Question

engineers tasked with building a car bumper need high - quality plastic that is readily available. they found the material polycarbonate, which is long - lasting and not too costly.
which is one technological design criterion they have already met?
\bigcirc be available
\bigcirc be attractive
\bigcirc be durable
\bigcirc be safe

Explanation:

1. Analyze the option "be available": The problem states the plastic is "readily available", but let's check other options too.
2. Analyze "be attractive": There is no mention of the bumper or plastic being attractive, so this is out.
3. Analyze "be durable": The material is described as "long - lasting", and durable means long - lasting. This fits.
4. Analyze "be safe": There is no information given about the safety of the polycarbonate for the car bumper, so this is not met.

Among the options, "be durable" is met as the material is long - lasting.

Answer:

be durable
