The following paragraph is taken from a textbook's discussion of children who have physical disabilities:
Physical and health impairments are general physical or medical conditions (usually long-term) that interfere with school performance to such an extent that special instruction, curricular materials, equipment, or facilities are necessary. Students in this category may have limited energy and strength, reduced mental alertness, or little muscle control. Examples of specific conditions that may qualify students for special services include traumatic brain injury, spinal cord injury, cerebral palsy, muscular dystrophy, epilepsy, cystic fibrosis, asthma, heart problems, arthritis, cancer, and AIDS. The majority of students with physical and health impairments attend general education classrooms for part or all of the school day (U.S. Dept. of Education, 1996). Which sentence within the paragraph most clearly shows APA style? a. The first sentence b. The second sentence c. The third sentence d. The last sentence
