Here is a question about this article: In 1953, Korolev was given the go-ahead to develop the R-7 Semyorka rocket, which represented a major advance from the German design. Although some of its components (notably boosters) still resembled the German G-4, the new rocket incorporated staged design, a completely new control system, and a new fuel. It was successfully tested on August 21, 1957 and became the world's first fully operational ICBM the following month. It would later be used to launch the first satellite into space, and derivatives would launch all piloted Soviet spacecraft.
What is the answer to this question: Who began developing the  R-7 Semyorka rocket?
****
So... Korolev

Operation Torch also served as a valuable training ground for Eisenhower's combat command skills; during the initial phase of Generalfeldmarschall Erwin Rommel's move into the Kasserine Pass, Eisenhower created some confusion in the ranks by some interference with the execution of battle plans by his subordinates. He also was initially indecisive in his removal of Lloyd Fredendall, commanding U.S. II Corps. He became more adroit in such matters in later campaigns. In February 1943, his authority was extended as commander of AFHQ across the Mediterranean basin to include the British Eighth Army, commanded by General Sir Bernard Montgomery. The Eighth Army had advanced across the Western Desert from the east and was ready for the start of the Tunisia Campaign. Eisenhower gained his fourth star and gave up command of ETOUSA to become commander of NATOUSA.

What was Rommel's rank?
Answer: Generalfeldmarschall


Problem: In the 1970s the US Law Enforcement Assistance Administration (LEAA) found a reduction of 10% to 13% in Washington, D.C.'s violent crime rate during DST. However, the LEAA did not filter out other factors, and it examined only two cities and found crime reductions only in one and only in some crime categories; the DOT decided it was "impossible to conclude with any confidence that comparable benefits would be found nationwide". Outdoor lighting has a marginal and sometimes even contradictory influence on crime and fear of crime.
In what decade did the LEAA conduct their investigation of crime and DST?
The answer is the following: 1970s


Input: Article: A standard adult football match consists of two periods of 45 minutes each, known as halves. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called additional time in FIFA documents, but is most commonly referred to as stoppage time or injury time, while loss time can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. The referee alone signals the end of the match. In matches where a fourth official is appointed, toward the end of the half the referee signals how many minutes of stoppage time he intends to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa. Trailing 1–0 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over. The same law also states that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.

Now answer this question: How long are each period in a standard football match?

Output:
45
