When school opened in Texas this fall, some favorites were missing from the cafeteria menus. Soda; and ghouls op-when rand`, bars had been banned for grade schoolers, chips and cookies were mini•size. And that perennial favorite, the French fry, was given just one more year before it too will be banned. Howls of protest could be heard everywhere. Principals complained about being forced to act as “nutrition police.” Parents and kids traded schoolyard rumors about twinkles being confiscated from lunch boxes. Nearly everyone, addicted to the revenues that vending machines bring in, yelled that there wouldn’t be enough money for activities like band camp and choir trips. Angry e-mails poured in to the woman who had imposed the new rules-Texas agriculture commissioner Susan Combs. It is stated in the passage that both the students and the principals of the schools in Texas

a) Have the most qualified teaching staff

b) Are to commute between the campus and downtown

c) Intend to devise new methods of dieting

d) Seem to be displeased with the current food policy
