Each December 31 in Country Q, a tally is made of the country's total available coal supplies-that is the amount of coal that has been mined throughout the country but not consumed. In 1991 that amount was considerably lower than it had been in 1990. Furthermore, Country Q has not imported or exported coal since 1970.
b) RIGHT ANSWER. in country Q the amount of coal consumed in 1991 was greater than the amount of coal mined in 1991.
I don't understand why this must be. What if country Q mined 5 million lbs of coal and consumed only 2 million lbs. This would leave 3 million lbs of available coal supplies and which could still be considerably lower than 1990's number. I do however, leave open the possibiblity that I have been studying too long and the answer could be obvious and I am missing it due to lack of sleep. Anyways, apprecitate any help!
