Question

metals are usually good ____ of electricity, and are generally wrapped in a(n) ____ like rubber or plastic when used in wiring for safety.
(1 point)

○ acceptors, opposer

○ conductors, insulator

○ opposers, acceptor

○ insulators, conductor

Explanation:

To solve this, we recall the definitions of electrical conductors and insulators. Conductors are materials (like metals) that allow electricity to flow through them easily. Insulators are materials (like rubber or plastic) that resist the flow of electricity, which is why they're used to wrap wires for safety.

• "Acceptors" and "opposer" are not standard terms for electrical properties.
• "Opposers" and "acceptor" also don't fit the context.
• "Insulators, conductor" is reversed because metals are conductors, not insulators, and the wrapping should be an insulator.

So the correct pair is "conductors, insulator".

Answer:

B. conductors, insulator (assuming the option with "conductors, insulator" is labeled as such; from the options, the second option is "conductors, insulator")
