Read the excerpt from Chapter Two of Windows to the Universe: Revolutions in Astronomy.In 1608, a Dutch spectacle maker named Jacob Metius filed the first patent for a device that could make "faraway objects appear close." His invention provided magnification three to four times. While the patent office denied his application (since it was easy to copy), Metius was awarded a small sum for his efforts. This simple invention—a long tube with a convex lens on one end and a concave lens on the other—was revolutionary.In the last sentence, why did the author most likely include "a long tube with a convex lens on one end and a concave lens on the other"?
Answer
A
to provide a transition that connects Metius's invention to broader advancements in telescope technology discussed later in the chapter
B
to contrast the simplicity of Metius's design with the more advanced telescope designs described later in the text
C
to provide a technical explanation of how Metius's invention inspired future telescope designs
D
to reinforce the significance of Metius's invention by emphasizing the simplicity of the design
