Question

Read the excerpt from Chapter Two of Windows to the Universe: Revolutions in Astronomy.

Eventually, telescopes became essential tools for exploring the universe, leading to even more incredible discoveries. But sometimes, despite all the technological advances made over the centuries, even the most cutting-edge telescopes encounter major problems.

Why does the author most likely include this information at the end of the chapter instead of at the beginning?

to offer new evidence supporting the idea that challenges faced by early telescope inventors remain unresolved
to summarize the chapter's main ideas while hinting at future topics in subsequent chapters
to critique the effectiveness of modern telescopes compared to historical designs
to provide a detailed explanation of problems with telescopes that the chapter failed to address earlier

Answer 1

to summarize the chapter's main ideas while hinting at future topics in subsequent chapters

This sentence wraps up the chapter by noting telescopes' importance and introducing the idea that even modern instruments can have problems, which both reinforces the chapter's themes and sets up discussion in later chapters.
