It is not necessarily true that the girls shows off her new spring dress for her mother, as she may or may not be showing off, she may or may not be wearing a new spring dress and she isn't necessarily showing off for her mother.


Consider the statement "A girl holds a teddy bear while wearing a floral outfit and pink shoes.". Based on this "The girl shows off her new spring dress for her mother." a true statement? Yes, no, or I don't know?
