Are there any multiple choices for this question? Since there isn't, I'll propose a few.
"Karen felt a great connection with nature when she went hiking."
"Karen felt a great attachment with nature when she went hiking."
"Karen felt a great understanding (of) nature when she went hiking."
And if this is a multiple choice question, please list the choices.
