You are given a new situation: John has just started working at a new company. Although he has been in the workforce for many years, this is a new position for him, and he is excited for it. Two weeks after starting, John's branch of the company is hosting a retirement party for one of the longest tenured employees at the office, Brad. Although Brad has enjoyed his time at the company, he says he is excited to be able to take time to himself and relax each day instead of coming into the office. and a hint : Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. Please answer this question : Who would struggle to lift a heavy box more?

Answer: Brad

Q: You are given a new situation: David wants to revisit the theory of evolution proposed by Darwin and Wallace. He is particularly interested in two species of deer, species A and species B. Species A has some helpful traits, but species B has some harmful traits. He is planning to write a paper on why some species are greater in number while others are smaller in number. and a hint : The theory of evolution by natural selection was proposed at about the same time by both Charles Darwin and Alfred Russel Wallace, shown in Figure below , and was set out in detail in Darwin's 1859 book On the Origin of Species . Natural selection is a process that causes heritable traits that are helpful for survival and reproduction to become more common, and harmful traits, or traits that are not helpful or advantageous for survival to become more rare in a population of organisms. This occurs because organisms with advantageous traits are more "fit" to survive in a particular environment and have "adapted" to the conditions of that environment. These individuals will have greater reproductive success than organisms less fit for survival in the environment. This will lead to an increase in the number of organisms with the advantageous trait(s) over time. Over many generations, adaptations occur through a combination of successive, small, random changes in traits, and natural selection of those variants best-suited for their environment. Natural selection is one of the cornerstones of modern biology. Please answer this question : Which species' traits would be less common, species A or species B?
A: species B

Question: You are given a new situation: Martin is moving and he needs to make a ramp so he can load heavy furniture into his truck. He has a bad back, so he wants to use the least effort possible. Before he cuts the wood, he is trying to decide how long the ramp should be so he can move the heavy furniture easily. and a hint : For an inclined plane, the input distance is the length of the sloping surface, and the output distance is the maximum height of the inclined plane. This was illustrated in Figure above . Because the sloping surface is always greater than the height of the inclined plane, the ideal mechanical advantage of an inclined plane is always greater than 1. An inclined plane with a longer sloping surface relative to its height has a gentler slope. An inclined plane with a gentler slope has a greater mechanical advantage and requires less input force to move an object to a higher elevation. Please answer this question : Should martin build a long or short ramp?
Answer: long

[Q]: You are given a new situation: John is an automotive enthusiast. He was visiting the auto show in his city. Two cars caught his attention, car A and car B. Car A was newer and it had catalytic converter. On the contrary, car B was older and didn't have catalytic converter. But he found the design of older car more attractive. and a hint : Catalytic converters in cars increase the rates of several important reactions. Unburned hydrocarbons can more easily be converted to carbon dioxide and water in the presence of a catalyst. Additionally, carbon monoxide (a harmful gas produced by incomplete combustion of fuel) is further oxidized to carbon dioxide, and nitrous oxide compounds (which contribute to smog and acid rain) are transformed back into nitrogen and oxygen gases. By passing car exhaust over these catalysts before their release into the air, the emissions from a combustion engine are made into much less harmful substances, resulting in a much cleaner atmosphere. Please answer this question : Would car A emit less or more carbon monoxide than car B?
****
[A]: less

input: Please answer the following: You are given a new situation: Ben and Jerry were two friends with very different dietary habits. Jerry ate healthy food, and was always on top of his caloric consumption, while Ben overate because he loved fatty foods such as butter, bacon et al. and a 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. Please answer this question : Which friend had a higher blood lipid level?
++++++++++
output: Ben

You are given a new situation: Jason and Barbara went out swimming at the beach while on vacation. Before heading outside, Barbara put sunscreen on her body and then handed the bottle to Jason. Jason decided that it wasn't sunny enough out to warrant sunscreen and didn't put any on. and a hint : Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. Please answer this question : Who is less likely to get skin cancer?

Answer:
Barbara
