This is an Errors in Reasoning question. You're given some help here, because Lana actually articulates the error in Chinh's reasoning for you.
Chinh is comparing apples to oranges — museum paintings to television producers. This is a faulty analogy--a flawed method of reasoning. You cannot compare two fundamentally different things and then draw conclusions based on that faulty comparison.
This is exactly what Lana points out — that television, unlike museums, is *expressly* for the viewing public (by contrast, museums exist not only to make art available to the viewing public, but to preserve and restore art for the future, for research and study, etc. etc.). She explains that a TV producer is more like a CEO — in other words, she uses a more appropriate analogy to undermine Chinh's argument.
Answer choice (E) expresses the flaw in Chinh's argument according to Lana — Chinh has relied on a faulty analogy.
Answer choice (D) is a trap. Notice that Lana does NOT talk about museum-goers at all. She's not saying that NO painter EVER considers the museum-going public. She's just saying that television is EXPRESSLY for the viewing public. This is why answer choice (D) is wrong.
Hope this helps! Please let us know if you have any additional questions.
