Question

The Kepler spacecraft was designed to investigate humanity’s last unexplored frontier: the far reaches of space. The NASA space telescope looks deep into the Milky Way galaxy for signs of habitable planets where humans could potentially thrive. In the thousands of planets, it has identified, three are in livable orbits similar to Earth.

The planet most similar to Earth is Kepler 186f, known as “Earth’s cousin.” Over 490 light years away, all that NASA knows is that Kepler 186f’s size and distance from its star are comparable to Earth. As technology advances, hopefully we will learn more about Kepler 186f’s ability to nurture life. Perhaps someday our descendants will cross the insurmountable distance to explore the surface of Earth’s cousin, maybe even contact with life on another world.

The following questions are based on this passage

16. Which of the following best describes the main idea of the second paragraph?

a. Scientists know many facts about the planet Kepler-186f

b. Conditions on Kepler-186f will allow humans to thrive

c. From what scientists have learned so far, Kepler 186f is the planet most similar to Earth

d. The Kepler space telescope’s main mission is to explore the Milky Way

17. Which of the following is evidence for the theory that Kepler -186f may be able to support life?

a. Kepler-186f will be the destination for our descendants someday

b. Kepler-186f is an unexplored frontier

c. Kepler-186f’s size and distance from its star is comparable to Earth

d. Kepler-186f is more than 490 light-years from Earth

18. Which word below best describes the author’s point of view in the passage?

a. Informative

b. Persuasive

c. Entertaining

d. Analytical

Answer 1

16)From the second paragraph we can understand that Kepler 186f is a planet which is most similar to earth and it is known as earth's cousin.

Option C is correct.

Scientists so far learned that Kepler 186f is a planet which is similar to earth.They did not explained that it will allow humans to thrive.

Option A is incorrect because scientists only know some facts about the planet.They do not know many things about the planet.

Option B is incorrect because there is no correct information about Kepler.So we cannot say the humans will thrive on it.

Option D is incorrect because there is no statement about Milky way in second paragraph.

17)from the information provided in paragraphs we can see that Kepler 186f is similar in size to earth.And it's distance from its star is comparable to earth.

So option C is correct.

Kepler 186f size and distance from star is comparable to earth.

Option A is incorrect because our descendants destination does not explain anything about planet ability to support life.

Option B is incorrect because there is no explanation which supports life about unexplored Frontier.

Option D is incorrect because Kepler 186f is 490 light years from earth and this sentence does not have any relevant explaining which makes us understand about the other planet ability to support life.

18)Option A is correct.

It is because author is explaining about another planet which can support life and it is similar to earth.

Option B is incorrect because the author does not use persuasion.

Option C is incorrect because the information is important but it is not entertaining.

Option D is incorrect because the author is not using analytical approach.
