Input: Article: Hops contain several characteristics that brewers desire in beer. Hops contribute a bitterness that balances the sweetness of the malt; the bitterness of beers is measured on the International Bitterness Units scale. Hops contribute floral, citrus, and herbal aromas and flavours to beer. Hops have an antibiotic effect that favours the activity of brewer's yeast over less desirable microorganisms and aids in "head retention", the length of time that a foamy head created by carbonation will last. The acidity of hops is a preservative.

Now answer this question: The acidity of what ingredient acts as a preservative in beer?

Output: hops


Article: The administration of London is formed of two tiers—a city-wide, strategic tier and a local tier. City-wide administration is coordinated by the Greater London Authority (GLA), while local administration is carried out by 33 smaller authorities. The GLA consists of two elected components; the Mayor of London, who has executive powers, and the London Assembly, which scrutinises the mayor's decisions and can accept or reject the mayor's budget proposals each year. The headquarters of the GLA is City Hall, Southwark; the mayor is Boris Johnson. The mayor's statutory planning strategy is published as the London Plan, which was most recently revised in 2011. The local authorities are the councils of the 32 London boroughs and the City of London Corporation. They are responsible for most local services, such as local planning, schools, social services, local roads and refuse collection. Certain functions, such as waste management, are provided through joint arrangements. In 2009–2010 the combined revenue expenditure by London councils and the GLA amounted to just over £22 billion (£14.7 billion for the boroughs and £7.4 billion for the GLA).

Question: How many boroughs does London consist of?
Ans: 32


Here is a question about this article: After working on various solo projects during 1988 (including Mercury's collaboration with Montserrat Caballé, Barcelona), the band released The Miracle in 1989. The album continued the direction of A Kind of Magic, using a pop-rock sound mixed with a few heavy numbers. It spawned the European hits "I Want It All", "Breakthru", "The Invisible Man", "Scandal", and "The Miracle". The Miracle also began a change in direction of Queen's songwriting philosophy. Since the band's beginning, nearly all songs had been written by and credited to a single member, with other members adding minimally. With The Miracle, the band's songwriting became more collaborative, and they vowed to credit the final product only to Queen as a group.
What is the answer to this question: Who did Freddie Mercury collaborate with in 1988?
****
So... Montserrat Caballé, Barcelona


The problem: Answer a question about this article:
The departures of Núñez and van Gaal were hardly noticed by the fans when compared to that of Luís Figo, then club vice-captain. Figo had become a cult hero, and was considered by Catalans to be one of their own. However, Barcelona fans were distraught by Figo's decision to join arch-rivals Real Madrid, and, during subsequent visits to the Camp Nou, Figo was given an extremely hostile reception. Upon his first return, a piglet's head and a full bottle of whiskey were thrown at him from the crowd. The next three years saw the club in decline, and managers came and went. van Gaal was replaced by Llorenç Serra Ferrer who, despite an extensive investment in players in the summer of 2000, presided over a mediocre league campaign and a humiliating first-round Champions League exit, and was eventually dismissed late in the season. Long-serving coach Carles Rexach was appointed as his replacement, initially on a temporary basis, and managed to at least steer the club to the last Champions League spot on the final day of the season. Despite better form in La Liga and a good run to the semi-finals of the Champions League, Rexach was never viewed as a long-term solution and that summer Louis van Gaal returned to the club for a second spell as manager. What followed, despite another decent Champions League performance, was one of the worst La Liga campaigns in the club's history, with the team as low as 15th in February 2003. This led to van Gaal's resignation and replacement for the rest of the campaign by Radomir Antić, though a sixth-place finish was the best that he could manage. At the end of the season, Antić's short-term contract was not renewed, and club president Joan Gaspart resigned, his position having been made completely untenable by such a disastrous season on top of the club's overall decline in fortunes since he became president three years prior.
After Barcelona's poor showing in the 2003 season , who resigned from the presidency?
****
The answer: Joan Gaspart


Problem: Please answer a question about the following article about FC Barcelona:
Prior to the 2011–2012 season, Barcelona had a long history of avoiding corporate sponsorship on the playing shirts. On 14 July 2006, the club announced a five-year agreement with UNICEF, which includes having the UNICEF logo on their shirts. The agreement had the club donate €1.5 million per year to UNICEF (0.7 percent of its ordinary income, equal to the UN International Aid Target, cf. ODA) via the FC Barcelona Foundation. The FC Barcelona Foundation is an entity set up in 1994 on the suggestion of then-chairman of the Economical-Statutory Committee, Jaime Gil-Aluja. The idea was to set up a foundation that could attract financial sponsorships to support a non-profit sport company. In 2004, a company could become one of 25 "Honorary members" by contributing between £40,000–60,000 (£54,800–82,300) per year. There are also 48 associate memberships available for an annual fee of £14,000 (£19,200) and an unlimited number of "patronages" for the cost of £4,000 per year (£5,500). It is unclear whether the honorary members have any formal say in club policy, but according to the author Anthony King, it is "unlikely that Honorary Membership would not involve at least some informal influence over the club".
How much does Barcelona donate to UNICEF per year?
A: €1.5 million


Question: Read this and answer the question

In 1977, the Supreme Court's Coker v. Georgia decision barred the death penalty for rape of an adult woman, and implied that the death penalty was inappropriate for any offense against another person other than murder. Prior to the decision, the death penalty for rape of an adult had been gradually phased out in the United States, and at the time of the decision, the State of Georgia and the U.S. Federal government were the only two jurisdictions to still retain the death penalty for that offense. However, three states maintained the death penalty for child rape, as the Coker decision only imposed a ban on executions for the rape of an adult woman. In 2008, the Kennedy v. Louisiana decision barred the death penalty for child rape. The result of these two decisions means that the death penalty in the United States is largely restricted to cases where the defendant took the life of another human being. The current federal kidnapping statute, however, may be exempt because the death penalty applies if the victim dies in the perpetrator's custody, not necessarily by his hand, thus stipulating a resulting death, which was the wording of the objection. In addition, the Federal government retains the death penalty for non-murder offenses that are considered crimes against the state, including treason, espionage, and crimes under military jurisdiction.

For what offense did Coker v. Georgia forbid the death penalty?
Answer:
rape of an adult woman
