The location at the mouth of the Hudson River, which feeds into a naturally sheltered harbor and then into the Atlantic Ocean, has helped the city grow in significance as a trading port.

Problem: The Umayyad Caliphate (Arabic: , trans. Al-Khilafat al-umawiyya) was the second of the four major Islamic caliphates established after the death of Muhammad. This caliphate was centered on the Umayyad dynasty (Arabic: , al-Umawiyyun, or , Banu Umayya, "Sons of Umayya"), hailing from Mecca. The Umayyad family had first come to power under the third caliph, Uthman ibn Affan (r. 644656), but the Umayyad regime was founded by Muawiya ibn Abi Sufyan, long-time governor of Syria, after the end of the First Muslim Civil War in 661 CE/41 AH. Syria remained the Umayyads' main power base thereafter, and Damascus was their capital. The Umayyads continued the Muslim conquests, incorporating the Caucasus, Transoxiana, Sindh, the Maghreb and the Iberian Peninsula (Al-Andalus) into the Muslim world. At its greatest extent, the Umayyad Caliphate covered 15 million km2 (5.79 million square miles), making it the largest empire (in terms of area - not in terms of population) the world had yet seen, and the fifth largest ever to exist.
Who was the third caliph?

Answer: Uthman ibn Affan

Context and question: Near the end of the first decade of the double-Bills' guidance, the Cubs won the NL pennant in 1929 and then achieved the unusual feat of winning a pennant every three years, following up the 1929 flag with league titles in 1932, 1935, and 1938. Unfortunately, their success did not extend to the Fall Classic, as they fell to their AL rivals each time. The '32 series against the Yankees featured Babe Ruth's "called shot" at Wrigley Field in Game 3. There were some historic moments for the Cubs as well; In 1930, Hack Wilson, one of the top home run hitters in the game, had one of the most impressive seasons in MLB history, hitting 56 home runs and establishing the current runs-batted-in record of 191. That 1930 club, which boasted six eventual Hall of Famers (Wilson, Gabby Hartnett, Rogers Hornsby, George "High Pockets" Kelly, Kiki Cuyler and manager Joe McCarthy) established the current team batting average record of .309. In 1935 the Cubs claimed the pennant in thrilling fashion, winning a record 21 games in a row in September. The '38 club saw Dizzy Dean lead the team's pitching staff and provided a historic moment when they won a crucial late-season game at Wrigley Field over the Pittsburgh Pirates with a walk-off home run by Gabby Hartnett, which became known in baseball lore as "The Homer in the Gloamin'".
What year did Hack Wilson have one of the most impressive seasons in MLB history?
Answer: 1930

Question: One philosophical school which has historically had a close relationship with process philosophy is American pragmatism. Whitehead himself thought highly of William James and John Dewey, and acknowledged his indebtedness to them in the preface to Process and Reality. Charles Hartshorne (along with Paul Weiss) edited the collected papers of Charles Sanders Peirce, one of the founders of pragmatism. Noted neopragmatist Richard Rorty was in turn a student of Hartshorne. Today, Nicholas Rescher is one example of a philosopher who advocates both process philosophy and pragmatism.
Is there an answer to this question: What pragmatists did Whitehead not acknowledge in the preface to "Process and Reality"?

Answer: unanswerable

Question: The Ismailis differ from Twelvers because they had living imams for centuries after the last Twelver Imam went into concealment. They followed Isma'il ibn Jafar, elder brother of Musa al-Kadhim, as the rightful Imam after his father Ja'far al-Sadiq. The Ismailis believe that whether Imam Ismail did or did not die before Imam Ja'far, he had passed on the mantle of the imamate to his son Muhammad ibn Ismail as the next imam. Thus, their line of imams is as follows (the years of their individual imamats during the Common Era are given in brackets):
Is there an answer to this question: What did Imam Ismail pass on to his son?

Answer:
mantle of the imamate
