Problem: Gene:

The most common source of new genes in eukaryotic lineages is gene duplication, which creates copy number variation of an existing gene in the genome. The resulting genes (paralogs) may then diverge in sequence and in function. Sets of genes formed in this way comprise a gene family. Gene duplications and losses within a family are common and represent a major source of evolutionary biodiversity. Sometimes, gene duplication may result in a nonfunctional copy of a gene, or a functional copy may be subject to mutations that result in loss of function; such nonfunctional genes are called pseudogenes.:7.6

What are functional copies of a gene which have a loss of function due to mutation called?
---
A: pseudogenes

Problem: Beyonce has received numerous awards. As a solo artist she has sold over 15 million albums in the US, and over 118 million records worldwide (a further 60 million additionally with Destiny's Child), making her one of the best-selling music artists of all time. The Recording Industry Association of America (RIAA) listed Beyonce as the top certified artist of the 2000s, with a total of 64 certifications. Her songs "Crazy in Love", "Single Ladies (Put a Ring on It)", "Halo", and "Irreplaceable" are some of the best-selling singles of all time worldwide. In 2009, The Observer named her the Artist of the Decade and Billboard named her the Top Female Artist and Top Radio Songs Artist of the Decade. In 2010, Billboard named her in their "Top 50 R&B/Hip-Hop Artists of the Past 25 Years" list at number 15. In 2012 VH1 ranked her third on their list of the "100 Greatest Women in Music". Beyonce was the first female artist to be honored with the International Artist Award at the American Music Awards. She has also received the Legend Award at the 2008 World Music Awards and the Billboard Millennium Award at the 2011 Billboard Music Awards.
How many records has she sold with Destiny's Child?

A: unanswerable

Context and question: Protestantism also spread from the German lands into France, where the Protestants were nicknamed Huguenots. Calvin continued to take an interest in the French religious affairs from his base in Geneva. He regularly trained pastors to lead congregations there. Despite heavy persecution, the Reformed tradition made steady progress across large sections of the nation, appealing to people alienated by the obduracy and the complacency of the Catholic establishment. French Protestantism came to acquire a distinctly political character, made all the more obvious by the conversions of nobles during the 1550s. This established the preconditions for a series of conflicts, known as the French Wars of Religion. The civil wars gained impetus with the sudden death of Henry II of France in 1559. Atrocity and outrage became the defining characteristics of the time, illustrated at their most intense in the St. Bartholomew's Day massacre of August 1572, when the Roman Catholic party annihilated between 30,000 and 100,000 Huguenots across France. The wars only concluded when Henry IV of France issued the Edict of Nantes, promising official toleration of the Protestant minority, but under highly restricted conditions. Roman Catholicism remained the official state religion, and the fortunes of French Protestants gradually declined over the next century, culminating in Louis XIV's Edict of Fontainebleau which revoked the Edict of Nantes and made Roman Catholicism the sole legal religion once again. In response to the Edict of Fontainebleau, Frederick William I, Elector of Brandenburg declared the Edict of Potsdam, giving free passage to Huguenot refugees. In the late 17th century many Huguenots fled to England, the Netherlands, Prussia, Switzerland, and the English and Dutch overseas colonies. A significant community in France remained in the Cevennes region.
When were French nobles converted to Protestantism?
Answer: the 1550s

Question: In 1972, the French physicist Francis Perrin discovered fifteen ancient and no longer active natural nuclear fission reactors in three separate ore deposits at the Oklo mine in Gabon, West Africa, collectively known as the Oklo Fossil Reactors. The ore deposit is 1.7 billion years old; then, uranium-235 constituted about 3% of the total uranium on Earth. This is high enough to permit a sustained nuclear fission chain reaction to occur, provided other supporting conditions exist. The capacity of the surrounding sediment to contain the nuclear waste products has been cited by the U.S. federal government as supporting evidence for the feasibility to store spent nuclear fuel at the Yucca Mountain nuclear waste repository.
Is there an answer to this question: Where in the United States is there no nuclear waste repository?

Answer: unanswerable

Problem: Alloy:

Iron is usually found as iron ore on Earth, except for one deposit of native iron in Greenland, which was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which is much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle East, people began alloying copper with zinc to form brass. Ancient civilizations took into account the mixture and the various properties it produced, such as hardness, toughness and melting point, under various conditions of temperature and work hardening, developing much of the information contained in modern alloy phase diagrams. Arrowheads from the Chinese Qin dynasty (around 200 BC) were often constructed with a hard bronze-head, but a softer bronze-tang, combining the alloys to prevent both dulling and breaking during use.

Where is the only iron deposit on earth?

A:
Greenland
