Which of the following statements is a claim of definition? a. any sport in which athletes purposely collide with each other is considered a full-contact sport. b. full-contact sports are bad because they cause some children to have low self-esteem. c. responsible parents should not allow young children to play full-contact sports. d. the leading cause of concussions in children is full-contact sports.

A. It refers to the definition of full-contact sports, where the condition is that the sport must have athletes must "purposely collide with each other" to be able to fit into that definition and category of full-contact sport.

B, C, and D are not definition statements. B is an opinion, since it claims that full-contact sports are "bad", which may be subjective from person to person. C is also an opinion, because parents "should not" allow children, tapping on parents instinct to feel "responsible". D is a statement of fact/statistic.

Hope this helps! :)

Is there any answer choices? : )
