I was confused with question stem. It took me a while to understand whether it is assumption question or inference question
In the United States, the Postal Service has a monopoly on first-class mail, but much of what is sent first class could be transmitted electronically. Electronic transmittal operators argue that if the Postal Service were to offer electronic transmission, it would have an unfair advantage, since its electronic transmission service could be subsidized from the profits of the monopoly.
Which of the following questions can be answered on the basis of the information in the passage above?
(A) Is the Postal Service as efficient as privately owned electric transmission services?
Can it be Yes or NO?
answer: Don't know
(B) If private operators were allowed to operate first-class mail services, would they choose to do so?
Answer- maybe, maybe NO
(C) Do the electronic transmittal operators believe that the Postal Service makes a profit on first-class mail?
Oh Yes! that's why operators saud that they would have an unfair advantage because of profits from first class mail
if the Postal Service were to offer electronic transmission, it would have an unfair advantage, since its electronic transmission service could be subsidized from the profits of the monopoly.
(D) Is the Postal Service prohibited from offering electronic transmission services?
Answer= maybe but also possible they may not be interested or they may not have resources
(E) Is the Postal Service expected to have a monopoly on electronic transmission?
answer= why monopoly? monopoly on one business by one company not necessary to have a monopoly on other business. But it is also possible that in long term it would have monopoly? I am not sure
C is better option
