Problem: Lee's childhood friend, author Truman Capote, wrote on the dust jacket of the first edition, "Someone rare has written this very fine first novel: a writer with the liveliest sense of life, and the warmest, most authentic sense of humor. A touching book; and so funny, so likeable." This comment has been construed to suggest that Capote wrote the book or edited it heavily. In 2003, a Tuscaloosa newspaper quoted Capote's biological father, Archulus Persons, as claiming that Capote had written "almost all" of the book. In 2006, a Capote letter was donated to Monroeville's literary heritage museum; in a letter to a neighbor in Monroeville in 1959, Capote mentioned that Lee was writing a book that was to be published soon. Extensive notes between Lee and her editor at Lippincott also refute the rumor of Capote's authorship. Lee's older sister, Alice, responded to the rumor, saying: "That's the biggest lie ever told."
Who was speculated to have wrote the book instead of Harper Lee?

Answer: Truman Capote

Context and question: Since chlorinated hydrocarbon pesticides dissolve in fats and are not excreted, organisms tend to retain them almost indefinitely. Biological magnification is the process whereby these chlorinated hydrocarbons (pesticides) are more concentrated at each level of the food chain. Among marine animals, pesticide concentrations are higher in carnivorous fishes, and even more so in the fish-eating birds and mammals at the top of the ecological pyramid. Global distillation is the process whereby pesticides are transported from warmer to colder regions of the Earth, in particular the Poles and mountain tops. Pesticides that evaporate into the atmosphere at relatively high temperature can be carried considerable distances (thousands of kilometers) by the wind to an area of lower temperature, where they condense and are carried back to the ground in rain or snow.
How far do fish-eating birds need to fly for a meal?
Answer: unanswerable

Question: In 2005, seventeen countries produced concentrated uranium oxides, with Canada (27.9% of world production) and Australia (22.8%) being the largest producers and Kazakhstan (10.5%), Russia (8.0%), Namibia (7.5%), Niger (7.4%), Uzbekistan (5.5%), the United States (2.5%), Argentina (2.1%), Ukraine (1.9%) and China (1.7%) also producing significant amounts. Kazakhstan continues to increase production and may have become the world's largest producer of uranium by 2009 with an expected production of 12,826 tonnes, compared to Canada with 11,100 t and Australia with 9,430 t. In the late 1960s, UN geologists also discovered major uranium deposits and other rare mineral reserves in Somalia. The find was the largest of its kind, with industry experts estimating the deposits at over 25% of the world's then known uranium reserves of 800,000 tons.
Is there an answer to this question: What percentage of world uranium oxide production isn't produced by Argentina?

Answer: unanswerable

Question: 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 10 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.
Is there an answer to this question: Who has no influence on how long stoppage time can go on for?

Answer:
unanswerable
