Ravi: The highest priority should be given to the needs of the sales department because without successful sales the company as a whole would fail

Ed: There are several departments other than sales that must also function successfully for the company to succeed. It is impossible to give the highest priority to all of them

Ed criticizes Ravi's argument by pointing out:

a. That the sales department taken by itself is not critical to the company's success as a whole
b. The ambiguity of the term "highest priority"
c. That the departments other than sales are more vital to the company's success
d. An absurd consequence of its apparent assumption that a departments' necessity earns it the highest priority
e. That Ravi makes a generalization from an atypical case
