Passage
In nature, different types of organisms often form symbiotic (mutually beneficial) relationships with each other.
One such example of this is between certain types of fungi and plants; this relationship is known as a mycorrhiza. The association provides the fungus with food through access to sugars from photosynthesis in the plant. In return, the plant gains the use of the fungi’s surface area to absorb mineral nutrients from the soil. It is believed that without the assistance of fungi, these plants would not be able to absorb crucial nutrients, including phosphates, from the soil.
Two experiments were performed to study the effect that the plant-fungi relationship has on plant growth.
Experiment 1
For 6 weeks, several specimens of three different types of plants, selected from among four different types of plants, were grown in a greenhouse. The average growth of each type of plant was recorded every two weeks. The soil used for the plants was treated to remove any trace of fungi to establish expected growth without the plant-fungi association. The results are shown in Table 1.

Experiment 2
In this experiment, several specimens of four different types of plants were grown in a greenhouse for six weeks, and the average growth of each type of plant was recorded every two weeks. This time, however, untreated soil that contained fungi was used. The results are shown in Table 2.

Information on the plant types used is given in Table 3.
Q. The results of Experiment 1 indicate that during what time frame did all of the plant types studied experience the greatest increase in growth rate?
  • a)
    0–2 weeks
  • b)
    2–4 weeks
  • c)
    4–6 weeks
  • d)
    Cannot be determined from the given information
Correct answer is option 'B'. Can you explain this answer?

To answer this question, you must look at Table 1 and determine the amount of growth for each week.
Plant type 1: Week 0–2: 1.2 − 0 = 1.2 in.
                    Week 2–4: 2.8 − 1.2 = 1.6 in.
                    Week 4–6: 3.7 − 2.8 = 1.1 in.
Plant type 3: Week 0–2: 0.6 − 0 = 0.6 in.
                    Week 2–4: 1.7 − 0.6 = 1.1 in.
                    Week 4–6: 2.0 − 1.7 = 0.3 in.
Plant type 4: Week 0–2: 0.9 − 0 = 0.9 in.
                     Week 2–4: 2.6 − 0.9 = 1.5 in.
                     Week 4–6: 3.5 − 2.6 = 0.9 in.
In all three plant types, the greatest growth occurred between Weeks 2 and 4.

Directions:Read the passages and choose the best answer to each question.PassageNear the end of the 19th century, British engineer Osborne Reynolds ran a set of experiments to observe and predict the transition between laminar (steady) and turbulent flow of a liquid through a pipe. In Reynolds’ experiments, dye was forced through a liquid to show visually when the flow changed from laminar to turbulent. Laminar flow is common only in cases in which the flow channel is relatively small, the fluid is moving slowly, and its viscosity (the degree to which a fluid resists flow under an applied forc e) is relatively high. In turbulent flow, the speed of the fluid at any given point is continuously undergoing changes in both magnitude and direction. Reynolds demonstrated that the transition from laminar to turbulent flow in a pipe depends upon the value of a mathematical quantity equal to the velocity of flow (V ) times the diameter of the tube (D) times the mass density (ρ) of the fluid divided by its absolute viscosity (µ). The “Reynolds number,” as it is called, is determined by the following equation:Several students designed similar experiments to observe flow rates of different liquids. To conduct the experiments, the students were given the following apparatus: Liquid supply tank with clear test section tube and ‘bell mouth’ entrance 1 Rotameter to measure the velocity of flow (flow rate) Tap water • Motor oil 4, 10-ft long smooth pipes of various diameters: 0.25-inch, 0.50-inch, 0.75-inch, 1.0-inchFigure 1 illustrates an approximation of the set-up of each experiment.Figure 2 shows approximate viscosities of the water and motor oils used in the experiments.Experiment 1In Experiment 1, students began with a pipe of diameter 0.25 inches. The pipe was set first at a 15° angle and tap water was released steadily from the tank into the pipe. The velocity of flow (V) was measured. The pipe was then set at a 30° angle, a 45° angle, and a 60° angle, water was released steadily from the tank into the pipe, and the velocity of flow was measured. The process was then repeated for each diameter of pipe using the same amount of water each time. All data were recorded in Table 1. Temperature of the water was held constant at 20°C.Experiment 2In the second experiment, the tap water was replaced by Motor Oil A and the processes were repeated. The results are given in Table 2.Experiment 3In a third experiment, the tap water was replaced by Motor Oil B and the processes were repeated.Q.Information in the passage and the results of the experiments indicate which of the following? Compared to tap water, Motor Oil A
