Reading Advance day 9

According to the passage, why is KOI 7711.01 considered one of the most Earth-like planets discovered so far?

• It is the smallest planet ever discovered.

• It orbits a star identical to the sun.

• It receives a similar amount of heat from its star as Earth does.

• It is the closest exoplanet to Earth.

What can be inferred about the significance of Kepler’s discoveries regarding potentially habitable planets?

• Kepler proved that Earth is unique in the galaxy.

• Kepler suggested that most exoplanets are gas giants.

• Kepler’s discoveries imply that habitable planets may be common in the galaxy.

• Kepler established that liquid water exists on all rocky planets.

The word "demography" in the sentence, “...putting together a census of various otherworldly populations rather than focusing on individual curiosities,” most closely means:

• Analysis of age and size.

• Study of statistical data about groups.

• Categorization of individual anomalies.

• Exploration of unusual behaviors.

What method did the Kepler telescope use to detect planets?

• Measuring gravitational forces between planets and stars.

• Observing changes in star brightness when planets pass in front of them.

• Scanning for radio signals emitted by alien civilizations.

• Using thermal imaging to identify heat signatures of planets.

What is the main purpose of the author’s description of Kepler’s small field of study?

• To emphasize the telescope’s technological limitations.

• To highlight the vast number of potential planets in the galaxy.

• To criticize the narrow focus of the Kepler mission.

• To explain why the Kepler mission lasted only four years.

Why does Susan Thompson caution against calling KOI 7711.01 an "Earth twin"?

• Because its temperature is far higher than Earth’s.

• Because its size is vastly different from Earth’s.

• Because little is known about its atmosphere and presence of water.

• Because it is located too far from Earth for further study.

Which of the following best restates the sentence, “The spacecraft could only spot planets whose orbits put them between Earth and their stars”?

• Kepler could detect all planets in a planetary system.

• Kepler identified planets that passed directly in front of their stars from Earth’s viewpoint.

• Kepler was able to see planets only when they emitted light toward Earth.

• Kepler observed planets that orbited Earth rather than their stars.

Based on the information in the passage, how does the discovery of 50 potentially habitable planets affect our understanding of the galaxy?

• It shows that most planets are uninhabitable.

• It suggests that habitable planets are rare even in small areas of space.

• It indicates the existence of billions of potentially habitable planets in the galaxy.

• It proves that liquid water is common on exoplanets.

Which statement best summarizes the main idea of the passage?

• NASA’s Kepler telescope has confirmed over 4,000 exoplanets in the past decade.

• Kepler’s discoveries have revolutionized our understanding of habitable planets, suggesting billions of Earth-like worlds could exist in the galaxy.

• KOI 7711.01 is the closest confirmed Earth-like planet in our galaxy.

• The Kepler telescope has focused on finding rocky planets outside our solar system.

Considering the discoveries mentioned in the passage, what would be the logical next step in studying potentially habitable planets?

• Launching a telescope to detect gravitational forces of exoplanets.

• Developing instruments to analyze the atmospheres of Earth-like planets.

• Searching for intelligent lifeforms on planets similar to KOI 7711.01.

• Expanding the Kepler mission to study a broader area of the sky.
