Problem: You are given a new situation: Guyana and Nigeria had thriving economies. Guyana's economy was based on conventional agriculture, while Nigeria attracted an enormous number of tourists to its splendid beaches each year. and a hint : Marine pollution is a generic term for the entry into the ocean of potentially hazardous chemicals or particles. The biggest culprits are rivers and with them many agriculture fertilizer chemicals as well as livestock and human waste. The excess of oxygen-depleting chemicals leads to hypoxia and the creation of a dead zone.Marine debris, which is also known as marine litter, describes human-created waste floating in a body of water. Oceanic debris tends to accumulate at the center of gyres and coastlines, frequently washing aground where it is known as beach litter. Please answer this question : Which country caused less hypoxia?

A: Nigeria

Problem: Given the question: You are given a new situation: John wanted to charge his electronic gadgets remotely. To that end, he first conducted two experiments, case A and case B. In case A he used conduction, and in case B he used induction. In both cases he used same two objects. Finally, John tried to charge his phone remotely. He called this test as case C. and a hint : Charging an object by touching it with another charged object is called charging by conduction. By bringing a charged object into contact with an uncharged object, some electrons will migrate to even out the charge on both objects. Charging by conduction gives the previously uncharged object a permanent charge. An uncharged object can also be charged using a method called charging by induction . This process allows a change in charge without actually touching the charged and uncharged objects to each other. Imagine a negatively charged rod held near the knob, but not touching. If we place a finger on the knob, some of the electrons will escape into our body, instead of down the stem and into the leaves. When both our finger and the negatively charged rod are removed, the previously uncharged electroscope now has a slight positive charge. It was charged by induction. Notice that charging by induction causes the newly charged object to have the opposite charge as the originally charged object, while charging by conduction gives them both the same charge. Please answer this question : Which experiment would be more appropriate for case C, case A or case B?
++++++++++++++++++++++++++++++++
The answer is:
case B

input question: You are given a new situation: Manny visited 2 countries. First he visited Australia, a country which respected the environment and produced zero air pollution, and New Zealand, a country which based its economy on burning fossil fuels and generated a lot of air pollution. and a hint : Air pollution is harmful to human beings and other living things. About 22 million people die from air pollution each year. Breathing polluted air increases the risk of developing lung diseases such as asthma and lung cancer. Breathing bad air also increases the chances of dying from other diseases. Children are most likely to be affected by air pollution. That's because their lungs are still developing and growing. Children also take in more air for their size than adults do. Some air pollutants damage the environment as well as the health of living things. The type of damage depends on the pollutant. Air pollution can also harm the environment. Please answer this question : Which country had fewer children affected by air pollution????
output answer: Australia

You are given a new situation: Archimedes was a great scientist. He was also a great inventor of machines. He once said that if he could stand somewhere, he could move the earth with his machine. Hearing that, king of Sicily called Archimedes and his fellow scientist Ptolemy to come up with great inventions. Archimedes, as everyone expected, came up with a great machine. But Ptolemy couldn't do much in such a limited time. So, his device was not a machine. and a hint : Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. Contrary to popular belief, machines do not increase the amount of work that is done. They just change how the work is done. So if a machine increases the force applied, it must apply the force over a shorter distance. Similarly, if a machine increases the distance over which the force is applied, it must apply less force. Please answer this question : Would Ptolemy's device have created less or more applied force than Archimedes' one?

Answer: less

Q: You are given a new situation: 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. and a hint : 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. Please answer this question : Which friend was more likely to be obese?
A: Paul

[Q]: You are given a new situation: A brother and sister are going to the doctor to get their physical done before the start of the school year. Jessica, the sister, and Mike, the brother, are both in the same grade in high school. Neither person is having any issues, but are simply going as a precautionary measure in case there is something the doctor can find out. Also, it's a requirement to get regular physicals in order to attend schools so that's another major reason both are going. and a hint : Boys and girls between the ages of 9 and 13 should get 9 mg of iron every day. Girls between the ages of 14 and 18 should get 15 mg of iron every day. Boys between the ages of 14 and 18 should get 11 mg of iron every day. Pregnant women need the most iron27 mg daily. Good sources of iron include shellfish, such as clams and oysters. Red meats, such as beef, are also a good source of iron. Non-animal sources of iron include seeds, nuts, and legumes. Breakfast cereals often have iron added to them in a process called fortification. Some good sources of iron are listed below ( Table below ). Eating vitamin C along with iron-containing food increases the amount of iron that the body can absorb. Please answer this question : Who needs less iron on a daily basis?
****
[A]:
Mike
