Problem: A Vestal's dress represented her status outside the usual categories that defined Roman women, with elements of both virgin bride and daughter, and Roman matron and wife. Unlike male priests, Vestals were freed of the traditional obligations of marrying and producing children, and were required to take a vow of chastity that was strictly enforced: a Vestal polluted by the loss of her chastity while in office was buried alive. Thus the exceptional honor accorded a Vestal was religious rather than personal or social; her privileges required her to be fully devoted to the performance of her duties, which were considered essential to the security of Rome.
What was the honor granted a Vestal ?
The answer is the following: religious

Problem: Swaziland's currency is pegged to the South African Rand, subsuming Swaziland's monetary policy to South Africa. Customs duties from the Southern African Customs Union, which may equal as much as 70% of government revenue this year, and worker remittances from South Africa substantially supplement domestically earned income. Swaziland is not poor enough to merit an IMF program; however, the country is struggling to reduce the size of the civil service and control costs at public enterprises. The government is trying to improve the atmosphere for foreign direct investment.
What currency is Swaziland bound to?
The answer is the following: South African Rand

Problem: Navigation is based on a variety of senses. Many birds have been shown to use a sun compass. Using the sun for direction involves the need for making compensation based on the time. Navigation has also been shown to be based on a combination of other abilities including the ability to detect magnetic fields (magnetoception), use visual landmarks as well as olfactory cues.
What is navigation based on?
The answer is the following: a variety of senses

Problem: Some birds, especially corvids and parrots, are among the most intelligent animals; several bird species make and use tools, and many social species pass on knowledge across generations, which is considered a form of culture. Many species annually migrate great distances. Birds are social, communicating with visual signals, calls, and bird songs, and participating in such social behaviours as cooperative breeding and hunting, flocking, and mobbing of predators. The vast majority of bird species are socially monogamous, usually for one breeding season at a time, sometimes for years, but rarely for life. Other species have polygynous ("many females") or, rarely, polyandrous ("many males") breeding systems. Birds produce offspring by laying eggs which are fertilized through sexual reproduction. They are usually laid in a nest and incubated by the parents. Most birds have an extended period of parental care after hatching. Some birds, such as hens, lay eggs even when not fertilized, though unfertilized eggs do not produce offspring.
Where are eggs usually laid?
The answer is the following:
nest
