Teacher, I just finished my grammar and I think this unit is easy. But I got some thing that I know how to answer, but I don't really know the mean very well, like I do know the mean but I am not determine. Here is the question that I want to ask you. They want you to  click on the correct sentence ( the first sentence is She has the confidence when speaking in front of an audience. The second sentence is  She has confidence when speaking in front of an audience. So I don't understand the meaning. So I need you help with that.
