pros and cons:
the bear (when standing) could take out the lion easily by shear weight, strength and power. But he would be slow to stand, and in the time it would take for him to rise, the lion could easily make a fatal attack. But the bear has the ability to climb trees and escape if it were to see the lion coming, then attack from the tree. But i do belive that lions have the ability to also climb trees, if not too high... what is your opinion?

I am unclear about something, if you are one of these people lecturing posters about doing their own homework what exactly are you trying to accomplish? If asking math questions on yahoo answers offends you, then don't you have something else better to do then pontificate from your soap box about homework ethics? Is asking a question here somehow different then asking a professor during office hours? If so please demonstrate to me how. To sum up my little speech, if you have nothing constructive (pertaining to the current problem) to say please don't post. Just save it for your children or something.
