One factor could be the sponsor is not an English speaker. Check out his/her snapshot page on their language preference. There are some who just do not know how to express themselves but do not get discouraged. You can contact your co-sponsor or anyone in your upline. I'm sure they would be willing to help.
On the other hand, there is much resources within SFI to draw from. Keep reading and learning. I like Forum as it is another avenue to ask questions.
