Q: I read this background article the other day: Another obvious change that occurs during puberty is rapid growth. This is called the adolescent growth spurt . In boys, it is controlled by testosterone. The rate of growth usually starts to increase relatively early in puberty. At its peak rate, growth in height is about 10 centimeters (almost 4 inches) per year in the average male. Growth generally remains rapid for several years. Growth and development of muscles occur toward the end of the growth spurt in height. Muscles may continue to develop and gain strength after growth in height is finished. I am facing a new situation today: Joseph and Walter are two brothers who have always gotten along well, but are now going to be separated for the first time in their lives. Walter has just graduated high school and is going off to live at college several states away from home. Joseph is about to be a freshman in high school, so he has several years before he will even have the possibility of going off to the same college as his brother. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which boy is currently more likely to be shorter?
A: Joseph
Question: I read this background article the other day: A thermometer is a device used to measure temperature. It is placed in contact with an object and allowed to reach thermal equilibrium with the object (they will have the same temperature). The operation of a thermometer is based on some property, such as volume, that varies with temperature. The most common thermometers contain liquid mercury, or some other liquid, inside a sealed glass tube. The liquid expands and contracts faster than the glass tube. Therefore, when the temperature of the thermometer increases, the liquid volume expands faster than the glass volume, allowing the liquid to rise in the tube. The positions of the liquid in the tube can then be calibrated for accurate temperature readings. Other properties that change with temperature can also be used to make thermometers; liquid crystal colors and electrical conductivity change with temperature, and are also relatively common thermometers. I am facing a new situation today: A group of middle school students is measuring the temperature of various liquids for a chemistry lab using a mercury thermometer. They have a beaker of boiling water, a beaker of ice water, and a beaker of water at room temperature. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: If the students move the thermometer from the ice water to the room temperature water will the mercury level rise or fall?
Answer: rise
[Q]: I read this background article the other day: When you go to the dentist to get a tooth pulled, you really don't want to feel any pain. The dentist injects an anesthetic into your gum and it eventually becomes numb. One theory as to why anesthetics work deals with the movement of ions across the cell membrane. The anesthetic gets into the membrane structure and causes shifts in how ions move across the membrane. If ion movement is disrupted, nerve impulses will not be transmitted and you will not sense pain at least not until the anesthetic wears off. I am facing a new situation today: Jake and his brother Jordan both have to go to the dentist to get a tooth pulled. Jake is allergic to the anesthetic unfortunately, so he has to have the procedure done without it. Jordan isn't allergic, so he is able to get his tooth pulled after an anesthetic is injected. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who will experience less pain during the tooth extraction?
****
[A]: Jordan
input: Please answer the following: 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 less carbon monoxide into the atmosphere?
++++++++++
output: Red
Please answer this: I read this background article the other day: Magnetism is the ability of a material to be attracted by a magnet and to act as a magnet. Magnetism is due to the movement of electrons within atoms of matter. When electrons spin around the nucleus of an atom, it causes the atom to become a tiny magnet, with north and south poles and a magnetic field. In most materials, the north and south poles of atoms point in all different directions, so overall the material is not magnetic. Examples of nonmagnetic materials include wood, glass, plastic, paper, copper, and aluminum. These materials are not attracted to magnets and cannot become magnets. I am facing a new situation today: Rob got a compass as a present for his birthday. The magnet in the compass made him very interested in how magnets work. To understand magnets better he categorized objects in two groups, group A and group B. In group A all objects were magnetic, but in group B none of the objects was magnetic. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which group would not attract a magnet, group A or group B?
++++++++
Answer: group B
Question: I read this background article the other day: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span. I am facing a new situation today: The police arrested two homeless people. James was 35 and had been HIV positive for 20 years, and Bill, who was 54 and was not HIV positive. They booked them and let them go. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person had a disease that causes death?
Answer:
James
