这是文章的结论，可以看出的就是CABLE公司认为TELEPHONE会去提供CABLE SERVICE因为-->他们可以获得利润。

问的是上面的信息可以回答下面哪个问题,那就要牵涉到利润才可以。

(C) Do the cable companies believe that the local phone companies make a profit on phone service?

CABLE认为TELEPHONE可以获得利润否?

文章中的信息回答了,是的CABLE认为TELEPHONE会去提供CABLE因为他可以获得利润。

E,文章只是提到利润，没有提到垄断，文章涉及的垄断是EVIDENCE,不是结论。TELEPHONE在CABLE上垄断不垄断没关系，文章的结论是,只要TELEPHONE能在这CABLE SERVICE上获得利润，他们就会去做。
