Problem: The Sun (United Kingdom):

Television personality Piers Morgan, a former editor of the Daily Mirror and of The Sun's Bizarre pop column, has said that during the late 1980s, at Kelvin MacKenzie's behest, he was ordered to speculate on the sexuality of male pop stars for a feature headlined "The Poofs of Pop". He also recalls MacKenzie headlining a January 1989 story about the first same-sex kiss on the BBC television soap opera EastEnders "EastBenders", describing the kiss between Colin Russell and Guido Smith as "a homosexual love scene between yuppie poofs ... when millions of children were watching".

What did Piers Morgan offer opinions about in a late 1980s column?

A: the sexuality of male pop stars

Problem: After fans noticed Mercury's increasingly gaunt appearance in 1988, rumours began to spread that Mercury was suffering from AIDS. Mercury flatly denied this, insisting he was merely "exhausted" and too busy to provide interviews. The band decided to continue making albums, starting with The Miracle in 1989 and continuing with Innuendo in 1991. Despite his deteriorating health, the lead singer continued to contribute. For the last two albums made while Mercury was still alive, the band credited all songs to Queen, rather than specific members of the group, freeing them of internal conflict and differences. In 1990, Queen ended their contract with Capitol and signed with Disney's Hollywood Records, which has since remained the group's music catalogue owner in the United States and Canada. That same year, Mercury made his final public appearance when he joined the rest of Queen to collect the Brit Award for Outstanding Contribution to British Music.
After leaving Capitol, who did Queen sign with?
---
Answer: Disney's Hollywood Records

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Commercial solar water heaters began appearing in the United States in the 1890s. These systems saw increasing use until the 1920s but were gradually replaced by cheaper and more reliable heating fuels. As with photovoltaics, solar water heating attracted renewed attention as a result of the oil crises in the 1970s but interest subsided in the 1980s due to falling petroleum prices. Development in the solar water heating sector progressed steadily throughout the 1990s and growth rates have averaged 20% per year since 1999. Although generally underestimated, solar water heating and cooling is by far the most widely deployed solar technology with an estimated capacity of 154 GW as of 2007.
The solar water heaters introduced in the US in the 1890s saw growth until what time period?
A: the 1920s

Context and question: The photoelectric effect is the emission of electrons (called "photoelectrons") from a surface when light is shone on it. It was first observed by Alexandre Edmond Becquerel in 1839, although credit is usually reserved for Heinrich Hertz, who published the first thorough investigation in 1887. Another particularly thorough investigation was published by Philipp Lenard in 1902. Einstein's 1905 paper discussing the effect in terms of light quanta would earn him the Nobel Prize in 1921, when his predictions had been confirmed by the experimental work of Robert Andrews Millikan. The Nobel committee awarded the prize for his work on the photo-electric effect, rather than relativity, both because of a bias against purely theoretical physics not grounded in discovery or experiment, and dissent amongst its members as to the actual proof that relativity was real.
What did Einstein with the 1921 Nobel Prize for?
Answer: his work on the photo-electric effect

Question: After the end of the late Middle Ages period, the Renaissance would spread unevenly over continental Europe from the southern European region. The intellectual transformation of the Renaissance is viewed as a bridge between the Middle Ages and the Modern era. Europeans would later begin an era of world discovery. Combined with the influx of classical ideas was the invention of printing which facilitated dissemination of the printed word and democratized learning. These two things would lead to the Protestant Reformation. Europeans also discovered new trading routes, as was the case with Columbus's travel to the Americas in 1492, and Vasco da Gama's circumnavigation of Africa and India in 1498. Their discoveries strengthened the economy and power of European nations.
Is there an answer to this question: What effect did the discoveries of Columbus and da Gama have on European nations?

Answer: strengthened the economy and power

Question: The outbreak of World War I in 1914 was precipitated by the rise of nationalism in Southeastern Europe as the Great Powers took up sides. The Allies defeated the Central Powers in 1918. During the Paris Peace Conference the Big Four imposed their terms in a series of treaties, especially the Treaty of Versailles.
Is there an answer to this question: When did a stalemate occur in World War I?

Answer:
unanswerable
