Which pairing correctly identifies a common VT error source and its mitigation?

• A. Poor lighting — randomized lighting changes.
• B. Glare — adjust angles.
• C. Inconsistent distance — vary the stand-off distance.
• D. Subjective sizing — ignore references.

Answer: (B)

Glare comes from bright reflections on shiny surfaces and can wash out important details. The most effective way to deal with it is to change the geometry of illumination and viewing so the specular reflection no longer enters the observer’s line of sight. That means adjusting the light’s angle or the viewing angle (or both) to move the glare away, often aided by diffused lighting or a polarizer. This directly reduces glare and makes defects easier to see.

Other options don’t address glare consistently. Random lighting changes won’t reliably remove glare and can create new issues; changing stand-off distance affects focus and scale rather than glare; ignoring references or subjective sizing is simply poor practice and does not mitigate glare.
