Most hospitals have treatment options for cancer patients. All hospitals are able to treat all kinds of burn victims as well as all kinds of Neurology disorders. Ttherefore, there must be some hospitals that treat both cancer and burn victims and some hospitals that treat both cancer and Neurology disorders.
The pattern of flawed reasoning in which the argument 'All insects have an exoskeleton as well as a body that's composed of three parts: a head, thorax, and abdomen. Most insects are helpful to humans. Therefore, there must be some insects that are both helpful to humans and have an exoskeleton and some insects that are helpful to humans and have a head, thorax, and abdomen' is most parallel to that in the argument above.
