Practice Test Questions Subtest II

Question 1

A student has a bag containing 96 hard candies and wants to give an equal number of them to each of 6 friends. Which of the following mathematical operations would be most useful for the student to use when determining how many candies each friend should receive?

a. addition
b. division
c. subtraction
d. multiplication

Answer 1

B. This question requires the examinee to demonstrate knowledge of operations. The operation of division can be defined as partitioning a certain number of items into a specified number of groups in order to determine how many items each group contains.

Question 2

A member of a local environmental group uses a spreadsheet to track the amount of paper, plastic, glass, and aluminum a community recycles each month, as shown below. The spreadsheet software can automatically create several types of graphs from the data. Which of the following types of graphs would be most appropriate for visually representing the percentages of the various recycled materials relative to the total amount recycled?

a. Circle Graph
b. Line Graph
c. Bar Graph
d. Scatter Plot

Answer 2

a. This question requires the examinee to apply knowledge of graphs to represent real-world situations. A circle graph is used to compare the parts of a whole and the area of each sector is proportional to the fraction or percentage of the area of the circle that it represents.

Question 3

[0, 1, 5, 14, 30, 55, . . .] Which of the following numbers would appear next in the patterned sequence above?

a. 64
b. 81
c. 91
d. 121

Answer 3

C. This question requires the examinee to recognize patterns in numbers. In the pattern given, the differences between the successive terms in the pattern are 1, 4, 9, 16, and 25, which are the squares of the first 5 integers. To determine the next term, the square of 6, or 36, must be added to 55 to get 91

Question 4

Two rectangles, A and B, are similar. Rectangle A has a length of 100 centimeters and a width of 50 centimeters. If the area of rectangle B is 200 square centimeters, what is its perimeter?

a. 40 centimeters
b. 60 centimeters
c. 80 centimeters
d. 120 centimeters

Answer 4

B. This question requires the examinee to solve problems involving perimeter. If rectangles A and B are similar, the length and width of rectangle B must be proportional to the length and width of rectangle A. In addition, the product of the length and width of rectangle B must equal 200 square centimeters. If the length of rectangle B is 20 centimeters and its width is 10 centimeters, both of these conditions are met. Therefore, the equation representing the perimeter of rectangle B is 20 + 10 + 20 + 10 = 60.

Question 5

The waxy layer covering the exoskeleton of an insect is an adaptation that primarily aids in which of the following functions?

a. absorbing oxygen
b. avoiding detection by predators
c. minimizing water loss
d. blocking ultraviolet radiation

Answer 5

C. This question requires the examinee to apply knowledge of the characteristics of living organisms. In terrestrial insects, the waxy layer of the exoskeleton acts as a waterproof barrier that keeps water in and prevents insects from becoming dehydrated.

Question 6

Which of the following shows the relative positions of the sun, Earth, and moon during a solar eclipse?

Answer 6

A. This question requires the examinee to recognize the effects of the relative positions of the sun, Earth, and moon. A solar eclipse can only occur when the moon moves directly between the sun and Earth, casting its shadow over part of Earth.

Question 7

The relationship between form and function is a common theme in science. For example, the specific type of chemical bonding between copper atoms is what is responsible for the high electrical conductivity and ductility of this metal. Which of the following is another example of this relationship?

a. the expression of human genes in bacterial cells
b. the differences in weathering patterns caused by wind and water
c. the shape of plant leaves in the understory of a tropical rain forest
d. the jigsaw puzzlelike characteristics of the continents

Answer 7

C. This question requires the examinee to recognize the relationship between form and function. Plant leaves in the understory of a tropical rain forest are usually large in order to capture as much sunlight as possible, and they often have drip tips to help excess precipitation run off.

Question 8

In dramatic literature, which of the following is a common characteristic of plays that are classified as tragedies?

a. a story line that ridicules a situation in society for the purpose of improving it
b. stock characters who represent particular personality types
c. a clear and unchanging view of right and wrong
d. a main character who makes an error that leads to inevitable consequences

Answer 8

D. This question requires the examinee to identify basic terms associated with drama. Tragedy is a serious dramatic form that has a sorrowful or disastrous conclusion in which a central character suffers some misfortune that is logically connected to the character’s actions.

Question 40

A food web is more realistic than a food chain for showing the feeding relationships in ecosystems because:

food webs represent biological systems that are much more complicated than can be represented by a simple chain.

the food web’s triangular shape makes it easier for someone to distinguish between energy producers and energy consumers.

food chains represent biological systems that are much more complicated than can be represented by a simple web.

it is impossible for food chains to describe aquatic ecosystems.

food webs represent biological systems that are much more complicated than can be represented by a simple chain.

Question 41

If you move a substance from one container to another and its volume changes, the substance is a

1. solution.
2. liquid.
3. gas.
4. solid.

Answer 41

3. Gas

Gases expand to fill their containers. For example, if you had one liter of a gas, such as nitrogen, and you pumped it into a 2-liter jar, the gas would swell to fill up the whole 2 liters.

Question 42

Which of the following is supportive evidence of the Big Bang theory?

1. existence of nebulae
2. cosmic microwave background radiation
3. galactic star clusters
4. different shapes of galaxies

Answer 42

2. cosmic microwave background radiation

In 1964, two scientists, Arno Penzias and Robert Wilson, in an attempt to detect microwaves from outer space, inadvertently experienced a bothersome noise that came from all directions. It soon became obvious that what they heard was microwave background radiation from the farthest reaches of the universe that had been left over from the Big Bang. This discovery of the radioactive aftermath of the initial explosion lent much support to the Big Bang theory.
