Question

which change might be made to a cars front windshield to help a person drive? a a windshield may have a special kind of wax on it that keeps it clean at all times. b a windshield may have special boxes that pop up in it to warn drivers of danger. c a windshield may be made of plastic instead of glass. d a windshield may be smaller so only the driver can see through it.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: A special wax that keeps the windshield clean at all times would improve visibility, which is crucial for safe driving. This is a practical and reasonable change.
• Option B: Having special boxes pop up in the windshield would obstruct the driver's view, which is unsafe and not a helpful change for driving.
• Option C: Replacing glass with plastic for the windshield is not a typical or beneficial change for driving; glass is commonly used for its optical clarity and safety properties (like shattering in a way that's less dangerous), and plastic may not offer the same visibility or safety.
• Option D: Making the windshield smaller so only the driver can see through it would severely limit visibility for the driver and is completely impractical and unsafe for driving.

So, the only change that helps a person drive is the one in Option A.

Answer:

A. A windshield may have a special kind of wax on it that keeps it clean at all times.
