[Q]: I read this background article the other day: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. I am facing a new situation today: Two siblings Jane and Matt, needed eyeglasses. Matt was nearsighted, while Jane was farsighted. they bought themselves two nice pairs of eyeglasses. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sibling didn't have a difficulty seeing distant objects?
****
[A]: Jane
input: Please answer the following: I read this background article the other day: Infrared (IR) light is electromagnetic radiation with a wavelength between 0.7 and 300 micrometers, which corresponds to a frequency range between 430 and 1 THz respectively. IR wavelengths are longer than that of visible light, but shorter than that of microwaves. Infrared may be detected at a distance from the radiating objects by "feel." Infrared sensing snakes can detect and focus infrared by use of a pinhole lens in their heads, called "pits". Bright sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 53% is infrared radiation, 44% is visible light, and 3% is ultraviolet radiation. I am facing a new situation today: Different wavelength electromagnetic radiations have different uses. John is a physicist. He needed to find appropriate wavelength electromagnetic radiations for his experiments. To that end, he selected three electromagnetic radiations, microwaves, infrared light, and visible light. He noted microwaves as case A, infrared as case B, and visible light as case C. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would case A have longer or shorter wavelengths than case B?
++++++++++
output: longer
Please answer this: I read this background article the other day: Hypertension , which is also called "high blood pressure," occurs when a person's blood pressure is always high. Hypertension is said to be present when a person's systolic blood pressure is always 140 or higher, and/or if the person's diastolic blood pressure is always 90 or higher. Having hypertension increases a person's chance for developing heart disease, having a stroke, or suffering from other serious cardiovascular diseases. Hypertension often does not have any symptoms, so a person may not know that he or she has high blood pressure. For this reason, hypertension is often called the "silent killer." Treatments for hypertension include diet changes, exercise, and medication. Foods thought to lower blood pressure include skim milk, spinach, beans, bananas and dark chocolate. I am facing a new situation today: Tom and Jerry were two 50-year-olds which went to high-school together. They recently met and discussed their health problems over coffee. Tom had hypertension and the doc told him to change his diet. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend had to start exercising?
++++++++
Answer: Tom
Problem: I read this background article the other day: 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. I am facing a new situation today: Ann decided to candy half of the fruit he received as a gift. She kept the other half to eat fresh and do juicing. She candied ginger, plums pears, and she didn't candy apples, oranges apricots and bananas. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruit contains more crystallized sugar, ginger or apples?

A: ginger
Problem: Given the question: I read this background article the other day: Using longitudinal data from over 100 countries, Diener and his colleagues showed that rich countries are in general happier than poor countries (Diener, Tay, & Oishi, 2013).[17] Also, life satisfaction for most countries goes up as they become wealthier over time. Diener identified three factors that influence the relationship between income and SWB. Namely, rising income most likely results in higher SWB when it leads to greater optimism, financial satisfaction and household material prosperity among citizens. Furthermore, Diener and his colleagues investigated the relationship between income and different elements of SWB. They illustrated that income has stronger influence on people's evaluation of their lives than the positive or negative emotions they experience over time (Diener, Kahneman, Tov, & Arora, 2010).[18] The study points to the necessity to evaluate different elements of SWB separately instead of treating happiness as a single entity. I am facing a new situation today: Two neighboring countries implemented different sets of economic reforms. The reforms took over a decade to implement, but the effects were not similar at all. Redvania was more prosperous and it became much richer, while Blueland stagflated and the inhabitants were not pleased with the outcome. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country experienced more stagflation after 10 years?
++++++++++++++++++++++++++++++++
The answer is:
Blueland
Problem: I read this background article the other day: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. I am facing a new situation today: Beijing recently significantly increased the amount of cars on the roads there through mandatory price cuts for all motor vehicles. In Montreal, the number of cars on the roads has decreased drastically recently through public transportation initiatives and public advertising campaigns encouraging biking and walking. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which area will produce fewer nitrogen oxides?

A:
Montreal
