Q: 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: Who would see distant objects more clearly, John or Keith?
A: Keith

Q: I have a new situation: 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. But I can use this background: 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. What is an answer for this question: If a student's body is fighting infection will their body temperature be normal or high?
A: high

Q: I have a new situation: Two friends met after 20 years. Tom had been smoking tobacco all these years and had some health problems related to that, while Randy quit smoking 25 years ago. But I can use this background: Many different chemical substances cause cancer. Dozens of chemicals in tobacco smoke, including nicotine, have been shown to cause cancer ( Figure below ). In fact, tobacco smoke is one of the main sources of chemical carcinogens. Smoking tobacco increases the risk of cancer of the lung, mouth, throat, and bladder. Using smokeless tobacco can also cause cancer. Other chemicals that cause cancer include asbestos, formaldehyde, benzene, cadmium, and nickel. What is an answer for this question: Which friend had a lower risk of developing cancer of the lung?
A: Randy

Q: I have a new situation: Two neighboring police Departments took different approaches to fighting crime, Greenville P.D. did not invest in DNA testing, improved forensics, and information technology, while Grayville took extensive measures of that nature. But I can use this background: Law enforcement officers are often unfamiliar with information technology, and so lack the skills and interest in pursuing attackers. There are also budgetary constraints. It has been argued that the high cost of technology, such as DNA testing, and improved forensics mean less money for other kinds of law enforcement, so the overall rate of criminals not getting dealt with goes up as the cost of the technology increases. In addition, the identification of attackers across a network may require logs from various points in the network and in many countries, the release of these records to law enforcement (with the exception of being voluntarily surrendered by a network administrator or a system administrator) requires a search warrant and, depending on the circumstances, the legal proceedings required can be drawn out to the point where the records are either regularly destroyed, or the information is no longer relevant. What is an answer for this question: Which P.D. had more success in fighting crime?
A:
Grayville
