Question 47 - 49 refer to following paragraph:

W: Marcus, have you finished designing the layout for our new online clothing store? (47) I’m really excited to start selling our clothes online as well as the first offline store. Can I see the website?
M: Sure, but there are still a few changes I would like to make. I’m worried that some customers might get confused while navigating the website. (48) I think I need to simplify the interface more. What do you think?
W: Actually, I like it the way it is. I don’t think it’s too confusing. (49) However I think we need to add more photographs of the products. If customers can’t see exactly how the products look, they might be discouraged from making a purchase online.
