Question

chemical-emitting gases or solids from interior products and materials cause short-term or long-term adverse health effects.
to minimize these health issues, a designer should specify products and materials:
that have high levels of volatile organic compounds (vocs)
with oil-based paints
that have low levels of volatile organic compounds (vocs)
with urea-formaldehyde

Explanation:

Volatile organic compounds (VOCs), oil-based paints, and urea-formaldehyde are all chemical-emitting substances that cause adverse health effects. To minimize these issues, products with low levels of such emitters are needed.

Answer:

that have low levels of volatile organic compounds (VOCs)
