I have a new situation: John and Keith are two friends. They went to see an ophthalmologist for an eye cheek up. The doctor found that John had myopia, but Keith had normal eyes. He advised them according to his findings. But I can use this background: Nearsightedness, or myopia, is the condition in which nearby objects are seen clearly, but distant objects appear blurry. The Figure below shows how it occurs. The eyeball is longer (from front to back) than normal. This causes images to be focused in front of the retina instead of on the retina. Myopia can be corrected with concave lenses. The lenses focus images farther back in the eye, so they fall on the retina instead of in front of it. What is an answer for this question: Whose eyeball would be longer than normal, John or Keith?
Ans: John

I have a new situation: Bob works for a data storage company. He has now three projects, project A, project B, and project C, simultaneously going on. All of them involves storing XML data. Project A has small volume of data, but project B and project C has large volume of data. He applied Fast Infoset format for project B, but didn't apply that format for project C. But I can use this background: Storing large volumes of data When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. What is an answer for this question: Will project C incur higher or lower storage cost than porject A?
Ans: higher

I have a new situation: Greg's grandma is a culinary expert. She is also very eager to teach others how to make great foods. One day she taught Greg how to make candied fruit. Greg was so excited about it that he bought two baskets of fruits, basket A and basket B, to make some candied fruits. He used the basket A fruits to make some candied fruits, but was too lazy to use the basket B fruits. He just kept the basket B fruits on his kitchen top. But I can use this 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] What is an answer for this question: Which fruits will not be saturated with sugar, basket A fruits or basket B fruits?
Ans: basket B fruits

I have a new situation: John is a doctor with the local hospital. Earlier today, he was seeing two patients, patient A and patient B. John found out that patient A had more LDL, but patient B had more HDL. He now needs to determine correct treatment for them. But I can use this background: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol. What is an answer for this question: Which patient would see more build up in the inner walls of the arteries, patient A or patient B?
Ans: patient A
