input: Please answer the following: You are given a new situation: Paul and Dirk were studying the human digestive system. paul studied more about the stomach, while Dirk studied more about the jejunum. and a hint : The jejunum is the second part of the small intestine, where most nutrients are absorbed into the blood. As shown in Figure below , the mucous membrane lining the jejunum is covered with millions of microscopic, fingerlike projections called villi (singular, villus). Villi contain many capillaries, and nutrients pass from the villi into the bloodstream through the capillaries. Because there are so many villi, they greatly increase the surface area for absorption. In fact, they make the inner surface of the small intestine as large as a tennis court! Please answer this question : Which student read more about villi?

output: Dirk

input: Please answer the following: You are given a new situation: Two groups of runners attended a 5k event downtown. Brown group warmed up properly before the race, but Red group did no such thing and suffered the consequences. and a hint : Sometimes muscles and tendons get injured when a person starts doing an activity before they have warmed up properly. A warm up is a slow increase in the intensity of a physical activity that prepares muscles for an activity. Warming up increases the blood flow to the muscles and increases the heart rate. Warmed-up muscles and tendons are less likely to get injured. For example, before running or playing soccer, a person might jog slowly to warm muscles and increase their heart rate. Even elite athletes need to warm up ( Figure below ). Please answer this question : Which group did a slow increase in the intensity of a physical activity?
++++++++++
output: Brown

input: Please answer the following: You are given a new situation: A waitress sets down two cups of water at a table and then takes the table's order. She leaves to place the order and the diners begin chatting and sipping on their water. Kim remarks that her water is room temperature and she wishes that it was cooler. Janet states that her water is so cold it hurts her teeth and wishes hers was warmer. They agree to mention it to the waitress when she returns. and a hint : Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4C. Please answer this question : Which person's water has molecules closer together?
++++++++++
output: Janet

input: Please answer the following: You are given a new situation: Two friends, John and Abe, worked at the same warehouse. John was exposed to very strong light all the time, while Abe worked in a more normal environment. John started experiencing health problems after a while. and a hint : Medical research on the effects of excessive light on the human body suggests that a variety of adverse health effects may be caused by light pollution or excessive light exposure, and some lighting design textbooks[33] use human health as an explicit criterion for proper interior lighting. Health effects of over-illumination or improper spectral composition of light may include: increased headache incidence, worker fatigue, medically defined stress, decrease in sexual function and increase in anxiety.[34][35][36][37] Likewise, animal models have been studied demonstrating unavoidable light to produce adverse effect on mood and anxiety.[38] For those who need to be awake at night, light at night also has an acute effect on alertness and mood.[39] Please answer this question : Which worker experienced stronger effects on alertness and mood, John or Abe?

output:
John
