input question: Two teams of researchers studied the environment in Antarctica. Team Black studied air pollution and the ozone layer, Team Red studied the water.  Given the paragraph above, please answer correctly the following question:   Which team observed higher levels of UV reaching Earth?  Hint: 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. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk.???

input question: Two brothers had bike repair shops in neighboring towns. Bob's was located in a hilly area, with more precipitation and full of bike trails, so he had more people coming in, while Rob's was in the valley, near the parks.  Given the paragraph above, please answer correctly the following question:   Which town had more cyclists riding in slippery conditions?  Hint: In slippery conditions some riders prefer to ride fixed because they believe the transmission provides increased feedback on back tire grip. However, there is also an increased risk of loss of control in such conditions. This is especially so when taking into account the large number of riders who ride brakeless. These riders must brake entirely through the drivetrain. Ideally this is done by resisting the forward motion of the pedals, shedding speed while the bike is still moving. Alternatively, though far less efficiently, one can brake by stopping the motion of the pedals in mid-rotation, causing the rear wheel to lock in place, allowing the bicycle to skid and slow down from kinetic friction (see below).[22]  Descending any significant gradient is more difficult as the rider must spin the cranks at high speed (sometimes at 170 rpm or more), or use the brakes to slow down. Some consider that the enforced fast spin when descending increases suppleness or flexibility, which is said to improve pedalling performance on any type of bicycle; however the performance boost is negligible compared to the benefits of riding a free wheel.[23]???

input question: Tom and Jerry were two 50-year-olds which went to high-school together. They recently met and discussed their health problems over coffee. Tom had hypertension and the doc told him to change his diet.  Given the paragraph above, please answer correctly the following question:   Which friend had to start drinking skim milk?  Hint: Hypertension , which is also called "high blood pressure," occurs when a person’s blood pressure is always high. Hypertension is said to be present when a person's systolic blood pressure is always 140 or higher, and/or if the person's diastolic blood pressure is always 90 or higher. Having hypertension increases a person’s chance for developing heart disease, having a stroke, or suffering from other serious cardiovascular diseases. Hypertension often does not have any symptoms, so a person may not know that he or she has high blood pressure. For this reason, hypertension is often called the "silent killer." Treatments for hypertension include diet changes, exercise, and medication. Foods thought to lower blood pressure include skim milk, spinach, beans, bananas and dark chocolate.???

input question: Bill and Bob were two brothers. they were both into physical exercise, but Bill chose weight lifting, and Bob running.  Given the paragraph above, please answer correctly the following question:   Which brother had more muscles contract against a resisting force?  Hint: 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 weaker—so use it or lose it.???
