All that shows up is code that most likely is referenced to create the practice problem. There are no answers to select from. The text looks like this:
"Find \displaystyle\lim_{x \to PM\infty}\dfrac{NUM.text()}{DEN.text()}.

0

* fractionReduce( NUM.getCoefAndDegreeForTerm(0).coef, DEN.getCoefAndDegreeForTerm(0).coef )
* fractionReduce( -NUM.getCoefAndDegreeForTerm(0).coef, DEN.getCoefAndDegreeForTerm(0).coef )
* +\infty
* -\infty
* undefined
"
