Ms. Sue could you please have a moment to look at my other previous question, the one I was having trouble on, thanks
Those answers are fine. :-)
Even this one: These differences were important because with these differences the NWC could learn benefitting things from the HBC and the HBC could do the same with the NWC.
It doesn't really look right.
You're right. It would be better if you wrote:
These differences were important because both the NWC and the HBC benefitted by learning things from each other.
