input question: Background: A mycorrhiza (Greek for "fungus roots") is a symbiotic association between a fungus and the roots of a plant. In a mycorrhizal association, the fungus may colonize the roots of a host plant by either growing directly into the root cells, or by growing around the root cells. This association provides the fungus with relatively constant and direct access to glucose, which the plant produces by photosynthesis. The mycelia of the fungi increase the surface area of the plant's root system. The larger surface area improves water and mineral nutrient absorption from the soil. Paragraph: Fox and Ken were two aspiring horticulturists. Ken studied more about plant pollination, while Fox studied about mycorrhizal fungi. Given the paragraph above, please answer correctly the following question: Which friend read more about the mycelia of the fungi increasing the surface area of the plant's root system????
output answer: Fox

input question: Background: The major zones in river ecosystems are determined by the river bed's gradient or by the velocity of the current. Faster moving turbulent water typically contains greater concentrations of dissolved oxygen, which supports greater biodiversity than the slow moving water of pools. These distinctions form the basis for the division of rivers into upland and lowland rivers. The food base of streams within riparian forests is mostly derived from the trees, but wider streams and those that lack a canopy derive the majority of their food base from algae. Anadromous fish are also an important source of nutrients. Environmental threats to rivers include loss of water, dams, chemical pollution and introduced species. A dam produces negative effects that continue down the watershed. The most important negative effects are the reduction of spring flooding, which damages wetlands, and the retention of sediment, which leads to loss of deltaic wetlands. Paragraph: Two rivers spring from the same mountain. Olt was a fast moving river, while Mures river was slow moving and deep. Both rivers are very important for the local economies. Given the paragraph above, please answer correctly the following question: Which river had a food source mostly derived from algae????
output answer: Mures

input question: Background: Earthquakes may take place every day near a volcano. But before an eruption, the number and size of earthquakes increases. This is the result of magma pushing upward into the magma chamber. This motion causes stresses on neighboring rock to build up. Eventually the ground shakes. A continuous string of earthquakes may indicate that a volcano is about to erupt. Scientists use seismographs to record the length and strength of each earthquake. Paragraph: Two neighboring cities are situated in a volcanic area with lots of earthquakes. Park city is situated near a very active volcano, while Hill city is situated 50 miles north. Given the paragraph above, please answer correctly the following question: Which city experiences more motion causing stresses on neighboring rock to build up????
output answer: Park

input question: Background: 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. Paragraph: Two sisters took their blood pressure at the doctor's office. Jill had hypertension, while her sister Beth had normal blood pressure. Given the paragraph above, please answer correctly the following question: Which sister has to make diet changes????
output answer:
Jill
