University budget committee: Athletes experience fewer injuries on artificial-turf athletic fields than on natural-grass fields. Additionally, natural-grass fields are more expensive to maintain than fields made of artificial turf. Nevertheless, this committee recommends replacing the university' s current artificial-turf field with a natural-grass field. Which one of the following, if true, most helps to resolve the apparent discrepancy in the committee's position? ["The university's current artificial-turf athletic field has required extensive maintenance since its original installation.", 'Maintaining artificial-turf fields involves the occasional replacement of damaged sections of turf, whereas natural-grass fields require daily watering and periodic fertilization.', 'Most injuries sustained on artificial-turf fields take longer to heal and require more expensive physical therapy than do injuries sustained on natural-grass fields.', 'Athletes who have spent most of their playing time on natural-grass fields generally prefer not to play on artificial-turf fields.']
