[Q]: I have a new situation: Rob is competing in a cross country race. After running about a mile he reached a place with two signs, sign A and sign B. Sign A says that it's a quicksand. But sign B says that it's not a quicksand. He has to decide which way to go. But I can use this background: Quicksand forms in saturated loose sand when the sand is suddenly agitated. When water in the sand cannot escape, it creates a liquefied soil that loses strength and cannot support weight. Quicksand can form in standing water or in upwards flowing water (as from an artesian spring). In the case of upwards flowing water, forces oppose the force of gravity and suspend the soil particles. The saturated sediment may appear quite solid until a sudden change in pressure or shock initiates liquefaction. This causes the sand to form a suspension and lose strength. The cushioning of water gives quicksand, and other liquefied sediments, a spongy, fluid-like texture. Objects in liquefied sand sink to the level at which the weight of the object is equal to the weight of the displaced soil/water mix and the submerged object floats due to its buoyancy. What is an answer for this question: Would sing B indicate spongy texture or not spongy texture of the soil?
****
[A]: not spongy texture

[Q]: I have a new situation: Ron, a sociologist, traveled to two very different societies, society A and society B, for several months each and wrote down his observations. Ron is now examining the data he gathered from the two societies in an attempt to draw scientific conclusions, and write up a paper. In society A, he found that there were high levels of income inequality, while society B had low levels of income inequality. But I can use this background: Research has shown an inverse link between income inequality and social cohesion. In more equal societies, people are much more likely to trust each other, measures of social capital (the benefits of goodwill, fellowship, mutual sympathy and social connectedness among groups who make up a social units) suggest greater community involvement, and homicide rates are consistently lower. What is an answer for this question: Will people in society B be more likely or less likely to trust people compared to society A?
****
[A]: more likely

[Q]: I have a new situation: Xuejiang, a town in China, recently increased their levels of steel and construction materials production. The factories that produce these materials have been burning high levels of fossil fuels to support this production. Ontario, meanwhile, has been burning low levels of fossil fuels thanks to investment in alternative energies, and a general decrease in the manufacturing industries there. But I can use this background: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change. What is an answer for this question: Which area will release less carbon dioxide, Xuejiang or Ontario?
****
[A]: Ontario

[Q]: I have a new situation: Two lakes similar in size are situated 5 miles from one another in the mountains. Both Red and White lake fill with snow water every spring. Red lake is almost emptied in the fall; White lake during the summer. But I can use this background: The water level is seasonal, being lowered by about 10 feet (3.0 m) over the winter. The reservoir fills in the spring from snow melt and underground springs. The lake is usually at full level by late spring, but in the occasional years of low snow melt and low rainfall, it may remain up to several feet below its typical level. Water is let out of the lake in the fall so that ice will not damage docks and other structures around the lake. This also leads to excellent water quality, as a significant portion of the water is replaced every year. What is an answer for this question: Which lake had a higher water level during the summer?
****
[A]:
Red
