Homeowners who commute more than 60 minutes to work each day spend, on average, 200 minutes less time each month doing outdoor chores than homeowners who commute less than 60 minutes each day. Despite what one would expect, studies show that the yards of the two groups of homeowners do not differ extensively with respect to the number of planted trees, the length of the grass, or the number of weeds. Which one of the following, if true, most helps to resolve the apparent discrepancy in the information above? ['Homeowners who commute more than 60 minutes to work each day spend 300 fewer minutes on all household chores than homeowners who commute less than 60 minutes to work each day.', 'Homeowners who commute more than 60 minutes to work each day have 40 percent smaller yards than homeowners who commute less than 60 minutes to work each day.', 'Homeowners who commute more than 60 minutes to work each day are less likely to invest in the more advanced gardening tools.', 'Homeowners who commute more than 60 minutes to work each day tend to do more inside chores than homeowners who commute less than 60 minutes to work each day.']
