- Offshore oil-drilling operations involve an unavoidable risk of an oil spill, but importing oil on tankers presently involves an even greater such risk per barrel of oil.
Question 1:
Offshore oil-drilling operations involve an unavoidable risk of an oil spill, but importing oil on tankers presently involves an even greater such risk per barrel of oil. So, if we are to lessen the risk of an oil spill without reducing our oil usage, we must invest more in offshore operations and import less oil on tankers.Which of the following, if true, seriously weakens the argument above?
A. Importing oil on tankers is currently less expensive than drilling for it offshore.
B. Tankers can easily be redesigned so that their use entails less risk of an oil spill.
Feedback We have to go against investment in offshore drilling and support importing oil on tankers. In that case, the argument is weakened because the lowered risk of oil spills resulting from improved oil tanker design could actually make tankers less problematic than offshore operations.
C. The impact of offshore operations on the environment can be reduced by careful management.
D. Oil spills caused by tankers have generally been more serious than those caused by offshore operations.
