Problem: Daylight saving time:

Start and end dates vary with location and year. Since 1996 European Summer Time has been observed from the last Sunday in March to the last Sunday in October; previously the rules were not uniform across the European Union. Starting in 2007, most of the United States and Canada observe DST from the second Sunday in March to the first Sunday in November, almost two-thirds of the year. The 2007 US change was part of the Energy Policy Act of 2005; previously, from 1987 through 2006, the start and end dates were the first Sunday in April and the last Sunday in October, and Congress retains the right to go back to the previous dates now that an energy-consumption study has been done. Proponents for permanently retaining November as the month for ending DST point to Halloween as a reason to delay the change in order to allow extra daylight for the evening of October 31.

What government body is allowed to change the DST policy in the United States back to the dates observed from 1987 to 2006?
---
A: Congress


Problem: The HMWSSB regulates rainwater harvesting, sewerage services and water supply, which is sourced from several dams located in the suburbs. In 2005, the HMWSSB started operating a 116-kilometre-long (72 mi) water supply pipeline from Nagarjuna Sagar Dam to meet increasing demand. The Telangana Southern Power Distribution Company Limited manages electricity supply. As of October 2014, there were 15 fire stations in the city, operated by the Telangana State Disaster and Fire Response Department. The government-owned India Post has five head post offices and many sub-post offices in Hyderabad, which are complemented by private courier services.
What dam began to provide water to Hyderabad in 2005?

Answer: Nagarjuna Sagar Dam


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Muslim rule started in parts of north India in the 13th century when the Delhi Sultanate was founded in 1206 CE by the Central Asian Turks. The Delhi Sultanate ruled the major part of northern India in the early 14th century, but declined in the late 14th century when several powerful Hindu states such as the Vijayanagara Empire, Gajapati Kingdom, Ahom Kingdom, as well as Rajput dynasties and states, such as Mewar dynasty, emerged. The 15th century saw the emergence of Sikhism. In the 16th century, Mughals came from Central Asia and gradually covered most of India. The Mughal Empire suffered a gradual decline in the early 18th century, which provided opportunities for the Maratha Empire, Sikh Empire and Mysore Kingdom to exercise control over large areas of the subcontinent.
What belief system began in the 15th century?
A: Sikhism


Context and question: In 1968 Ronald Melzack and Kenneth Casey described pain in terms of its three dimensions: "sensory-discriminative" (sense of the intensity, location, quality and duration of the pain), "affective-motivational" (unpleasantness and urge to escape the unpleasantness), and "cognitive-evaluative" (cognitions such as appraisal, cultural values, distraction and hypnotic suggestion). They theorized that pain intensity (the sensory discriminative dimension) and unpleasantness (the affective-motivational dimension) are not simply determined by the magnitude of the painful stimulus, but "higher" cognitive activities can influence perceived intensity and unpleasantness. Cognitive activities "may affect both sensory and affective experience or they may modify primarily the affective-motivational dimension. Thus, excitement in games or war appears to block both dimensions of pain, while suggestion and placebos may modulate the affective-motivational dimension and leave the sensory-discriminative dimension relatively undisturbed." (p. 432) The paper ends with a call to action: "Pain can be treated not only by trying to cut down the sensory input by anesthetic block, surgical intervention and the like, but also by influencing the motivational-affective and cognitive factors as well." (p. 435)
How many dimensions did Melzack and Casey describe pain in terms of?
Answer: three


Question: Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.
Is there an answer to this question: Who does a non-conventional aircraft rely upon to moniter the aircraft's approach and transmit the data to the pilot?

Answer: unanswerable


Question: On May 20, 1971, his brother, Meinhard, died in a car accident. Meinhard had been drinking and was killed instantly. Schwarzenegger did not attend his funeral. Meinhard was due to marry Erika Knapp, and the couple had a three-year-old son, Patrick. Schwarzenegger would pay for Patrick's education and help him to emigrate to the United States. Gustav died the following year from a stroke. In Pumping Iron, Schwarzenegger claimed that he did not attend his father's funeral because he was training for a bodybuilding contest. Later, he and the film's producer said this story was taken from another bodybuilder for the purpose of showing the extremes that some would go to for their sport and to make Schwarzenegger's image more cold and machine-like in order to fan controversy for the film. Barbara Baker, his first serious girlfriend, has said he informed her of his father's death without emotion and that he never spoke of his brother. Over time, he has given at least three versions of why he was absent from his father's funeral.
Is there an answer to this question: What is Meinhard's son named?

Answer:
Patrick
