Question: How old was Jennie Jerome when her granddaughter Lady Eden was born? Passage:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (1880–1947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (1885–1941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 1886–87, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.

Question: Who was the president of University of Tennessee when Mike Smithson was a student? Passage:After attending the University of Tennessee, Smithson was selected by the Red Sox in the fifth round of the 1976 Major League Baseball Draft. During the course of his seven-year minor league apprenticeship, he participated in the longest baseball game in history between the Pawtucket Red Sox and Rochester Red Wings during the 1981 season. During the early morning hours of Sunday, April 19, 1981, he worked the full 15th, 16th and 17th innings, and got two outs in the 18th inning before turning the ball over to Win Remmerswaal. Smithson allowed two hits and three bases on balls in 3 innings pitched—but no runs. The game was suspended after 32 innings, and resumed June 23; Smithson's PawSox won it in the bottom of the 33rd frame.

Question: What oceans are adjacent to the Arabian Sea? Passage:Bhaja Caves is a group of 22 rock-cut caves dating back to the 2nd century BC located in the city of Pune, India. The caves are 400 feet above the village of Bhaja, on an important ancient trade route running from the Arabian Sea eastward into the Deccan Plateau (the division between North India and South India). The inscriptions and the cave temple are protected as a Monument of National Importance, by the Archaeological Survey of India per Notification No. 2407-A. It belongs to the Hinayana Buddhism sect in Maharashtra. The caves have a number of stupas, one of their significant features. The most prominent excavation is its chaitya (or chaityagrha - Cave XII), a good example of the early development of this form from wooden architecture, with a vaulted horseshoe ceiling. Its vihara (Cave XVIII) has a pillared verandah in front and is adorned with unique reliefs. These caves are notable for their indications of the awareness of wooden architecture. The carvings prove that tabla – a percussion instrument – was used in India for at least 2300 years, disproving the centuries-held belief that the tabla was introduced to India by outsiders or from Turko-Arab. The carving shows a woman playing tabla and another woman, performing dance.
