Question: Given the background: 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. and the situation: Two friends found out more about cancer. Bill got scared and started making healthy lifestyle choices, while Dan carried on with his life as if nothing happened. Answer the following question: Which friend didn't start avoiding carcinogens?
Answer: Dan

[Q]: Given the background: Parallel slowdown is a phenomenon in parallel computing where parallelization of a parallel algorithm beyond a certain point causes the program to run slower (take more time to run to completion).[1] Parallel slowdown is typically the result of a communications bottleneck. As more processor nodes are added, each processing node spends progressively more time doing communication than useful processing. At some point, the communications overhead created by adding another processing node surpasses the increased processing power that node provides, and parallel slowdown occurs. and the situation: John landed a job as an IT manager. His boss asked him to figure out problems in two similar programs, program A and program B. John found program A having parallel slowdown, but program B does not have parallel slowdown. He has to weigh the merits of using these programs. Answer the following question: Which program is doing more useful processing, program A or program B?
****
[A]: program B

input: Please answer the following: Given the background: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] and the situation: Mary and Ann got some fruit as a gift from a friend. Mary decided to candy the fruit, while Ann decided to eat them fresh, Mary received plums, peaches, apples and oranges. Ann got pears, quince, cherries and blackberries. Answer the following question: Which fruit retained their quality longer plums or quince?
++++++++++
output: plums

Please answer this: Given the background: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species. and the situation: Two students studied animal behavior for the biology class. Ned studied more about predators, while Kim studied more about herbivores. Answer the following question: Which student learned less about rabbits?
++++++++
Answer: Ned

Problem: Given the background: The lungs of mammals are unique in having alveoli . These are tiny, sac-like structures. Each alveolus is surrounded by a network of very small blood vessels (see Figure below ). Because there are millions of alveoli in each lung, they greatly increase the surface area for gas exchange between the lungs and bloodstream. Human lungs, for example, contain about 300 million alveoli. They give the lungs a total surface area for gas exchange of up to 90 square meters (968 square feet). That's about as much surface area as one side of a volleyball court! and the situation: Two six graders learned about the lives of animals. Lori learned more about fish, while Dan learned more about mammals. Answer the following question: Which student learned less about a network of very small blood vessels?

A: Lori

input: Please answer the following: Given the background: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. and the situation: Adam was playing tag football when one of his friends tagged him a bit too hard and caused him to tumble and fall. He noticed when he fell, he got a pretty bad cut in his knee. He decided to ignore the injury for now and keep playing. Later when he got home he realized the area of the cut was warm and swollen Answer the following question: Will the blood vessels near Adam's injury have expanded or contracted?
++++++++++
output:
expanded
