Problem: Please answer a question about the following article about Adult contemporary music:
Another big impetus for the evolution of the AC radio format was the popularity of easy listening or "beautiful music" stations, stations with music specifically designed to be purely ambient. Whereas most easy listening music was instrumental, created by relatively unknown artists, and rarely purchased, AC was an attempt to create a similar "lite" format by choosing certain tracks (both hit singles and album cuts) of popular artists.
What type of format were adult contemporary and easy listening stations meant to share?
A: lite

In the Romantic era, the modern piano, with a more powerful, sustained tone and a wider range took over from the more delicate-sounding fortepiano. In the orchestra, the existing Classical instruments and sections were retained (string section, woodwinds, brass and percussion), but these sections were typically expanded to make a fuller, bigger sound. For example, while a Baroque orchestra may have had two double bass players, a Romantic orchestra could have as many as ten. "As music grew more expressive, the standard orchestral palette just wasn't rich enough for many Romantic composers." New woodwind instruments were added, such as the contrabassoon, bass clarinet and piccolo and new percussion instruments were added, including xylophones, drums, celestes (a bell-like keyboard instrument), large orchestral harps, bells, and triangles and even wind machines for sound effects.

What wasn't rich enough for many Romantic composers?
Answer: the standard orchestral palette

Problem: HIV/AIDS rate in Nigeria is much lower compared to the other African nations such as Kenya or South Africa whose prevalence (percentage) rates are in the double digits. As of 2012[update], the HIV prevalence rate among adults ages 1549 was just 3.1 percent. As of 2014[update], Life expectancy in Nigeria is 52.62 years on average according to CIA, and just over half the population have access to potable water and appropriate sanitation; As of 2010[update], the Infant mortality is 8.4 deaths per 1000 live births.
What is Nigeria's life expectancy?
The answer is the following: 52.62 years

The nervous system is large relative to the bird's size. The most developed part of the brain is the one that controls the flight-related functions, while the cerebellum coordinates movement and the cerebrum controls behaviour patterns, navigation, mating and nest building. Most birds have a poor sense of smell with notable exceptions including kiwis, New World vultures and tubenoses. The avian visual system is usually highly developed. Water birds have special flexible lenses, allowing accommodation for vision in air and water. Some species also have dual fovea. Birds are tetrachromatic, possessing ultraviolet (UV) sensitive cone cells in the eye as well as green, red and blue ones. This allows them to perceive ultraviolet light, which is involved in courtship. Birds have specialized light-sensing cells deep in their brains that respond to light without input from eyes or other sensory neurons. These photo-receptive cells in the hypothalamus are involved in detecting the longer days of spring, and thus regulate breeding activities.
Which bird system is large relative to a bird's size?
nervous system

Input: Hunting
While it is undisputed that early humans were hunters, the importance of this for the emergence of the Homo genus from the earlier Australopithecines, including the production of stone tools and eventually the control of fire, are emphasised in the hunting hypothesis and de-emphasised in scenarios that stress omnivory and social interaction, including mating behaviour, as essential in the emergence of human behavioural modernity. With the establishment of language, culture, and religion, hunting became a theme of stories and myths, as well as rituals such as dance and animal sacrifice.

What became a theme of stories and myths?
Output: hunting

Problem: Please answer a question about the following article about Prime minister:
From 1721 this was the Whig politician Robert Walpole, who held office for twenty-one years. Walpole chaired cabinet meetings, appointed all the other ministers, dispensed the royal patronage and packed the House of Commons with his supporters. Under Walpole, the doctrine of cabinet solidarity developed. Walpole required that no minister other than himself have private dealings with the king, and also that when the cabinet had agreed on a policy, all ministers must defend it in public, or resign. As a later prime minister, Lord Melbourne, said, "It matters not what we say, gentlemen, so long as we all say the same thing."
For how long did Robert Walpole serve as prime minister?
A:
twenty-one years
