Problem: Given the question: Background: 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 ). Paragraph: Two teams were competing in a 5 km race. White team warmed up before the race, but Blue team arrived with a bus late and didn't have time to warm up properly before the race. Given the paragraph above, please answer correctly the following question: Which team had fewer athletes with an increased heart rate before the race?
++++++++++++++++++++++++++++++++
The answer is:
Blue

Problem: Given the question: Background: Thermoclines, or sudden changes in temperature. Where the air temperature is higher than the water temperature, shallow water may be warmed by the air and the sunlight but deeper water remains cold resulting in a lowering of temperature as the diver descends. This temperature change may be concentrated over a small vertical interval, when it is called a thermocline.[3][4] Where cold, fresh water enters a warmer sea the fresh water may float over the denser saline water, so the temperature rises as the diver descends.[3] In lakes exposed to geothermal activity, the temperature of the deeper water may be warmer than the surface water. This will usually lead to convection currents.[3] Paragraph: Ryan explored two lakes; Big lake, and Arrow lake to the south. Arrow lake had a river flowing into it, while Big lake presented evidence of underwater geothermal activity. Many divers drowned in Arrow lake because of temperature shock. Given the paragraph above, please answer correctly the following question: Which lake had less of a temperature change concentrated over a small vertical interval?
++++++++++++++++++++++++++++++++
The answer is:
Big lake

Problem: Given the question: Background: Many respiratory diseases are caused by pathogens. A pathogen is an organism that causes disease in another organism. Certain bacteria, viruses, and fungi are pathogens of the respiratory system. The common cold and flu are caused by viruses. The influenza virus that causes the flu is pictured below ( Figure below ). Tuberculosis, whooping cough, and acute bronchitis are caused by bacteria. The pathogens that cause colds, flu, and TB can be passed from person to person by coughing, sneezing, and spitting. Illnesses caused by bacteria can be treated with antibiotics. Those caused by viruses cannot. Paragraph: Martin and David are roommates in their dorm room. Martin comes down with the flu and is very sick coughing and sneezing a lot. David opts to take care of Martin, spending a lot of time with him to make sure he gets well soon. Given the paragraph above, please answer correctly the following question: Given David decides to stay with his parents instead of taking care of Mathew, will his chances of getting the flu increase or decrease?
++++++++++++++++++++++++++++++++
The answer is:
decrease
