Problem: Given the question: Given the background: Alpine tundra occurs at high enough altitude at any latitude. Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, and the Eastern Rift mountains of Africa.Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well; the treeline often occurs at higher elevations on warmer equator-facing slopes. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography.Averaging over many locations and local microclimates, the treeline rises 75 metres (245 ft) when moving 1 degree south from 70 to 50N, and 130 metres (430 ft) per degree from 50 to 30N. Between 30N and 20S, the treeline is roughly constant, between 3,500 and 4,000 metres (11,500 and 13,100 ft). and the situation: Two countries from the same continent have very different climates. Icelandia, located at 70N latitude, and Uganda, situated just south of 30N, Icelandia was mostly flat, had a few mountains under 1,000 ft, but Uganda had a mountain range with peaks just under 3,000 ft. Answer the following question: Which country had fewer shrublands ecoregions?
++++++++++++++++++++++++++++++++
The answer is:
Uganda

Problem: Given the question: Given the background: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn't work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer's disease. and the situation: Sam is going to visit his grandfather. His grandfather lives in a retirement home and can barely take care of himself anymore. Answer the following question: Will Sam's grandfather have an increased or decreased chance of developing Alzheimer's disease?
++++++++++++++++++++++++++++++++
The answer is:
increased

Problem: Given the question: Given the background: One reason radiation is dangerous is that it can't be detected with the senses. You normally can't see it, smell it, hear it, or feel it. Fortunately, there are devices such as Geiger counters that can detect radiation. A Geiger counter, like the one in Figure below , has a tube that contains atoms of a gas. If radiation enters the tube, it turns gas atoms to ions that carry electric current. The current causes the Geiger counter to click. The faster the clicks occur, the higher the level of radiation. and the situation: David was visiting Japan. First, he went to Fukushima where the recent nuclear plant disaster happened. He found the city still had very high radiation. Then he visited Hiroshima. He found that Hiroshima had some low radiation. Finally, he visited the capital city Tokyo. He found that Tokyo did not have any radiation. Answer the following question: In Fukushima would a Geiger counter click faster or slower than Hiroshima?
++++++++++++++++++++++++++++++++
The answer is:
faster
