Question

how do the subheadings under \after high school\ contribute to the organization of \career planning for high schoolers.\?
by informing readers of the education options being described
by defining key terms essential to college applications
by providing links to supplemental sources of information
by sharing students insights about life after graduation

Explanation:

The text is about career planning for high schoolers, and the "After High School" subheadings would logically organize content by outlining the different post-secondary education paths available to readers, which aligns with structuring the guide's organization. The other options are not focused on organizational structure via subheadings: defining terms is a content detail, links are supplementary resources, and student insights are anecdotal content rather than organizational tools.

Answer:

by informing readers of the education options being described
