[Q]: You are given a new situation: John is comparing his medical record with his father's and son's medical records. John is 40 years old; his father is 70 years old; and his son is 10 years old. It appears that both John and his father has Retinitis. But his son does not have Retinitis. and a hint : Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the part of your eye that is also known as the "sensing tissue." Retinitis may be caused by a number of different infectious agents. Retinitis, also called Retinitis pigmentosa, has a prevalence of one in every 2,500-7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 2060 years old. Please answer this question : Whould Retinitis be a leading cause or minor cause of blindness for John's father?
****
[A]: minor cause

input: Please answer the following: You are given a new situation: Jacob and Thomas were conducting an experiment in a chemistry class. The goal of the experiment was to identify the strength of unknown acids by examining the products formed in a chemical reaction. After they completed the experiment, Jacob concluded that he was given a strong acid, while Thomas concluded that he was given a weak acid. and a hint : The stronger of two acids will have a higher Ka than the weaker acid; the ratio of hydrogen ions to acid will be higher for the stronger acid as the stronger acid has a greater tendency to lose its proton. Because the range of possible values for Ka spans many orders of magnitude, a more manageable constant, pKa is more frequently used, where pKa = log10 Ka. Stronger acids have a smaller pKa than weaker acids. Experimentally determined pKa at 25 C in aqueous solution are often quoted in textbooks and reference material. Please answer this question : Which person's acid, Jacob's or Thomas's, will have a lower ratio of hydrogen ions to acid?
++++++++++
output: Thomas's

Please answer this: You are given a new situation: Two farms had winds destroying their crops. Hill farm started installing windbreaks, while Valley farm didn't have the funds to do that so they postponed the project. and a hint : Windbreaks reduce wind velocity over and around crops. This increases yields through reduced drying of the crop and/or by preventing the crop from toppling in strong wind gusts. Please answer this question : Which farm reduced the wind velocity around crops?
++++++++
Answer: Hill

Problem: You are given a new situation: Two neighboring towns had different methods of growing crops. Lean town used insecticides, while Bean town did not. Lean town had high levels of air pollution. and a hint : Air pollution can also indirectly cause other health issues and even deaths. Air pollutants can cause an increase in cancer including lung cancer, eye problems, and other conditions. For example, using certain chemicals on farms, such as the insecticide DDT (dichlorodiphenyltrichloroethane) and toxic PCBs (polychlorinated biphenyl), can cause cancer. Indoors, pollutants such as radon or asbestos can also increase your cancer risk. Lastly, air pollution can lead to heart disease, including heart attack and stroke. Please answer this question : Which town had fewer inhabitants experiencing eye problems?

A: Bean

Problem: Given the question: You are given a new situation: A chemist is working in the lab with two beakers, beaker R and beaker T, filled with identical solutions. In her experiment, she is going to pour one liquid into beaker R and the same amount of a different liquid into beaker T. After pouring the liquid into beaker R, there is no noticeable change. Pouring the liquid into beaker T, she observes a change in the liquid. and a hint : A catalyst works by providing a lower energy pathway from reactants to products. The use of a catalyst involves intermediate reactions which have lower activation complexes than the original reaction. On a simplified reaction energy diagram, this can be thought of as lowering the activation energy for a given transformation. If the activation energy of a reaction is decreased, more collisions will have enough energy to overcome this lower barrier, so the reactant-to-product transformation will occur more frequently. As a result, the overall reaction rate will be higher than for an identical reaction with a larger activation energy barrier. Please answer this question : The reaction in which beaker has a higher activation energy?
++++++++++++++++++++++++++++++++
The answer is:
beaker R

Problem: You are given a new situation: Peter decided to sugar mangoes, ginger, pineapples, peaches to preserve them for next spring. He also bought blueberries and raspberries to eat fresh. and a hint : Sugaring is a food preservation method similar to pickling. Sugaring is the process of desiccating a food by first dehydrating it, then packing it with pure sugar. This sugar can be crystalline in the form of table or raw sugar, or it can be a high sugar density liquid such as honey, syrup or molasses. The purpose of sugaring is to create an environment hostile to microbial life and prevent food spoilage. Sugaring is commonly used to preserve fruits as well as vegetables such as ginger. From time to time sugaring has also been used for non-food preservations. For example, honey was used as part of the mummification process in some ancient Egyptian rites. A risk in sugaring is that sugar itself attracts moisture. Once a sufficient moisture level is reached, native yeast in the environment will come out of dormancy and begin to ferment the sugars into alcohol and carbon dioxide. This leads to the process of fermentation. Although fermentation can be used as a food preservation method, it must be intentionally controlled, or the results will tend to be unpleasant. Please answer this question : Which fruit had a higher sugar content, mangoes or blueberries?

A:
mangoes
