Some mirrors are convex.

Some mirrors are convex.

• A. All mirrors are flat
• B. Mirrors on both sides are adjustable
• C. Mirrors are always convex
• D. Some mirrors are convex

Answer: (D)

The idea here is that mirrors come in different shapes, and convex mirrors are used because they give you a wider field of view. A convex mirror is curved outward, which lets you see more of the road and surrounding traffic with a single glance. That broader view helps reduce blind spots, which is why many mirrors are convex on motorcycles. However, not all mirrors are convex—there are flat mirrors too and sometimes other shapes. So the statement that some mirrors are convex is true and best reflects how mirrors are actually used. The other options claim universal properties (all mirrors are flat, mirrors on both sides must be adjustable, or mirrors are always convex) that don’t hold in real-world practice.
