Article: Defining exactly what section of a DNA sequence comprises a gene is difficult. Regulatory regions of a gene such as enhancers do not necessarily have to be close to the coding sequence on the linear molecule because the intervening DNA can be looped out to bring the gene and its regulatory region into proximity. Similarly, a gene's introns can be much larger than its exons. Regulatory regions can even be on entirely different chromosomes and operate in trans to allow regulatory regions on one chromosome to come in contact with target genes on another chromosome.

Question: What is an example of a regulatory region of a gene that does not have to close to the coding sequence?
Ans: enhancers


Article: The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.

Question: Noyce's IC was made up of what material?
Ans: silicon


Article: Since then, the Bronx has always supported the Democratic Party's nominee for President, starting with a vote of 2-1 for the unsuccessful Al Smith in 1928, followed by four 2-1 votes for the successful Franklin D. Roosevelt. (Both had been Governors of New York, but Republican former Gov. Thomas E. Dewey won only 28% of the Bronx's vote in 1948 against 55% for Pres. Harry Truman, the winning Democrat, and 17% for Henry A. Wallace of the Progressives. It was only 32 years earlier, by contrast, that another Republican former Governor who narrowly lost the Presidency, Charles Evans Hughes, had won 42.6% of the Bronx's 1916 vote against Democratic President Woodrow Wilson's 49.8% and Socialist candidate Allan Benson's 7.3%.)

Question: How much of the Bronx's vote in 1948 did Truman get?
Ans: 55%


Article: It was ten years after the inception of the youth program, La Masia, when the young players began to graduate and play for their first team. One of the first graduates, who would later earn international acclaim, was previous Barcelona coach Pep Guardiola. Under Cruyff's guidance, Barcelona won four consecutive La Liga titles from 1991 to 1994. They beat Sampdoria in both the 1989 UEFA Cup Winners' Cup final and the 1992 European Cup final at Wembley, with a free kick goal from Dutch international Ronald Koeman. They also won a Copa del Rey in 1990, the European Super Cup in 1992 and three Supercopa de España trophies. With 11 trophies, Cruyff became the club's most successful manager at that point. He also became the club's longest consecutive serving manager, serving eight years. Cruyff's fortune was to change, and, in his final two seasons, he failed to win any trophies and fell out with president Núñez, resulting in his departure. On the legacy of Cruyff's football philosophy and the passing style of play he introduced to the club, future coach of Barcelona Pep Guardiola would state, "Cruyff built the cathedral, our job is to maintain and renovate it."

Question: For how many years was Cruyff manager for Barcelona?
Ans:
eight
