The number of antelope in a certain herd increases every year at a constant rate. If there are 500 antelope in the herd today, how many years will it take for the number of antelope to double?
(1) Ten years from now, there will be more than ten times the current number of antelope in the herd.
(2) If the herd were to grow in number at twice its current rate, there would be 980 antelope in the group in two years.

In my opinion you shouldn't even waste time with this one.
1. Is obviously not calculatable since "there will be more than ten times the current number" could easily mean 12 times or 13 times, but not a fixed number so //insuff (my thoughts I could be very wrong here)
2. Obviously calculatable so I would go with B on this one right after I read it (20 sec).
Then again, I could be wrong.
Other opinions are very welcome.
