Input: Question: How old was Jennie Jerome when her granddaughter Lady Eden was born? Passage 1:On its way back to Macedonia, the funerary cart with Alexander's body was met in Syria by one of Alexander's generals, the future ruler Ptolemy I Soter. In late 322 or early 321 BC Ptolemy diverted the body to Egypt where it was interred in Memphis, Egypt. In the late 4th or early 3rd century BC Alexander's body was transferred from the Memphis tomb to Alexandria for reburial (by Ptolemy Philadelphus in c. 280 BC, according to Pausanias). Later Ptolemy Philopator placed Alexander's body in Alexandria's communal mausoleum. Shortly after the death of Cleopatra, Alexander's resting place was visited by Augustus, who is said to have placed flowers on the tomb and a golden diadem upon Alexander's head. By the 4th century AD the resting place of Alexander was no longer known; later authors, such as Ibn 'Abd al-Hakam, Al-Masudi and Leo the African, report having seen Alexander's tomb. Leo the African in 1491 and George Sandys in 1611 reportedly saw the tomb in Alexandria. According to one legend, the body lies in a crypt beneath an early Christian church.
 Passage 2:Masimo is an American manufacturer of noninvasive patient monitoring technologies based in Irvine, California. The company sells more pulse oximetry to hospitals than any other company. Masimo was founded in 1989 by electrical engineer Joe Kiani, who was later joined by fellow engineer Mohamed Diab. Masimo invented measure-through motion and low perfusion pulse oximetry, known as Masimo SET (Signal Extraction Technology). Masimo has been recognized for its intellectual property and for being one of the most innovative companies in the medical device industry. The company went public in 2007 and is currently traded on the NASDAQ stock exchange under the symbol MASI. In 2011, Forbes named Masimo to its list of top 20 public companies under a billion dollars in revenue, based on earnings growth, sales growth, and return on equity. In 2012, Joe Kiani, founder, CEO and Chairman of the Board was named the Ernst & Young National Entrepreneur of the Year - 2012 Life Sciences Award Winner. Kiani was recognized for "revolutionizing the health care industry by taking risks to create and commercialize noninvasive patient monitoring devices, which include an array of sensors that lead to improved accuracy, a reduction in the overall number of false readings, and ultimately, reduced cost of care."
 Passage 3: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.
