[Q]: Please answer correctly the following question related to the paragraph below. Which person will have a harder time breathing at the top of the mountain, Mark or Jordan? Mark and Jordan want to take a trip together. Mark wants to go mountain climbing while Jordan wants to go to a concert out of state. Jordan sometimes has a hard time breathing as well so they take this into consideration while making the plans for their trip. Hint: As shown here, pressure decreases to less than 25% of ground-level atmospheric pressure when we get to an altitude of about six miles. Since this is a common cruising altitude for commercial airplanes, pressurized cabins are needed for the comfort and survival of the passengers. This is because the density of the air decreases along with the decreasing air pressure, so there is less oxygen in a breath of air. You've probably noticed this effect in high-mountain areas, as it often feels harder to breath.

[Q]: Please answer correctly the following question related to the paragraph below. Which student didn't have to delay any disease using proper medication? Two college students both had unprotected sex with different partners. Ben got the HIV virus, while Nate was lucky and was not infected with any diseases. Hint: HIV , or human immunodeficiency virus, causes AIDS. AIDS stands for "acquired immune deficiency syndrome." It is a condition that causes death and does not have a known cure. AIDS usually develops 10 to 15 years after a person is first infected with HIV. The development of AIDS can be delayed with proper medicines. The delay can be well over 20 years with the right medicines. Today, individuals who acquire HIV after 50 years of age can expect to reach an average human life span.

[Q]: Please answer correctly the following question related to the paragraph below. Which farmer didn't use a bacterium that produces a protein that can act as an insecticide? Two farmers tried different methods of growing their crops. Nate used pesticides, while his buddy Don used bacterium that produces a toxin instead. Don was happy with the results. Hint: There is growing concern regarding the use of pesticides in agriculture. Therefore, many of the current commercial applications of modern biotechnology in agriculture are focused on reducing the dependence of farmers on these chemicals. For example, Bacillus thuringiensis (Bt) is a soil bacterium that produces a protein that can act as an insecticide, known as the Bt toxin . But it is a naturally occurring protein, not a foreign chemical. Could this protein be used in crops instead of pesticides? Traditionally, an insecticidal spray has been produced from these bacteria. As a spray, the Bt toxin is in an inactive state and requires digestion by an insect to become active and have any effect. Crop plants have now been engineered to contain and express the genes for the Bt toxin, which they produce in its active form. When an insect ingests the transgenic crop, it stops feeding and soon thereafter dies as a result of the Bt toxin binding to its gut wall. Bt corn is now commercially available in a number of countries to control corn borer (an insect like a moth or butterfly), which is otherwise controlled by insecticidal spraying.

[Q]: Please answer correctly the following question related to the paragraph below. Which city has more fog during summer? Sam lived in Chicago for many years and experienced those high humidity days during the summer, the Indian summers in October and harsh and humid winters, so he decided to move to San Diego, in a warmer and much dryer climate. Hint: If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls. This is because less vapor is needed to saturate the air, so vapor condenses as the temperature falls. In normal conditions, the dew point temperature will not be greater than the air temperature because relative humidity cannot exceed 100%.[4]
