Answer

Brief Explanations:

The excerpt uses terms like "refracting telescopes", "reflecting telescopes", "pure, bubble - free glass", "parabolic curves" and explains how mistakes in shaping or polishing affect images. This use of technical terms and explanations gives an informative tone.

Answer:

by including technical terms and explanations about telescope construction
