[Q]: Please answer correctly the following question related to the paragraph below. Which area will release less carbon dioxide, Xuejiang or Ontario? Xuejiang, a town in China, recently increased their levels of steel and construction materials production. The factories that produce these materials have been burning high levels of fossil fuels to support this production. Ontario, meanwhile, has been burning low levels of fossil fuels thanks to investment in alternative energies, and a general decrease in the manufacturing industries there. Hint: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth's temperature, known as global warming or global climate change.

[Q]: Please answer correctly the following question related to the paragraph below. Which farmer had fewer animals grazing in a shaded environment? Two farmers from the same village raised animals. The village was situated in a hot climate. They took the animals to graze on pastures nearby. Tom took his animals to a silvopasture, while Bill took his to a grassland. Hint: Trees can benefit fauna. The most common examples are silvopasture where cattle, goats, or sheep browse on grasses grown under trees. In hot climates, the animals are less stressed and put on weight faster when grazing in a cooler, shaded environment. The leaves of trees or shrubs can also serve as fodder.

[Q]: Please answer correctly the following question related to the paragraph below. Which person's car, Jacob's or Alejandro's, must have accelerated slower? Jacob is an avid street car racer who is driving in his sleek black Mustang. He comes to a red light and sees the car next to him is an expensive looking Honda Civic, owned by a man named Alejandro. Jacob and Alejandro agree to race, and when the light turns green they both slam their feet on the gas pedal and take off. Jacob's car arrives at the light pole down the street from the light sooner than Alejandro's car, and he wins the race. Hint: Acceleration is a measure of the change in velocity of a moving object. It measures the rate at which velocity changes. Velocity, in turn, is a measure of the speed and direction of motion, so a change in velocity may reflect a change in speed, a change in direction, or both. Both velocity and acceleration are vectors. A vector is any measurement that has both size and direction. People commonly think of acceleration as in increase in speed, but a decrease in speed is also acceleration. In this case, acceleration is negative and called deceleration. A change in direction without a change in speed is acceleration as well.

[Q]: Please answer correctly the following question related to the paragraph below. Which patient would secrete more insulin, patient A or patient B? Rob is studying medicine in a prestigious university. Today, his professor is teaching about blood glucose levels. He gave example of two patients, patient A and patient B. Patient A had high blood glucose level, but patient B had low blood glucose level. Rob was amazed to find how body keeps its balance. Hint: Another example of negative feedback has to do with blood glucose levels. When glucose (sugar) levels in the blood are too high, the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen, which is stored in the liver. As blood glucose levels decrease, less insulin is produced. When glucose levels are too low, another hormone called glucagon is produced, which causes the liver to convert glycogen back to glucose.
