Without knowing the central idea from question number three, it's difficult to accurately select the two details that support it. However, based on the sentences you've provided, it seems like the central idea might be related to Vivian's excitement and positive feelings about her new environment. If that is the case, the following two details from the story support this central idea:
"Her dad wasn’t particularly excited about the bubble-gum-colored entrance, but Vivian was thrilled."
"She was delighted to smell the delicious aromas floating in the air."
Both of these sentences highlight Vivian's excitement and positive reaction to her new surroundings, supporting the central idea of her feeling happy and thrilled about the new experiences she is having.
