The problem: Answer a question about this article:
Expansion of Highbury was restricted because the East Stand had been designated as a Grade II listed building and the other three stands were close to residential properties. These limitations prevented the club from maximising matchday revenue during the 1990s and first decade of the 21st century, putting them in danger of being left behind in the football boom of that time. After considering various options, in 2000 Arsenal proposed building a new 60,361-capacity stadium at Ashburton Grove, since named the Emirates Stadium, about 500 metres south-west of Highbury. The project was initially delayed by red tape and rising costs, and construction was completed in July 2006, in time for the start of the 200607 season. The stadium was named after its sponsors, the airline company Emirates, with whom the club signed the largest sponsorship deal in English football history, worth around 100 million; some fans referred to the ground as Ashburton Grove, or the Grove, as they did not agree with corporate sponsorship of stadium names. The stadium will be officially known as Emirates Stadium until at least 2028, and the airline will be the club's shirt sponsor until the end of the 201819 season. From the start of the 201011 season on, the stands of the stadium have been officially known as North Bank, East Stand, West Stand and Clock end.
When did Arsenal offer a plan to build a new stadium at Ashburton Grove?

The answer: 2000

Northwestern was elected to the Association of American Universities in 1917 and remains a research university with "very high" research activity. Northwestern's schools of management, engineering, and communication are among the most academically productive in the nation. Northwestern received $550 million in research funding in 2014. Northwestern supports nearly 1,500 research laboratories across two campuses, predominately in the medical and biological sciences. Through the Innovation and New Ventures Office (INVO), Northwestern researchers disclosed 247 inventions, filed 270 patents applications, received 81 foreign and US patents, started 12 companies, and generated $79.8 million in licensing revenue in 2013. The bulk of revenue has come from a patent on pregabalin, a synthesized organic molecule discovered by chemistry professor Richard Silverman, which ultimately was marketed as Lyrica, a drug sold by Pfizer, to combat epilepsy, neuropathic pain, and fibromyalgia. INVO has been involved in creating a number of centers, including the Center for Developmental Therapeutics (CDT) and the Center for Device Development (CD2). It has also helped form over 50 Northwestern startup companies based on Northwestern technologies.
Who discovered the drug that was ultimately marketed as Lyrica?
****
The answer: chemistry professor Richard Silverman

The history of the area that now constitutes Himachal Pradesh dates back to the time when the Indus valley civilisation flourished between 2250 and 1750 BCE. Tribes such as the Koilis, Halis, Dagis, Dhaugris, Dasa, Khasas, Kinnars, and Kirats inhabited the region from the prehistoric era. During the Vedic period, several small republics known as "Janapada" existed which were later conquered by the Gupta Empire. After a brief period of supremacy by King Harshavardhana, the region was once again divided into several local powers headed by chieftains, including some Rajput principalities. These kingdoms enjoyed a large degree of independence and were invaded by Delhi Sultanate a number of times. Mahmud Ghaznavi conquered Kangra at the beginning of the 10th century. Timur and Sikander Lodi also marched through the lower hills of the state and captured a number of forts and fought many battles. Several hill states acknowledged Mughal suzerainty and paid regular tribute to the Mughals.
When did Mahmud Ghanznavi conquer Kangara?
