Answer:
"It had been almost four weeks since she’d ridden Dark Star, and Giselle was adamant that her broken arm would not inhibit her riding."
Explanation:
This is the line from the text that shows that Giselle is so passionate about horses and riding that she sometimes is careless about her safety. In this line, we learn that Giselle really misses riding and cannot wait to ride Dark Star again. Therefore, she decides to go riding even though she has a broken arm. This can be very dangerous, and serves as evidence of how careless Giselle can be when it comes to her personal safety.
