TASK DEFINITION: In this task, you are given a question and a context passage. You have to answer the question based on the given passage.
PROBLEM: How common are carbonates and deposits in North America?, Context: To the north of Africa the Tethys Sea continued to narrow. Broad shallow seas advanced across central North America (the Western Interior Seaway) and Europe, then receded late in the period, leaving thick marine deposits sandwiched between coal beds. At the peak of the Cretaceous transgression, one-third of Earth's present land area was submerged. The Cretaceous is justly famous for its chalk; indeed, more chalk formed in the Cretaceous than in any other period in the Phanerozoic. Mid-ocean ridge activity—or rather, the circulation of seawater through the enlarged ridges—enriched the oceans in calcium; this made the oceans more saturated, as well as increased the bioavailability of the element for calcareous nanoplankton. These widespread carbonates and other sedimentary deposits make the Cretaceous rock record especially fine. Famous formations from North America include the rich marine fossils of Kansas's Smoky Hill Chalk Member and the terrestrial fauna of the late Cretaceous Hell Creek Formation. Other important Cretaceous exposures occur in Europe and China. In the area that is now India, massive lava beds called the Deccan Traps were laid down in the very late Cretaceous and early Paleocene.

SOLUTION: widespread

PROBLEM: If you need to know how to do a certain skill where will you likely learn how?, Context: Canada's Armed forces operate out of 27 Canadian Forces bases (CFB) across the country, including NDHQ. This number has been gradually reduced since the 1970s with bases either being closed or merged. Both officers and non-commissioned members receive their basic training at the Canadian Forces Leadership and Recruit School in Saint-Jean-sur-Richelieu. Officers will generally either directly enter the Canadian Armed Forces with a degree from a civilian university, or receive their commission upon graduation from the Royal Military College of Canada. Specific element and trade training is conducted at a variety of institutions throughout Canada, and to a lesser extent, the world.

SOLUTION: at a variety of institutions throughout Canada

PROBLEM: What is an example of the widening gap between prosperous urban dwellers and struggling rural people?, Context: Experts point out that the earthquake hit an area that has been largely neglected and untouched by China's economic rise. Health care is poor in inland areas such as Sichuan, highlighting the widening gap between prosperous urban dwellers and struggling rural people. Vice Minister of Health Gao Qiang told reporters in Beijing that the "public health care system in China is insufficient." The Vice Minister of Health also suggested that the government would pick up the costs of care to earthquake victims, many of whom have little or no insurance: "The government should be responsible for providing medical treatment to them," he said.

SOLUTION:
Health care
