Answer :
Answer:
Correct Answer:
E. No new coal deposits have been discovered within Montania for the last fifteen years.
Explanation:
This option E would definitely weaken the coal executive argument because, most of the jobs were lost if there was no discovery of coal in the last 15 years. To most coal producer, it would be meaningless to keep most of the workers in payroll when there is no job available for them. Rather than incur losses, they would rather sack their workers thereby leading to decrease in number of coal workers.
