Problem: Arsenal F.C.:

Unveiled in 1888, Royal Arsenal's first crest featured three cannon viewed from above, pointing northwards, similar to the coat of arms of the Metropolitan Borough of Woolwich (nowadays transferred to the coat of arms of the Royal Borough of Greenwich). These can sometimes be mistaken for chimneys, but the presence of a carved lion's head and a cascabel on each are clear indicators that they are cannon. This was dropped after the move to Highbury in 1913, only to be reinstated in 1922, when the club adopted a crest featuring a single cannon, pointing eastwards, with the club's nickname, The Gunners, inscribed alongside it; this crest only lasted until 1925, when the cannon was reversed to point westward and its barrel slimmed down.

Where did Arsenal play prior to 1913?

A: unanswerable


Problem: Uranium was also used in photographic chemicals (especially uranium nitrate as a toner), in lamp filaments for stage lighting bulbs, to improve the appearance of dentures, and in the leather and wood industries for stains and dyes. Uranium salts are mordants of silk or wool. Uranyl acetate and uranyl formate are used as electron-dense "stains" in transmission electron microscopy, to increase the contrast of biological specimens in ultrathin sections and in negative staining of viruses, isolated cell organelles and macromolecules.
In addition to wool, what is uranium salt a mordant of?

Context and question: Upon its founding in 1949, West Germany had eleven states. These were reduced to nine in 1952 when three south-western states (South Baden, Württemberg-Hohenzollern, and Württemberg-Baden) merged to form Baden-Württemberg. From 1957, when the French-occupied Saar Protectorate was returned and formed into the Saarland, the Federal Republic consisted of ten states, which are referred to as the "Old States" today. West Berlin was under the sovereignty of the Western Allies and neither a Western German state nor part of one. However, it was in many ways de facto integrated with West Germany under a special status.
Which state was West Berlin apart of?
Answer: neither a Western German state nor part of one


Question: Many flags of the Islamic world are green, as the color is considered sacred in Islam (see below). The flag of Hamas, as well as the flag of Iran, is green, symbolizing their Islamist ideology. The 1977 flag of Libya consisted of a simple green field with no other characteristics. It was the only national flag in the world with just one color and no design, insignia, or other details. Some countries used green in their flags to represent their country's lush vegetation, as in the flag of Jamaica, and hope in the future, as in the flags of Portugal and Nigeria. The green cedar of Lebanon tree on the Flag of Lebanon officially represents steadiness and tolerance.
Is there an answer to this question: Iran is the only flag in the world with just what?

House minority leaders also hold joint news conferences and consult with their counterparts in the Senate—and with the president if their party controls the White House. The overall objectives are to develop a coordinated communications strategy, to share ideas and information, and to present a united front on issues. Minority leaders also make floor speeches and close debate on major issues before the House; they deliver addresses in diverse forums across the country; and they write books or articles that highlight minority party goals and achievements. They must also be prepared "to debate on the floor, ad lib, no notes, on a moment's notice," remarked Minority Leader Michel. In brief, minority leaders are key strategists in developing and promoting the party's agenda and in outlining ways to neutralize the opposition's arguments and proposals.
What is the overall party strategy for minority leader?
A:
develop a coordinated communications strategy, to share ideas and information, and to present a united front on issues
