Question

what made the photo of the migrant mother so powerful? it made people feel sympathy for the migrants. it led the federal government to help the migrants. it revealed the terrible conditions migrants lived in. it made people aware of the dust bowl.

Explanation:

The "Migrant Mother" photo (by Dorothea Lange) was powerful because it revealed the terrible conditions migrants (specifically during the Dust Bowl and Great Depression) lived in. It depicted the hardship, poverty, and struggle of migrant workers, which was a key reason for its impact. The other options: making people feel sympathy is a result of revealing the conditions; leading the federal government to help was a later outcome; and making people aware of the Dust Bowl is related but the core power of the photo was showing the migrants' living conditions.

Answer:

It revealed the terrible conditions migrants lived in.
