danger for pioneers because they could
get dehydrated in the heat, or freeze in
the cold.

Explanation:

The text describes pioneers as people who settled the western territory of the US. They made plans, packed supplies, traveled in groups (caravans), and faced various challenges like weather. The options on the right are about who pioneers were. The first option refers to the first settlers in North America (not specific to US west - could be earlier like Pilgrims). The third option refers to Native American tribes (not the settlers). The second option “people who traveled west to settle the frontier” matches the description of pioneers in the text.

Answer:

people who traveled west to settle the frontier.
