I think that it is pretty clear what the expected answers are. And most of them can be narrowed down, without even reading the text, by looking at the conecting words "if," "than," and "who." [I use American punctuation with the commas and periods inside the quotes.] However, I'm wondering if the "who" clause after "rich parents" really is restrictive and thus may be joined without a comma, as the text seems to do.
My other observation is that this and "Vesuvius" really are cultural knowledge tests. Someone sent to Europe by rich parents will have seen Pompeii and will be able to comprehend the text a lot quicker. (Just as being a lawyer, I can look at an American or Russian court decision and understand it very quickly.)
Anyway you should visitNaples. As the Italians say, "Vedere Napoli e poi morire!"
