Problem: Capital punishment in the United States:

Pharmaceutical companies whose products are used in the three-drug cocktails for lethal injections are predominantly European, and they have strenuously objected to the use of their drugs for executions and taken steps to prevent their use. For example, Hospira, the sole American manufacturer of sodium thiopental, the critical anesthetic in the three-drug cocktail, announced in 2011 that it would no longer manufacture the drug for the American market, in part for ethical reasons and in part because its transfer of sodium thiopental manufacturing to Italy would subject it to the European Union's Torture Regulation, which forbids the use of any product manufactured within the Union for torture (as execution by lethal injection is considered by the Regulation). Since the drug manufacturers began taking these steps and the EU regulation ended the importation of drugs produced in Europe, the resulting shortage of execution drugs has led to or influenced decisions to impose moratoria in Arkansas, California, Kentucky, Louisiana, Mississippi, Montana, Nevada, North Carolina, and Tennessee.

When did Hospira cease to manufacture its lethal injection drug for the United States?

A: 2011

Problem: Though pesticide regulations differ from country to country, pesticides, and products on which they were used are traded across international borders. To deal with inconsistencies in regulations among countries, delegates to a conference of the United Nations Food and Agriculture Organization adopted an International Code of Conduct on the Distribution and Use of Pesticides in 1985 to create voluntary standards of pesticide regulation for different countries. The Code was updated in 1998 and 2002. The FAO claims that the code has raised awareness about pesticide hazards and decreased the number of countries without restrictions on pesticide use.
What commitee deals with differences in rules governing the use of pesticides among different countries?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The formation of the party was formally announced at Sydney Town Hall on 31 August 1945. It took the name "Liberal" in honour of the old Commonwealth Liberal Party. The new party was dominated by the remains of the old UAP; with few exceptions, the UAP party room became the Liberal party room. The Australian Women's National League, a powerful conservative women's organisation, also merged with the new party. A conservative youth group Menzies had set up, the Young Nationalists, was also merged into the new party. It became the nucleus of the Liberal Party's youth division, the Young Liberals. By September 1945 there were more than 90,000 members, many of whom had not previously been members of any political party.
Where was the formation of the UAP party officially announced?
A: unanswerable

Context and question: In 1853, Victoria gave birth to her eighth child, Leopold, with the aid of the new anaesthetic, chloroform. Victoria was so impressed by the relief it gave from the pain of childbirth that she used it again in 1857 at the birth of her ninth and final child, Beatrice, despite opposition from members of the clergy, who considered it against biblical teaching, and members of the medical profession, who thought it dangerous. Victoria may have suffered from post-natal depression after many of her pregnancies. Letters from Albert to Victoria intermittently complain of her loss of self-control. For example, about a month after Leopold's birth Albert complained in a letter to Victoria about her "continuance of hysterics" over a "miserable trifle".
Why did members of the clergy oppose the use of chloroform?
Answer: considered it against biblical teaching

Question: Between 1975 and 2009, Olympic Airways (known after 2003 as Olympic Airlines) was the country's state-owned flag carrier, but financial problems led to its privatization and relaunch as Olympic Air in 2009.

Is there an answer to this question: What year did Olympic Air lose an award as Top Domestic Airline?
