Editorial

Last year in Metron County, more than 75 percent of all school cafeterias, large and small, consistently received the county health department's “excellent" rating for cleanliness, the highest rating possible.Thus,although 75 percent is far from perfection, at least we know that over three-quarters of the lunches served to children in Metron County school cafeterias were served in conditions of cleanliness that the health authorities rated as “excellent."

The conclusion of the argument is properly drawn if which of the following is assumed?

A.Metron County's health department rates school cafeterias not only on their cleanliness but also on the overall nutritional quality of the meals they serve.
B.Every year for the past five years,whenever a school cafeteria in Metron County received a rating of "excellent" for cleanliness, the proportion of students in that school who regularly ate in the cafeteria increased sharply.
C.Last year Metron County imposed strict sanctions to ensure that cafeterias receiving less than an “excellent" rating took measures to increase cleanliness.
D.Last year,those school cafeterias in Metron County that did not receive an “excellent" rating served fewer lunches, on average, than did school cafeterias in Metron County as a whole.
E.In those Metron County schools that do not serve lunches to students, any areas in which students regularly eat lunches are rated for cleanliness by the county health department.
