input: Please answer the following: I read this background article the other day: Raising the temperature of a chemical reaction usually results in a higher rate of reaction. When the reactant particles are heated, they move faster and faster. This results in a greater frequency of collisions. A more important effect of the temperature increase is that the collisions occur with a greater force and are thus more likely to surmount the activation energy barrier and go on to form products. Increasing the temperature of a reaction increases the number of effective collisions between reacting particles, so the reaction rate increases. I am facing a new situation today: Two colleagues read about types of chemical reactions. Sean studied about the influence of temperature on chemical reactions. Gabe studied about other influencing factors. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student read less about a greater frequency of collisions?

output: Gabe

input: Please answer the following: 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 B needed John to move it more or less quickly than fork A?

input: Please answer the following: I read this background article the other day: Any unused energy in foodwhether it comes from carbohydrates, proteins, or lipidsis 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: Greg wants to go on a diet. He decided it's time to make a change. He cut down on how much he eats every day and monitors his calorie intake, making sure that he is burning more calories that he is taking in. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Given Greg's weight and height are 136 kg and 1.8 meters, is his BMI ~75.5 or ~42

output: 42

input: Please answer the following: I read this background article the other day: As time passes, the number of HIV copies keeps increasing, while the number of helper T cells keeps decreasing. The graph in Figure below shows how the number of T cells typically declines over a period of many years following the initial HIV infection. As the number of T cells decreases, so does the ability of the immune system to defend the body. As a result, an HIV-infected person develops frequent infections. Medicines can slow down the virus but not get rid of it, so there is no cure at present for HIV infections or AIDS. There also is no vaccine to immunize people against HIV infection, but scientists are working to develop one. I am facing a new situation today: Jacob recently contracted the HIV virus and is going to his first support meeting. While there, he meets Dan and strikes up a conversation with him. Dan says that he has had HIV for over a decade at this point and has learned ways to live with it. He is able to give Jacob some good advice on how to handle things and Jacob is very grateful to have someone to talk with. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who has less T cells, Jacob or Dan?
++++++++++
output:
Dan
