8. Engineers at a major automobile company developed five new fuel systems. The systems were designed
to decrease emissions and improve gas mileage.
The scientists ran an experiment to test the new fuel systems. All the systems were placed in separate,
identical trucks. The trucks were then driven in identical conditions to test the effectiveness of the systems.
A truck with a standard fuel system was also driven in the experiment as a control. The results of the
experiment are shown in the table below.

A scientist observed the number of deer that came to drink at a local pond on five different days. The table
above shows the data that she collected on those days.
Which of the following is supported by evidence seen in the data?

21. Plants tend to grow toward light. This is why plants placed on a sunny windowsill grow toward the
window rather than experiencing a more even growth pattern.
Mrs. Fairchild wants her houseplants to grow more evenly. She wonders if turning the houseplants will
encourage even growth, but she doesn't know how often she needs to turn the plant, so she sets up the
following experiment.
Mrs. Fairchild purchases four identical plants. Each plant is about the same height and has the same type of
pot with the same type and amount of soil. She places a stick into each pot near the stems of the plants. The
vertical sticks form a right angle with the top of the soil.
Next, she places all four plants on the same windowsill, so they all receive the same amount of light each
day. She leaves Plant one in the same position throughout the experiment. She turns Plant two 180 degrees
every 12 hours, Plant three 180 degrees every 24 hours, and Plant four 180 degrees every 48 hours.
Mrs. Fairchild monitors the plants daily. She counts the number of leaves on each side of the plant, and she
uses a protractor to measure how far each plant is leaning away from its stick.
What is the test variable (independent variable) in the experiment?
A. the distance that the plants leaned from the vertical stick
B. the number of leaves on each side of the plant
C. the type of plant that was used
D. the amount of time that passed between turnings
