For Reason 1, the best fitting sentence is:
"Younger generations will benefit from no student debt."
In this context, you should select "Young people can begin saving for retirement or large purchases much earlier in life." as the corresponding Evidence 1 for Reason 1.
You would then use "Response area" for Evidence 2 to provide additional support related to the benefits of being free from student debt, such as:
"With less financial burden, young adults can invest in their future more effectively."
