I agree.

To determine which of the following details supports the main idea that Pa worked hard to try to feed his family, we need to analyze each option and see how it relates to Pa's efforts to provide for his family.

A. "Pa and I walked, because I was a big boy of eleven."
This detail indicates that Pa and the narrator had to walk instead of using some other means of transportation. While it suggests that Pa was taking an active role in ensuring their movement, it does not directly support the idea of him working hard to feed his family.

B. "Were prid near out of grub my father told her."
This detail implies that Pa informed someone that they were running out of food. It suggests that Pa was aware of the scarce resources and was actively communicating about this issue. Though it indicates the difficulty they were facing, it does not specifically highlight Pa's efforts to work hard to feed his family.

C. "He traveled twice as far each day as the wagon."
This detail highlights how Pa's efforts surpassed the capabilities of the wagon. By traveling twice as far, Pa is demonstrating his determination and commitment to obtaining food for his family. Therefore, this detail directly supports the main idea that Pa worked hard to feed his family.

D. "He glanced at us anxiously as he tore at the ropes that bound the pack."
This sentence suggests that Pa was in a hurry and trying to free something from being bound by ropes. While it indicates some urgency, it does not explicitly support the idea that Pa was working hard to feed his family.

Based on the analysis, option C, "He traveled twice as far each day as the wagon," is the detail that supports the main idea that Pa worked hard to try to feed his family.
