Hi student!

First of all, thank you so much for re-writing the question in English! =) I appreciate you~

Second, you bring up a great question.

It does seem a little odd to pair a negative and postive word together; however, it is totally possible, though not very common.

For example

"the lovable idiot," "a spectacular failure," "a miserable smile," "the perfect murder"

You get it, right? =)

To reiterate, this positive-negative pairing isn't common, and the reason a writer does this if for effect (to get a reaction from the reader). If you were a bit surprised by the correct answer, the writer did his job. =)

However...

the more important point to take away from this question is that, for the SAT, the writer can choose a word to mean WHATEVER he wants; in some cases, the meaning will match the definition students are familiar with; in other cases, the definition will be based on the word's secondary meaning; in still other cases, the meaning of the word will be something else.

For these reasons, it is really important for you to consider the "context" (the surrounding infromation).

It seems like you understood that "disappointments referred to "southern trip" and "spring gown." Good job there.

Now, how does the writer describe the trip and gown? By using words such as "long-planned," which means "look forward to/anticipate" and "consolatory," which means "comforting."

Thus, the closest meaning to the word "luxury" has to be "(C).

Hope this explanation helps!

Keep moving forward!

You got this!
