Which term means impenetrable (as in gloves)?

• A. Gastrointestinal
• B. Impaired
• C. Impervious
• D. Infection

Answer: (C)

Understanding barrier properties in protective gear. Impervious describes a material that cannot be penetrated by liquids or pathogens, making it the right term for gloves designed to block fluids and keep threats from passing through. That shielding quality is what makes impervious the best fit for something described as impenetrable like gloves. In contrast, gastrointestinal relates to the digestive tract, impaired means not functioning properly, and infection refers to the presence of disease-causing organisms—none of these convey the idea of a barrier that cannot be penetrated.
