Article: Houston's highway system has a hub-and-spoke freeway structure serviced by multiple loops. The innermost loop is Interstate 610, which encircles downtown, the medical center, and many core neighborhoods with around a 8-mile (13 km) diameter. Beltway 8 and its freeway core, the Sam Houston Tollway, form the middle loop at a diameter of roughly 23 miles (37 km). A proposed highway project, State Highway 99 (Grand Parkway), will form a third loop outside of Houston, totaling 180 miles in length and making an almost-complete circumference, with the exception of crossing the ship channel. As of June 2014, two of eleven segments of State Highway 99 have been completed to the west of Houston, and three northern segments, totaling 38 miles, are actively under construction and scheduled to open to traffic late in 2015. In addition to the Sam Houston Tollway loop mentioned above, the Harris County Toll Road Authority currently operates four spoke tollways: The Katy Managed Lanes of Interstate 10, the Hardy Toll Road, the Westpark Tollway, and the Fort Bend Parkway Extension. Other spoke roads either planned or under construction include Crosby Freeway, and the future Alvin Freeway.

Question: What is the type of freeway system that serves Houston?
Ans: hub-and-spoke


Article: On July 5, 1779, 2,600 loyalists and British regulars under General William Tryon, governor of New York, landed in New Haven Harbor and raided the 3,500-person town. A militia of Yale students had been prepping for battle, and former Yale president and Yale Divinity School professor Naphtali Daggett rode out to confront the Redcoats. Yale president Ezra Stiles recounted in his diary that while he moved furniture in anticipation of battle, he still couldn't quite believe the revolution had begun. New Haven was not torched as the invaders did with Danbury in 1777, or Fairfield and Norwalk a week after the New Haven raid, so many of the town's colonial features were preserved.

Question: Who was the president of Yale at the time of the attack?
Ans: Ezra Stiles

Article: Two Polish friends in Paris were also to play important roles in Chopin's life there. His fellow student at the Warsaw Conservatory, Julian Fontana, had originally tried unsuccessfully to establish himself in England; Albert Grzymała, who in Paris became a wealthy financier and society figure, often acted as Chopin's adviser and "gradually began to fill the role of elder brother in [his] life." Fontana was to become, in the words of Michałowski and Samson, Chopin's "general factotum and copyist".

Ans:
England
