Question

which detail supports the inference that the first day of school could be dangerous for ruby? the marshals were greeted by ruby when they came to her house that morning. ruby’s mother thought that people from the naacp were knocking at the door. the marshals said they would surround ruby as she walked into the school. ruby’s mother took special care getting her ready for school before the marshals came.

Explanation:

The question asks for a detail supporting that Ruby's first day of school was dangerous. Having marshals surround her implies a need for protection, which directly indicates a potential threat or danger. The other options do not signal danger: greeting marshals is a friendly act, mistaking knockers for NAACP is a misidentification, and special care getting ready is just preparation without a clear link to danger.

Answer:

The marshals said they would surround Ruby as she walked into the school.
