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: Which person's body will struggle more to defend from the HIV infection?
++++++++++
output: Dan

input: Please answer the following: I read this background article the other day: From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are the following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period, and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice. I am facing a new situation today: Albert is a scientist who travels the planet looking for new species to discover and analyze. While on a safari in Australia, Albert discovered two new species of live-bearing tetrapods. In the first species, species A, the adult individuals had high body mass on average. In the second species, species B, the adult individuals had low body mass on average. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which species will have smaller broods?
++++++++++
output: species A

input: Please answer the following: I read this background article the other day: Shown in the Figure below is a cylinder of gas on the left that is at room temperature (300 K). On the right, the cylinder has been heated until the Kelvin temperature has doubled to 600 K. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles. Decreasing the temperature would have the opposite effect, and the pressure of an enclosed gas would decrease. I am facing a new situation today: Nicholas works in pest control, and needs to have a steady supply of nitrogen gas for his tools. He always keeps a closed container of nitrogen gas in his freezer, where the temperature is very low. Nicholas's neighbor, Justin, likes to grill in his backyard. Justin, therefore, always keeps a closed container of propane gas outside, where the temperature is high. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Molecules of which gas will collide against the walls of their respective container with less force?
++++++++++
output: nitrogen gas

input: Please answer the following: I read this background article the other day: The balls used in squash are small rubber balls that can differ in terms of diameter, weight and softness. These features determine the speed and bouncing amplitude of the ball, with softer balls being generally slower than the harder balls. The temperature of the ball also affects the amount of bounce: the warmer the ball, the more it bounces.[3] Because cold squash balls have little bounce, the squash balls are hit multiple times at the beginning of a game to warm them up. It also means that a game becomes gradually faster as it advances and that softer balls may be too slow to be used in colder climates.[4] I am facing a new situation today: Thomas and Joseph, two experienced squash players, are having a disagreement about which types of squash balls they should use in their match. Both have different preferences for the type of ball used. Joseph prefers a ball that bounces less and travels more slowly. Thomas, on the other hand, prefers a ball that travels more quickly and bounces more. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which player enjoys the speed of game more as it progresses?
++++++++++
output:
Thomas
