This is not supported. The stimulus says Baxe is “one of the largest” design companies, which implies that there are other very large design companies, but we know nothing about the quality of their designs.

This is not supported. Corporate interior design is the only category the stimulus discusses, so we just don’t know how Baxe’s market share compares in other categories.

This is not supported. We can infer that at least some small companies probably produce at least some designs better than those produced by Baxe, but we don’t know how many. This means we have no idea if it’s “most” or only a few.

This is not supported. All we know about corporate managers is that they only work with very large companies. It’s entirely possible that they know of better designs out there, but just care more about a company’s stability.

This is strongly supported. Because smaller companies have won awards and Baxe hasn’t, we can infer that there are some designs better than those produced by Baxe. We also know that corporate managers don’t work with smaller companies, thus leaving Baxe’s near monopoly safe.
