Problem: Please answer a question about the following article about Houston:
One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.
When did Houston begin to regain its dependence on the oil industry?
A: 2000s
Problem: Please answer a question about the following article about Buddhism:
Rebirth refers to a process whereby beings go through a succession of lifetimes as one of many possible forms of sentient life, each running from conception to death. The doctrine of anatta (Sanskrit anatman) rejects the concepts of a permanent self or an unchanging, eternal soul, as it is called in Hinduism and Christianity. According to Buddhism there ultimately is no such thing as a self independent from the rest of the universe. Buddhists also refer to themselves as the believers of the anatta doctrineNairatmyavadin or Anattavadin. Rebirth in subsequent existences must be understood as the continuation of a dynamic, ever-changing process of pratityasamutpada ("dependent arising") determined by the laws of cause and effect (karma) rather than that of one being, reincarnating from one existence to the next.
In Buddhism, rebirth into consecutive lives is determined by what?
A: the laws of cause and effect
Problem: Please answer a question about the following article about 51st state:
Several days after the referendum, the Resident Commissioner Pedro Pierluisi, Governor Luis Fortuno, and Governor-elect Alejandro Garcia Padilla wrote separate letters to the President of the United States Barack Obama addressing the results of the voting. Pierluisi urged Obama to begin legislation in favor of the statehood of Puerto Rico, in light of its win in the referendum. Fortuno urged him to move the process forward. Garcia Padilla asked him to reject the results because of their ambiguity. The White House stance related to the November 2012 plebiscite was that the results were clear, the people of Puerto Rico want the issue of status resolved, and a majority chose statehood in the second question. Former White House director of Hispanic media stated, "Now it is time for Congress to act and the administration will work with them on that effort, so that the people of Puerto Rico can determine their own future."
How did these politicians voice their concerns?
A: wrote separate letters to the President of the United States Barack Obama
Problem: Please answer a question about the following article about CBC Television:
Most CBC television stations, including those in the major cities, are owned and operated by the CBC itself. CBC O&O stations operate as a mostly seamless national service with few deviations from the main network schedule, although there are some regional differences from time to time. For on-air identification, most CBC stations use the CBC brand rather than their call letters, not identifying themselves specifically until sign-on or sign-off (though some, like Toronto's CBLT, do not ID themselves at all except through PSIP). All CBC O&O stations have a standard call letter naming convention, in that the first two letters are "CB" (an ITU prefix allocated not to Canada, but to Chile) and the last letter is "T". Only the third letter varies from market to market; however, that letter is typically the same as the third letter of the CBC Radio One and CBC Radio 2 stations in the same market. An exception to this rule are the CBC North stations in Yellowknife, Whitehorse and Iqaluit, whose call signs begin with "CF" due to their historic association with the CBC's Frontier Coverage Package prior to the advent of microwave and satellite broadcasting.
Who owns and operates most of the CBC television stations?
A:
CBC itself
