In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

[EX Q]: 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 activityor rather, the circulation of seawater through the enlarged ridgesenriched 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.
[EX A]: widespread

[EX Q]: Shabelle Media Network was NOT based in what city?, Context: Other radio stations based in Mogadishu include Mustaqbal Media corporation and the Shabelle Media Network, the latter of which was in 2010 awarded the Media of the Year prize by the Paris-based journalism organisation, Reporters Without Borders (RSF). In total, about one short-wave and ten private FM radio stations broadcast from the capital, with several radio stations broadcasting from the central and southern regions.
[EX A]: Paris

[EX Q]: Where is the Centennial Light?, Context: The relationships above are valid for only a few percent change of voltage around rated conditions, but they do indicate that a lamp operated at much lower than rated voltage could last for hundreds of times longer than at rated conditions, albeit with greatly reduced light output. The "Centennial Light" is a light bulb that is accepted by the Guinness Book of World Records as having been burning almost continuously at a fire station in Livermore, California, since 1901. However, the bulb emits the equivalent light of a four watt bulb. A similar story can be told of a 40-watt bulb in Texas that has been illuminated since 21 September 1908. It once resided in an opera house where notable celebrities stopped to take in its glow, and was moved to an area museum in 1977.
[EX A]:
a fire station
