Problem: Given the question: Background: Hemophilia is the name of a group of hereditary diseases that affect the body's ability to control blood clotting. Hemophilia is caused by a lack of clotting factors in the blood. Clotting factors are normally released by platelets. Since people with hemophilia cannot produce clots, any cut can put a person at risk of bleeding to death. The risk of internal bleeding is also increased in hemophilia, especially into muscles and joints. This disease affected the royal families of Europe. Paragraph: Two cousins went for a blood test. Tim found out he had hemophilia, while John was normal. Tim had to start taking medication. Given the paragraph above, please answer correctly the following question: Which cousin had an increased risk of bleeding into muscles?
++++++++++++++++++++++++++++++++
The answer is:
Tim

Problem: Given the question: Background: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it. Paragraph: Michael has become bored with his passive life style, and has decided to take up weight lifting as a hobby. He begins to exercise with weights several times a week. Michael's brother, Robert, isn't as motivated as Michael though. Robert decides to continue being mostly inactive and only exercises with weights every couple of months. Given the paragraph above, please answer correctly the following question: Who will increase the size of their muscles less?
++++++++++++++++++++++++++++++++
The answer is:
Robert

Problem: Given the question: Background: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. It's rate of loss has slowed with restrictions on pollutants, but it is still at risk. Paragraph: Two neighboring planets identical to Earth in size and atmospheric conditions behaved differently towards their environments. Planet A emitted a lot of air pollution, destroying its ozone layer, while Planet B respected the environment and used ecological products. Given the paragraph above, please answer correctly the following question: Which planet had higher levels of UV reaching it?
++++++++++++++++++++++++++++++++
The answer is:
Planet A
