Answer: She appreciates his sign.
Explanation: The correct answer is 1. She appreciates his sign. The passage describes that Skyler saw the image of her brother on the giant TV screen and saw his sign, "Skyler Jameson - Big East Player of the Year!!" Then, it says that she looked up and found her brother, and gave him a special smile. This special smile is most likely a gesture of appreciation for the sign that Jordan made for her, as it shows his support and admiration for her accomplishments. The other options, such as her being nervous, surprised, or wanting him to stop hiding, are not explicitly mentioned in the passage and are less likely to be the message she is trying to send.
