Context: The passage below describes an experiment. Read the passage and then follow the instructions below.
Tom placed a ping pong ball in a catapult, pulled the catapult's arm back to a 45° angle, and launched the ball. Then, Tom launched another ping pong ball, this time pulling the catapult's arm back to a 30° angle. With each launch, his friend Justin measured the distance between the catapult and the place where the ball hit the ground. Tom and Justin repeated the launches with ping pong balls in four more identical catapults. They compared the distances the balls traveled when launched from a 45° angle to the distances the balls traveled when launched from a 30° angle.
Figure: a catapult for launching ping pong balls.
Identify the question that Tom and Justin's experiment can best answer.
A. Do ping pong balls stop rolling along the ground sooner after being launched from a 30° angle or a 45° angle?
B. Do ping pong balls travel farther when launched from a 30° angle compared to a 45° angle?

Context: The passage below describes an experiment. Read the passage and then follow the instructions below.
Kathleen applied a thin layer of wax to the underside of her snowboard and rode the board straight down a hill. Then, she removed the wax and rode the snowboard straight down the hill again. She repeated the rides four more times, alternating whether she rode with a thin layer of wax on the board or not. Her friend Bryant timed each ride. Kathleen and Bryant calculated the average time it took to slide straight down the hill on the snowboard with wax compared to the average time on the snowboard without wax.
Figure: snowboarding down a hill.

Context: This passage describes the myotonia congenita trait in goats:
Myotonia congenita is a condition that causes temporary muscle stiffness. When goats with myotonia congenita attempt to run from a resting position, their leg muscles often stiffen, causing them to fall over. Because of this behavior, these goats are referred to as fainting goats. Myotonia congenita is also found in other mammals, including horses, cats, and humans.
In a group of goats, some individuals have myotonia congenita and others do not. In this group, the gene for the myotonia congenita trait has two alleles. The allele for having myotonia congenita (M) is dominant over the allele for not having myotonia congenita (m).
This Punnett square shows a cross between two goats.
What is the probability that a goat produced by this cross will be homozygous dominant for the myotonia congenita gene?
A. 1/4
B. 0/4
C. 4/4
D. 2/4
E. 3/4

Context: The passage below describes an experiment. Read the passage and think about the variables that are described.
Pam was using steel to make rusted sculptures. After building each sculpture, she caused the steel in the sculpture to rust by placing it into a tub filled with salt water for eight hours. Pam wondered if steel would rust faster submerged in vinegar instead of salt water.
To find out, Pam cut ten squares of steel sheet metal and split them into two equal groups. She put one group of squares into a tub filled with salt water and the other group of squares into a tub filled with vinegar. Once an hour for eight hours, Pam counted the number of rusted steel squares in each group.

Context: The passage below describes an experiment. Read the passage and think about the variables that are described.
Rick often saw woodpeckers perched in trees in his backyard, but he never saw them at his bird feeders. Rick usually filled his feeders with sunflower seeds. He wondered if he could attract woodpeckers by adding a different type of food to the feeders.
To test this idea, Rick gathered eight identical bird feeders. He filled four with sunflower seeds. He filled the remaining four feeders with crushed peanuts. Rick then placed the bird feeders in his backyard. Over the next five days, he counted the number of woodpeckers that visited each bird feeder each morning.
Hint: An independent variable is a variable whose effect you are investigating. A dependent variable is a variable that you measure.
Figure: a woodpecker at a bird feeder.
Which of the following was an independent variable in this experiment?
A. the number of woodpeckers that visited the bird feeders
B. the type of food used in the bird feeders
