Rape question on Texas high school assignment prompts investigation, 'corrective action'

"Suzy was assaulted in an alley and is a victim of rape. The police obtained a sample of sperm. ... Which of the suspects raped Suzy?"

A Texas school district said it has taken "corrective action" after a ninth-grade biology teacher included a question about rape on a homework assignment.

The Klein Independent School District said in a statement that "the inappropriate homework question" was given to freshman biology students at Klein Collins High School in Klein, a suburb of Houston.

A photo of the question was posted on Facebook by a woman whose neighbor is the parent of a child who received the assignment last week. The photo was widely circulated online and provided to NBC News.

The question read: "Suzy was assaulted in an alley and is a victim of rape. The police collected a sample of sperm that was left at the crime scene and now have three suspects in custody. Which of the suspects raped Suzy?"

The answer choices were listed as "felon, S1, S2 or S3."

The school district said the assignment is not part of its approved curriculum and "is by no means representative" of the district's instructional philosophy.

"The district has investigated the source of the materials and appropriate corrective action has been taken," the statement said.
