In these type of comparison questions look for an answer choice that shows the difference between two quantities that not similar and may be the cause of the conclusion.

see this question does a good job in repeating similar verbiage in all the answer choices, wasting your time.
I took weel above 2 mins as well

Mined-consumed= available

B , talks about the difference

straight B! Doesn't seem like a 700 level question. More of a mid 600 level.

Lets express the argument in terms of equation.

A-Available
M-Mined
C-Consumed

It is given that

A91+ M91 - C91 < A90
M91 - C91 < 0
M91 < C91

It is "could be" question...
The answer choice is a possible scenario. It must not be true!

No where in the argument, the author is saying that the coal mined in 1990 is used in 1991!
If the coal mined in 1990 is not usable due to some reasons, then option B will not be true!
To arrive at answer choice B, you have to assume that the coal produced in 1990 can be used in 1991! Hence this is "could be true" question -- not "must be true question.

We should be wary about such questions.. Such questions create just more confusion to the testers..

Please check option B. It is stated as the OA.

The stimulus states that Coal Available = Coal Mined - Coal Consumed

How can more coal be consumed than be mined in the same year?

Other than this option, every other option can be proven wrong. Please check both the question and its OA.

Thanks

This is possible because Country Q can have a stockpile of coal leftover from previous years. Perhaps Country Q had a huge supply of coal stored up in 1990. Theoretically, they could then use the coal from that supply in 1991, reducing or eliminating the need to mine for new coal.

The OA (B) is correct.

I hope that helps!

Each December 31 in Country Q, a tally is made of the country’s total available coal supplies—that is, the total 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.

If the statements above are true, which one of the following must also be true on the basis of them?

(A) In Country Q, more coal was mined in 1990 than was mined in 1991.
(B) In Country Q, the amount of coal consumed in 1991 was greater than the amount of coal mined in 1991.
(C) In Country Q, the amount of coal consumed in 1990 was greater than the amount of coal consumed in 1991.
(D) In Country Q, the amount of coal consumed in 1991 was greater than the amount of coal consumed in 1990.
(E) In Country Q, more coal was consumed during the first half of 1991 than was consumed during the first half of 1990.

The coal left without consumption is counted in the end of the year.
This extra coal is then consumed in the next year.

Option B is correct because it says that this years coal left is less than that left last year, this means that the production stays stable but the consumption has increaed because the left out coal is less than the coal left last year so that clearly measn the consumption has increased
