Ambiguous Quiz Questions

Due to the simplicity of the course, as this is a introduction to Objective C and iOS, I feel these questions are often misleading and quite ambiguous.

The fill in the blank ones are especially. "What is the rectangle box that appears on the main.storyboard file?" Yes, it's a view, but more specifically, it's a root view controller that holds a particular view, allowing for UI controls to be formatted. "the ________ controller collects input from the user"? what type of fill in the blank is this? (these examples are not verbatim, as this popup form is taking over the page)

If these quizzes are here to help users gain a better understanding of Objective C, they should be structured quite differently. I am tired of missing simple questions that are merely written to vaguely to provide an answer that is exact as what it is being expected. At least offer a wider variety of questions, rather than reordering them and sending them back out.
