In the past the country of Malvernia has relied heavily on imported oil. Malvernia recently implemented a program to convert heating systems from oil to natural gas.

Malvernia produces more natural gas than it uses so it will probably reduce its reliance on imported oils if these trends continue. Reasoning Which option provides the information that it would be most useful to know in evaluating the argument In other words we are looking for the option which depending on whether it was answered yes or no would either most weaken or most strengthen the argument. The argument indicates that Malvernia will be using less oil for heating and will be producing more oil domestically.
