Problem: Please answer correctly the following question related to the paragraph below. In which city is it easier for citizens to breathe? There are two neighboring cities, Brampton and Filtroy. The two towns depend on each other by trading supplies and goods regularly. Filtroy is located on top of a very tall mountain, and Brampton is situated at the base of this hill. For this reason, it can sometimes be difficult to traverse the roads to trade goods, but it's important to do it so both cities can thrive. Hint: Like water in the ocean, air in the atmosphere exerts pressure that increases with depth. Most gas molecules in the atmosphere are pulled close to Earth's surface by gravity. As a result, air pressure decreases quickly at lower altitudes and then more slowly at higher altitudes. This is illustrated in Figure below . Air pressure is greatest at sea level, where the depth of the atmosphere is greatest. At higher altitudes, the pressure is less because the depth of the atmosphere is less. For example, on top of Mount Everest, the tallest mountain on Earth, air pressure is only about one-third of the pressure at sea level. At such high altitudes, low air pressure makes it hard to breathe and is dangerous to human health.

A: Brampton

Problem: Please answer correctly the following question related to the paragraph below. Which group didn't consume excess dietary lipids? Two groups of people followed different diets. Group A was comprised of vegans, while group B had a regular diet, with the mention they ate a lots of fatty foods and fast-food. Hint: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis.

A: Group A

Problem: Please answer correctly the following question related to the paragraph below. Which island burned more fossil fuels? Two neighboring islands Grey island and Sand island both contributed to global warming by their actions. Grey island contributed way more because they were more careless. Hint: Another major cause of extinction is global warming , which is also known as global climate change. During the past century, the Earth's average temperature has risen by almost 1C (about 1.3F). You may not think that is significant, but to organisms that live in the wild and are constantly adapting to their environments, any climate change can be hazardous. Recall that burning fossil fuels releases gasses into the atmosphere that warm the Earth. Our increased use of fossil fuels, such as coal and oil, is changing the Earth's climate. Any long-term change in the climate can destroy the habitat of a species. Even a brief change in climate may be too stressful for an organism to survive. For example, if the seas increase in temperature, even briefly, it may be too warm for certain types of fish to reproduce.

A: Grey

Problem: Please answer correctly the following question related to the paragraph below. Which island had fewer birds that could eat only smaller seeds? Two islands inhabited by many species of finches went through some climatic changes during the past several years. While Park island hat wetter than average years, Boat island experienced years of drought, so many birds died. Hint: While the Grants were on the Galapagos, a drought occurred. As a result, fewer seeds were available for finches to eat. Birds with smaller beaks could crack open and eat only the smaller seeds. Birds with bigger beaks could crack and eat seeds of all sizes. As a result, many of the small-beaked birds died in the drought. Birds with bigger beaks survived and reproduced (see Figure below ). Within 2 years, the average beak size in the finch population increased. Evolution by natural selection had occurred.

A:
Park
