The Aravalli Range and the lands to the east and southeast of the range are generally more fertile and better watered.

The hilly Vagad region, home to the cities of Dungarpur and Banswara lies in southernmost Rajasthan, on the border with Gujarat and Madhya Pradesh.

Problem: From July to September 1989, Voyager 2 discovered six moons of Neptune. Of these, the irregularly shaped Proteus is notable for being as large as a body of its density can be without being pulled into a spherical shape by its own gravity. Although the second-most-massive Neptunian moon, it is only 0.25% the mass of Triton. Neptune's innermost four moonsNaiad, Thalassa, Despina and Galateaorbit close enough to be within Neptune's rings. The next-farthest out, Larissa, was originally discovered in 1981 when it had occulted a star. This occultation had been attributed to ring arcs, but when Voyager 2 observed Neptune in 1989, Larissa was found to have caused it. Five new irregular moons discovered between 2002 and 2003 were announced in 2004. A new moon and the smallest yet, S/2004 N 1, was found in 2013. Because Neptune was the Roman god of the sea, Neptune's moons have been named after lesser sea gods.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Countrywide, sued by California Attorney General Jerry Brown for "unfair business practices" and "false advertising" was making high cost mortgages "to homeowners with weak credit, adjustable rate mortgages (ARMs) that allowed homeowners to make interest-only payments". When housing prices decreased, homeowners in ARMs then had little incentive to pay their monthly payments, since their home equity had disappeared. This caused Countrywide's financial condition to deteriorate, ultimately resulting in a decision by the Office of Thrift Supervision to seize the lender.
What type mortgages allowed homeowners to make interest-only payments?
A: adjustable rate mortgages (ARMs)

Context and question: By 1976, Queen were back in the studio recording A Day at the Races, which is often regarded as a sequel album to A Night at the Opera. It again borrowed the name of a Marx Brothers movie, and its cover was similar to that of A Night at the Opera, a variation on the same Queen Crest. The most recognisable of the Marx Brothers, Groucho Marx, invited Queen to visit him in his Los Angeles home in March 1977; there the band thanked him in person, and performed "'39" a cappella. Musically, A Day at the Races was by both fans' and critics' standards a strong effort, reaching number one in the UK and Japan, and number five in the US. The major hit on the album was "Somebody to Love", a gospel-inspired song in which Mercury, May, and Taylor multi-tracked their voices to create a 100-voice gospel choir. The song went to number two in the UK, and number thirteen in the US. The album also featured one of the band's heaviest songs, May's "Tie Your Mother Down", which became a staple of their live shows.
Which Queen members layered their voices on Somebody to Love?
Answer: Mercury, May, and Taylor

Question: To begin with, England had no permanent home stadium. They joined FIFA in 1906 and played their first ever games against countries other than the Home Nations on a tour of Central Europe in 1908. Wembley Stadium was opened in 1923 and became their home ground. The relationship between England and FIFA became strained, and this resulted in their departure from FIFA in 1928, before they rejoined in 1946. As a result, they did not compete in a World Cup until 1950, in which they were beaten in a 10 defeat by the United States, failing to get past the first round in one of the most embarrassing defeats in the team's history.
Is there an answer to this question: England played against countries besides the Home Nations for the first time in what year?

Answer: 1908

Question: The history of emotions has become an increasingly popular topic recently, with some scholars arguing that it is an essential category of analysis, not unlike class, race, or gender. Historians, like other social scientists, assume that emotions, feelings and their expressions are regulated in different ways by both different cultures and different historical times, and constructivist school of history claims even that some sentiments and meta-emotions, for example Schadenfreude, are learnt and not only regulated by culture. Historians of emotion trace and analyse the changing norms and rules of feeling, while examining emotional regimes, codes, and lexicons from social, cultural or political history perspectives. Others focus on the history of medicine, science or psychology. What somebody can and may feel (and show) in a given situation, towards certain people or things, depends on social norms and rules. It is thus historically variable and open to change. Several research centers have opened in the past few years in Germany, England, Spain, Sweden and Australia.
Is there an answer to this question: Along with Germany, England, Spain and Australia, where has a research center on the history of emotions recently opened?

Answer:
Sweden
