Problem: Uranium:

Two major types of atomic bombs were developed by the United States during World War II: a uranium-based device (codenamed "Little Boy") whose fissile material was highly enriched uranium, and a plutonium-based device (see Trinity test and "Fat Man") whose plutonium was derived from uranium-238. The uranium-based Little Boy device became the first nuclear weapon used in war when it was detonated over the Japanese city of Hiroshima on 6 August 1945. Exploding with a yield equivalent to 12,500 tonnes of TNT, the blast and thermal wave of the bomb destroyed nearly 50,000 buildings and killed approximately 75,000 people (see Atomic bombings of Hiroshima and Nagasaki). Initially it was believed that uranium was relatively rare, and that nuclear proliferation could be avoided by simply buying up all known uranium stocks, but within a decade large deposits of it were discovered in many places around the world.

What was the codename of the plutonium-based bomb created in the Second World War?
---
A: Fat Man


Problem: The console was originally planned for a global release through November, but at the start of September the release in Europe and the rest of the world was delayed until March. With it being a somewhat last-minute delay, some companies had taken deposits for pre-orders, at which Sony informed customers that they were eligible for full refunds or could continue the pre-order. On January 24, 2007, Sony announced that PlayStation 3 would go on sale on March 23, 2007, in Europe, Australia, the Middle East, Africa and New Zealand. The system sold about 600,000 units in its first two days. On March 7, 2007, the 60 GB PlayStation 3 launched in Singapore with a price of S$799. The console was launched in South Korea on June 16, 2007, as a single version equipped with an 80 GB hard drive and IPTV.
Instead of November, for what month of the following year was the release rescheduled?

Answer: March


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Houston has mild winters in contrast to most areas of the United States. In January, the normal mean temperature at Intercontinental Airport is 53.1 °F (11.7 °C), while that station has an average of 13 days with a low at or below freezing. Snowfall is rare. Recent snow events in Houston include a storm on December 24, 2004 when one inch (2.5 cm) of snow accumulated in parts of the metro area. Falls of at least one inch on both December 10, 2008 and December 4, 2009 marked the first time measurable snowfall had occurred in two consecutive years in the city's recorded history. The coldest temperature officially recorded in Houston was 5 °F (−15 °C) on January 18, 1940. Houston has historically received an ample amount of rainfall, averaging about 49.8 in (1,260 mm) annually per 1981–2010 normals. Localized flooding often occurs, owing to the extremely flat topography and widespread typical clay-silt prairie soils, which do not drain quickly.
What kind of winter weather does Houston have?
A: mild winters


Context and question: The influence of cubism extended to other artistic fields, outside painting and sculpture. In literature, the written works of Gertrude Stein employ repetition and repetitive phrases as building blocks in both passages and whole chapters. Most of Stein's important works utilize this technique, including the novel The Making of Americans (1906–08). Not only were they the first important patrons of Cubism, Gertrude Stein and her brother Leo were also important influences on Cubism as well. Picasso in turn was an important influence on Stein's writing.
Who was not influencial on Cubism?
Answer: unanswerable


Question: The FBI is near-impenetrable, with applicants intensely scrutinized and assessed over an extended period. To apply to become an FBI agent, one must be between the ages of 23 and 37. Due to the decision in Robert P. Isabella v. Department of State and Office of Personnel Management, 2008 M.S.P.B. 146, preference-eligible veterans may apply after age 37. In 2009, the Office of Personnel Management issued implementation guidance on the Isabella decision. The applicant must also hold American citizenship, be of high moral character, have a clean record, and hold at least a four-year bachelor's degree. At least three years of professional work experience prior to application is also required. All FBI employees require a Top Secret (TS) security clearance, and in many instances, employees need a TS/SCI (Top Secret/Sensitive Compartmented Information) clearance. To obtain a security clearance, all potential FBI personnel must pass a series of Single Scope Background Investigations (SSBI), which are conducted by the Office of Personnel Management. Special Agents candidates also have to pass a Physical Fitness Test (PFT), which includes a 300-meter run, one-minute sit-ups, maximum push-ups, and a 1.5-mile (2.4 km) run. Personnel must pass a polygraph test with questions including possible drug use. Applicants who fail polygraphs may not gain employment with the FBI.

Question: Adolescence marks a rapid change in one's role within a family. Young children tend to assert themselves forcefully, but are unable to demonstrate much influence over family decisions until early adolescence, when they are increasingly viewed by parents as equals. The adolescent faces the task of increasing independence while preserving a caring relationship with his or her parents. When children go through puberty, there is often a significant increase in parent–child conflict and a less cohesive familial bond. Arguments often concern minor issues of control, such as curfew, acceptable clothing, and the adolescent's right to privacy, which adolescents may have previously viewed as issues over which their parents had complete authority. Parent-adolescent disagreement also increases as friends demonstrate a greater impact on one another, new influences on the adolescent that may be in opposition to parents' values. Social media has also played an increasing role in adolescent and parent disagreements. While parents never had to worry about the threats of social media in the past, it has become a dangerous place for children. While adolescents strive for their freedoms, the unknowns to parents of what their child is doing on social media sites is a challenging subject, due to the increasing amount of predators on social media sites. Many parents have very little knowledge of social networking sites in the first place and this further increases their mistrust. An important challenge for the parent–adolescent relationship is to understand how to enhance the opportunities of online communication while managing its risks. Although conflicts between children and parents increase during adolescence, these are just relatively minor issues. Regarding their important life issues, most adolescents still share the same attitudes and values as their parents.
Is there an answer to this question: During what stage of development is there increased parent-child conflict and a less cohesive familial bond?

Answer:
puberty
