less than red wine.
