Problem: Please answer correctly the following question related to the paragraph below. Which planet probably has less trees? Milton has just discovered two new planets while looking through his telescope. Luckily, he has invented a device that allows him to analyze far away planets from the comfort of his own home. He boots up the device and discovers that while these two planets are very similar, planet A has much more carbon dioxide in its atmosphere than planet B. While looking through his telescope, he is also able to see that there is the same race of intelligent creatures on both planets. Milton plans to write to his local observatory about his discovery. Hint: Carbon dioxide is the most significant long-lived greenhouse gas in Earth's atmosphere. Since the Industrial Revolution anthropogenic emissions primarily from use of fossil fuels and deforestation have rapidly increased its concentration in the atmosphere, leading to global warming. Carbon dioxide also causes ocean acidification because it dissolves in water to form carbonic acid.

A: planet A

Problem: Please answer correctly the following question related to the paragraph below. Which patient would see less build up in the inner walls of the arteries, patient A or patient B? John is a doctor with the local hospital. Earlier today, he was seeing two patients, patient A and patient B. John found out that patient A had more LDL, but patient B had more HDL. He now needs to determine correct treatment for them. Hint: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol.

A: patient B

Problem: Please answer correctly the following question related to the paragraph below. Are the particles in Beaker X more or less likely to bump into each other than the particles in Beaker A? Two identical chemical compounds are both in beakers on top of burners in a laboratory. Beaker A is sitting on top of a burner that is set to a low temperature, and Beaker X is on a burner with a high temperature. Ken, the scientist studying these compounds, is closely monitoring the chemicals to see what type of changes occur. Hint: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage.

A: more

Problem: Please answer correctly the following question related to the paragraph below. Which garden soil had higher salinity? Jim had a small veggie garden that he planted every year. His brother Rob had a similar patch, and he was also a gardener. The plants in Jim's garden started wilting at some point and he found out that his soil had high salinity and some harmful bacteria that wiled the plants indirectly. Rob's plant were ok, because he adjusted the soil's ph with sweet lime. Hint: Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions. Lower water availability may result from: drought conditions, where the soil moisture drops below conditions most favorable for plant functioning; the temperature falls to the point where the plants vascular system can not function. high salinity, which causes water to diffuse from the plant cells and induce shrinkage; saturated soil conditions, where roots are unable to obtain sufficient oxygen for cellular respiration, and so are unable to transport water into the plant; or bacteria or fungi that clog the plant's vascular system. Wilting diminishes the plant's ability to transpire and grow. Permanent wilting leads to plant death. Symptoms of wilting and blights resemble one another.
