Question

1. storing toxic chemicals in metal drums is unwise because ______.

○ metal drums are themselves toxic
○ the drums contract
○ the chemicals cannot break down
○ the drums corrode

Explanation:

Toxic chemicals often have corrosive properties that react with metal, causing the drums to corrode. This leads to leaks of the toxic substances, making metal drums an unwise storage choice. The other options are incorrect: metal drums themselves are not toxic, drum contraction is not a relevant issue, and the inability of chemicals to break down is unrelated to the storage container material.

Answer:

○ the drums corrode
