Problem: The maximum distance at which a gun or missile can engage an aircraft is an important figure. However, many different definitions are used but unless the same definition is used, performance of different guns or missiles cannot be compared. For AA guns only the ascending part of the trajectory can be usefully used. One term is 'ceiling', maximum ceiling being the height a projectile would reach if fired vertically, not practically useful in itself as few AA guns are able to fire vertically, and maximum fuse duration may be too short, but potentially useful as a standard to compare different weapons.
Few AA guns are able to fire which way?
The answer is the following: vertically

Problem: Other animals, such as rabbits and rodents, practise coprophagia behaviours - eating specialised faeces in order to re-digest food, especially in the case of roughage. Capybara, rabbits, hamsters and other related species do not have a complex digestive system as do, for example, ruminants. Instead they extract more nutrition from grass by giving their food a second pass through the gut. Soft faecal pellets of partially digested food are excreted and generally consumed immediately. They also produce normal droppings, which are not eaten.
What is the practive of coprophagia behaviours?
The answer is the following: eating specialised faeces in order to re-digest food

Problem: Beyonce has been described as a having a wide-ranging sex appeal, with music journalist Toure writing that since the release of Dangerously in Love, she has "become a crossover sex symbol". Offstage Beyonce says that while she likes to dress sexily, her onstage dress "is absolutely for the stage." Due to her curves and the term's catchiness, in the 2000s, the media often used the term "Bootylicious" (a portmanteau of the words booty and delicious) to describe Beyonce, the term popularized by Destiny's Child's single of the same name. In 2006, it was added to the Oxford English Dictionary.
Which word spawned from a term used to describe Beyonce in 2006?
The answer is the following: Bootylicious

Problem: Favoring relatives (nepotism) or personal friends (cronyism) of an official is a form of illegitimate private gain. This may be combined with bribery, for example demanding that a business should employ a relative of an official controlling regulations affecting the business. The most extreme example is when the entire state is inherited, as in North Korea or Syria. A lesser form might be in the Southern United States with Good ol' boys, where women and minorities are excluded. A milder form of cronyism is an "old boy network", in which appointees to official positions are selected only from a closed and exclusive social network such as the alumni of particular universities instead of appointing the most competent candidate.
What is it called when friends are favored over other people?
The answer is the following:
cronyism
