You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Q: The minimum age to purchase and consume varies, but the most common age is 18 years. However, in North America the age limits varies between 18 and 21 years of age. Throughout the United States the minimum legal age to purchase any alcoholic beverage from a shop, supermarket, liquor store, bar, club or any other licensed premises is 21 years of age. In Canada each province can decide which minimum age limit is to be set to buy or consume alcohol. Most provinces have a minimum age of 19 years, while Alberta, Manitoba and Quebec have set a minimum age of 18 years. In South America all countries have set a minimum purchase age of 18 years, except for Guyana where minors aged 16 or 17 may consume a glass of beer, wine or cider in a restaurant provided they buy a meal, and Paraguay the only country with a minimum legal purchase and drinking age of 20 years.

A: can you buy alcohol at the age of 18?

Q: New Zealand has permitted dual or multiple citizenship since the creation of New Zealand citizenship on 1 January 1949, although dual citizens who actively acquired or exercised their other citizenship could lose their New Zealand citizenship if their continued citizenship was judged ``not conducive to the public good''. The modern wording is similar; dual citizens may lose New Zealand citizenship by acting ``in a manner that is contrary to the interests of New Zealand''. A New Zealand citizen who holds another citizenship may renounce their New Zealand citizenship (see below), although this may not be registered if they reside in New Zealand or the country is at war.

A: can i have dual citizenship in new zealand?

Q: Federal law requires background checks for commercial gun sales, but an exemption exists for private-party sales whereby ``Any person may sell a firearm to an unlicensed resident of the State where he resides as long as he does not know or have reasonable cause to believe the person is prohibited from receiving or possessing firearms under Federal law.'' Under federal law, private-party sellers are not required to perform background checks on buyers, record the sale, or ask for identification, whether at a gun show or other venue. This is in contrast to sales by gun stores and other Federal Firearms License (FFL) holders, who are required to perform background checks and record all sales on almost all buyers, regardless of whether the venue is their business location or a gun show. Some states have passed laws to require background checks for private sales with limited exceptions. Access to the National Instant Criminal Background Check System (NICS) is limited to FFL holders.

A:
is a background check required to buy a gun at a gun show?
