Please answer this: I read this background article the other day: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products. I am facing a new situation today: Blue island and Red island were two big sister islands situated 100 miles from each other. People on Blue island used gas powered vehicles, while people on Red island used electrical vehicles. The people on Blue island presented more respiratory problems. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which island released more carbon monoxide into the atmosphere?

Answer: Blue
Problem: I read this background article the other day: Any unused energy in food, whether it comes from carbohydrates, proteins, or lipids, is stored in the body as fat. An extra 3,500 Calories of energy results in the storage of almost half a kilogram (1 pound) of stored body fat. People who consistently consume more food energy then they need may become obese. Obesity occurs when the body mass index is 30.0 kg/m 2 or greater. Body mass index (BMI) is an estimate of the fat content of the body. It is calculated by dividing a person's weight (in kilograms) by the square of the person's height (in meters). Obesity increases the risk of health problems such as type 2 diabetes and hypertension. I am facing a new situation today: Two friends met after 20 years and compared diets. Paul ate junk food daily and weighed 300 lbs and was 5'8'' in height. Mike was vegan and stayed healthy and thin. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which friend was less likely to have a body mass index 30.0 kg/m 2 or greater?

A: Mike
Problem: Given the question: I read this background article the other day: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school. I am facing a new situation today: David is a doctor who works for the public health department. After analyzing health data for his city, he found twenty percent of the population have myopia. He categorized them as group A. Another eighty percent didn't have myopia. He put them in group B. He now needs to devise a plan on how to tackle myopia in his city. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group would less likely engage in visually intensive works, group A or group B?
++++++++++++++++++++++++++++++++
The answer is:
group B
input question: I read this background article the other day: The frequency of a wave is the same as the frequency of the vibrations that caused the wave. For example, to generate a higher-frequency wave in a rope, you must move the rope up and down more quickly. This takes more energy, so a higher-frequency wave has more energy than a lower-frequency wave with the same amplitude. You can see examples of different frequencies in the Figure below (Amplitude is the distance that particles of the medium move when the energy of a wave passes through them.) I am facing a new situation today: John was tuning his musical instruments with two tuning forks, fork A and fork B. He produced higher frequency with fork A and lower frequency with fork B. Interestingly, both frequencies had the same amplitude. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would fork A needed John to move it more or less quickly than fork B????
output answer: more
I read this background article the other day: A comet tailand comaare features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye. I am facing a new situation today: Year 2022 would be an interesting year when three comets would get scientists' attention - Comet A, Comet B, and Comet C. Comet A and C are very faint, but Comet B is very bright. Comet A would enter the inner solar system on February 10, 2022 and leave the inner solar system on February 20, 2022. Comet B would enter the inner solar system on February 18, 2022 and leave the inner solar system on February 26, 2022. Comet C would never enter the inner solar system. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Wich comet would not be visible to naked eyes on February 19, 2022, Comet A or Comet B?

Answer: Comet A
Q: I read this background article the other day: Carbon monoxide is used in modified atmosphere packaging systems in the US, mainly with fresh meat products such as beef, pork, and fish to keep them looking fresh. The carbon monoxide combines with myoglobin to form carboxymyoglobin, a bright-cherry-red pigment. Carboxymyoglobin is more stable than the oxygenated form of myoglobin, oxymyoglobin, which can become oxidized to the brown pigment metmyoglobin. This stable red color can persist much longer than in normally packaged meat. Typical levels of carbon monoxide used in the facilities that use this process are between 0.4% to 0.5%. I am facing a new situation today: Mike went to his local grocery store. He noticed that meats had two different packaging, product A and product B. When he looked closely, he found that in product A packaging carbon monoxide was used, but in product B carbon monoxide was not used. He asked the store clerk what difference it made. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which product's color would more likely turn brown, product A or product B?
A:
product B
