Problem: Please answer a question about the following article about Premier League:
One significant feature of the Premier League in the mid-2000s was the dominance of the so-called "Big Four" clubs: Arsenal, Chelsea, Liverpool and Manchester United. During this decade, and particularly from 2002 to 2009, they dominated the top four spots, which came with UEFA Champions League qualification, taking all top four places in 5 out of 6 seasons from 200304 to 200809 inclusive, with Arsenal going as far as winning the league without losing a single game in 200304, the only time it has ever happened in the Premier League. In May 2008 Kevin Keegan stated that "Big Four" dominance threatened the division, "This league is in danger of becoming one of the most boring but great leagues in the world." Premier League chief executive Richard Scudamore said in defence: "There are a lot of different tussles that go on in the Premier League depending on whether you're at the top, in the middle or at the bottom that make it interesting."
Which of the "Big Four" teams did not lose a single game in the 2003-04 season?
A: Arsenal
Problem: Please answer a question about the following article about Tajikistan:
It was temporarily under the control of the Tibetan empire and Chinese from 650680 and then under the control of the Umayyads in 710. The Samanid Empire, 819 to 999, restored Persian control of the region and enlarged the cities of Samarkand and Bukhara (both cities are today part of Uzbekistan) which became the cultural centers of Iran and the region was known as Khorasan. The Kara-Khanid Khanate conquered Transoxania (which corresponds approximately with modern-day Uzbekistan, Tajikistan, southern Kyrgyzstan and southwest Kazakhstan) and ruled between 9991211. Their arrival in Transoxania signaled a definitive shift from Iranian to Turkic predominance in Central Asia, but gradually the Kara-khanids became assimilated into the Perso-Arab Muslim culture of the region.
When was the region under Tibetan empire and the CHinese?
A: 650680
Problem: Please answer a question about the following article about Pharmaceutical industry:
In 1911 arsphenamine, the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of the Institute of Experimental Therapy in Berlin. The drug was given the commercial name Salvarsan. Ehrlich, noting both the general toxicity of arsenic and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]
Bacterial infections could be treated with medicines containing what kind of dye?
A:
arsenic
