DOL - Solar System

What is the primary focus of the article?

• to explain the significance of space exploration throughout history.

• to discuss the process of how planets are formed in the solar system

• to describe the structure and various components of the solar system

• to provide information on how telescopes helped advance knowledge of space

How do paragraph 3 and 4 contribute to the development of ideas in the article? Select TWO correct answers.

• They introduce distant regions of the solar system that lie beyond the eight planets

• They explain why scientists study regions like the Kuiper Belt and Oort Cloud

• They discuss the mysteries surrounding the farthest parts of the solar system

• They describe remote regions of the solar system that are less familiar and farther from the sun.

What is the BEST paraphrase of paragraph 7?

• Materials in space collided and combined to form larger objects, such as planets, dwarf planets, and moons, while smaller fragments still move through the solar system.

• Materials far from the sun clumped together to form planets, but some pieces did not form planets and are still floating.

• In the outer solar system, materials smashed into each other, forming different planets, and moons, while some larger pieces continue to drift in space.

• Farther out, materials came together to create planets, moons, and dwarf planets, and other fragments are still flying.

What is the BEST summary of the selection "Exploring Our Solar System"?

Based on the information in the article, why might scientists continue to explore regions beyond our solar system?

• To search for Earth like planets and evaluate the possibility of life existing elsewhere in the universe

• To collect more evidence on the processes of solar system formation and assess if similar mechanisms operate in other star system

• To monitor the trajectories of distant asteroids and comets that could potentially impact planets within our solar system

• To investigate how distant regions, like the Kuiper Belt and Oort Cloud, might influence the stability and evolution of the inner planets.
