Question

In the past efforts to clean up oil spills have included which methods A. mopping and recapturing

b.spreading detergent and soaking
c. vacuuming and burning

Answer 1

The correct answer is C.
In the older times, any effort to deal with an oil spill in the ocean included a suction skimmer to collect the oil from the water surface and the oil was burned on site. A suction skimmer is attached to a vacuum unit or a pump and it is ideal when there is a large amount of oil to be collected. On-site burning was used to carefully get rid of the oil.
