Although the code of the Nutri-Fare Grocery Store states that the company must employ some workers with disabilities, no blind or deaf employees have yet been hired for employment by the grocery store. Ttherefore, the grocery store is currently in violation of its code. The conclusion of the argument follows logically if which one of the following is assumed? ['The grocery store currently has no employees who are blind or deaf.', 'All employees of Nutri-Fare live within five miles of the store.', 'All employees with disabilities are blind or deaf.', "The grocery store's code cannot be modified in order to avoid its being violated."]
