Problem: Given the question: Please answer correctly the following question related to the paragraph below. Who is more likely to have a lower reflex time? Robert and his son Michael are going to the doctor for their yearly physical. Robert is currently in the late adulthood phase of his life. Michael, on the other hand, just began adulthood and is still quite young. Both of them want to ask the doctor about their risks for future health problems. Hint: 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.

The answer is:
Michael

Problem: Given the question: Please answer correctly the following question related to the paragraph below. If a patient with the virus does not have a fever is their body's immune system making more or less white blood cells than a patient with a fever? Stephanie is a nurse at the local high school. Recently, the flu has been going around and she has had many students come into her office feeling ill. When a student comes in, the first thing she does is check their temperature to test for a fever. A research facility is testing the immune response of patients with immune deficiency who are infected with a virus. Some of the patients are given a trial of a new medication that is supposed to increase their immune system's response to illness while others are in the control group. Hint: White blood cells also make chemicals that cause a fever. A fever is a higher-than-normal body temperature. Normal human body temperature is 98.6F (37C). Most bacteria and viruses that infect people reproduce fastest at this temperature. When the temperature is higher, the pathogens cannot reproduce as fast, so the body raises the temperature to kill them. A fever also causes the immune system to make more white blood cells. In these ways, a fever helps the body fight infection.

The answer is:
less

Problem: Given the question: Please answer correctly the following question related to the paragraph below. In which sample more rocks would have chemical reactions, sample A or sample B? Rob is an environmental scientist. He is looking at two samples of soil, sample A and sample B. Sample A is from Amazon Rain-forest, where they get one of the highest rainfall in the world. Sample B is from the Atacama Desert, where they get one of the lowest rainfall in the world. He needs to determine the properties of these samples. Hint: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering.

The answer is:
sample A
