 Question: can you have a heart attack from laughing Context: The Paleolithic is often held to finish at the end of the ice age (the end of the Pleistocene epoch), and Earth's climate became warmer. This may have caused or contributed to the extinction of the Pleistocene megafauna, although it is also possible that the late Pleistocene extinctions were (at least in part) caused by other factors such as disease and overhunting by humans. New research suggests that the extinction of the woolly mammoth may have been caused by the combined effect of climatic change and human hunting. Scientists suggest that climate change during the end of the Pleistocene caused the mammoths' habitat to shrink in size, resulting in a drop in population. The small populations were then hunted out by Paleolithic humans. The global warming that occurred during the end of the Pleistocene and the beginning of the Holocene may have made it easier for humans to reach mammoth habitats that were previously frozen and inaccessible. Small populations of wooly mammoths survived on isolated Arctic islands, Saint Paul Island and Wrangel Island, until c. 3700 BCE and c. 1700 BCE respectively. The Wrangel Island population became extinct around the same time the island was settled by prehistoric humans. There is no evidence of prehistoric human presence on Saint Paul island (though early human settlements dating as far back as 6500 BCE were found on the nearby Aleutian Islands).
 Question: was the ice age during the paleolithic era Context: One of the conditions that Republic placed on Ford was that the film run under two hours. However, the finished picture was two hours and nine minutes. When screening the film for Republic executives, Ford stopped the film at approximately two hours in, on the verge of the climactic fistfight. Republic executives relented and allowed the film to run its full length. It was one of the few films that Republic filmed in Technicolor; most of the studio's other color films were made in a more economical process known as Trucolor.
 Question: was the quiet man filmed in black and white Context: Although the soft, orange sweet potato is often called a ``yam'' in parts of North America, the sweet potato is botanically very distinct from a genuine yam (Dioscorea), which is native to Africa and Asia and belongs to the monocot family Dioscoreaceae. To add to the confusion, a different crop plant, the oca (Oxalis tuberosa, a species of wood sorrel), is called a ``yam'' in many parts of Polynesia, including New Zealand.
 Question: are sweet potatos and yams the same thing Context: The crossing had always been tolled, and from 1 April 2003 this became a charge, though since 2008 it has been free from 10 pm to 6 am. An automatic number plate recognition charging scheme (Dart Charge) began in November 2014. As a result, the charge can no longer be paid in cash and the old toll booths have been removed. A residents' scheme is available, offering further discounts for people living near the crossing.
