A school in the United States has been slammed after given students homework with a sexually explicit question about "revenge sex" and "baby daddies".
Omar Austin, from Florida, was outraged after reading the homework that his daughter's Year 11 science class was given.
The question read:
"Ursula was devastated when her boyfriend broke up with her after having sex.
To get revenge, she had sex with his best friend the next day. Ursula had a beautiful baby girl nine months later.
Ursula has type O blood, her ex-boyfriend has AB blood and his best friend is type A blood.
If her baby daddy is her ex-boyfriend what could the possible blood type(s) of her baby NOT be?"
Mr Austin posted a video of the homework on Facebook, which has already received over 40,000 views, with the caption: "This needs to be seen. WTH is going on in our schools?"
