Question

after reading the document \take a closer look\, identify the statement that best summarizes the central idea of the text.

all lenses are used to magnify objects.
the lens in your eye works like the lens of a camera.
there are two types of telescopes: refracting and reflecting.

Explanation:

• The first option is a broad and comprehensive statement. Lenses are indeed used in various devices (like microscopes, telescopes, cameras etc.) which aid in examining the world more closely.
• The second option is incorrect as not all lenses are for magnification (e.g., corrective lenses for vision may not be for magnification in the traditional sense).
• The third option is a specific example and not a central idea.
• The fourth option is about a particular type of device (telescopes) and their classification, not the central idea about lenses in general.

Answer:

Lenses are used in many devices that help people examine the world more closely.
