• Ⓑ It explains how wave energy works.

• Ⓒ It shows how wind and wave energy are different.

• Ⓓ It provides more information on fossil fuels.

This question has two parts. First, answer Part A. Then, answer Part B.

Part A

What is the overall text structure of the passage? 

• Ⓐ Chronology

• Ⓑ Comparison

• Ⓒ Cause and effect 

Part B

Which sentence from the text best supports compare and contrast

Ⓐ Since utilizing fossil fuels as our primary source of energy is not sustainable, we need to find an alternate, cleaner source of energy. (paragraph 2)

Ⓑ In today’s world, humans need more and more power in their everyday lives. (paragraph 1)

Ⓒ Wave energy is a lot like wind energy, which is captured through tall wind turbines. (paragraph 3) 

Ⓓ In addition, waves make a good source of energy because they are always moving. (paragraph 6)

This question has two parts. First, answer Part A. Then, answer Part B.

Part A

What is the author’s purpose? 

• Ⓐ to persuade people to continue to use up all fossil fuels

• Ⓑ to inform people the environmental dangers of fossil fuels

• Ⓒ to entertain people using jokes about energy

• Ⓓ to inform people of an alternative energy source to fossil fuels

Part B

Which of the following words or phrases does the author include to develop the purpose? 

• Ⓐ Fossil fuels are coal, oil, and gas. (paragraph 2)

• Ⓑ Humans are using Earth’s fossil fuels at a fast rate. (paragraph 2)

• Ⓒ These turbines work like windmills that get pushed by the wind’s force. (paragraph 3)

• Ⓓ In addition, waves make a good source of energy because they are always moving. (paragraph 6)

Part A

What claim is the author making in the text, Riding a Wave of Power? 

• Ⓐ Humans need to use less energy to conserve fossil fuels.

• Ⓑ Fossil fuels are a reliable and clean source of energy.

• Ⓒ Wind and wave energy are similar forms of energy.

• Ⓓ Wave energy is good replacement to fossil fuels.

Part B 

Which sentence from the passage supports the claim that the author makes? 

• Ⓐ “In today’s world, humans need more and more power in their everyday lives.” (paragraph 1)

• Ⓑ “They have formed over millions of years from the remains of living things.” (paragraph 2)

• Ⓒ “It is possible that one day we will use up Earth’s fossil fuels. However, the ocean will always be there.” (paragraph 5)

• Ⓓ “Wave energy is a lot like wind energy, which is captured through tall wind turbines.” (paragraph 3)

Select the best summary of the text, Riding a Wave of Power. 

 

• Ⓐ Humans need to conserve fossil fuels. There are only so many fossil fuels left on Earth. Utilizing wind and water energy will help make fossil fuels last longer.

• Ⓑ Wave energy is a good source of energy. Fossil fuels will not last forever and humans are in need of a clean energy source. Wave energy will never run out. Wave turbines do not give off pollution.

• Ⓒ Wind energy is similar to water energy. Both are good alternatives to fossil fuels. Wind and water energy both use turbines to create energy. 

• Ⓓ Moving buoys from waves push water into pumps. The pumped water helps drive the turbines. The spinning turbines create pollution-free energy. Used water gets placed back into the ocean

Select a statement that best describes a similarity in the way the author presents information about energy in both texts.

• Ⓐ Both authors present a brief history of energy usage.

• Ⓑ Both authors present information about how turbines work.

• Ⓒ Both authors present a brief history of why humans use fossil fuels.

• Ⓓ Both authors present information about wave energy.

Select a statement that best describes a difference in the way the author presents information about energy in both texts.

• Ⓐ In Riding a Wave of Power, the author presents the benefits and drawbacks of using wind energy.

• Ⓑ In Riding a Wave of Power, the author presents an alternative to using fossil fuels.

• Ⓒ In Riding a Wave of Power, the author provides reasons why wave power is a good idea.

• Ⓓ In Riding a Wave of Power,  the author explains that wave power has been used since ancient times.
