Hey stevo.uoeno,
Thanks for your post, and welcome to the forum!
I'll begin backwards by addressing your last question first. Indeed, "the only" is always immediately followed by a sufficient condition (unlike "only if," which introduces a necessary condition). For instance:
The only way to eat Oreos is to forget what's in them.
Eat Oreos Forget
(Contrapositive: Remember Don't eat Oreos)
The only people who never fail are those who never try.
Never fail Never try
(Contrapositive: Sometime try Sometime fail)
So, the statement "The only alternative is subsidy" means that if there is any alternative (to making money), it will require subsidy:
Alternative Subsidy
Now, let's think about this stimulus holistically. In the first two sentences, the author tells us that the press needs to make money to survive:
Survive Make money (i.e. profit-making)
In the third and fourth sentences, we learn that there is an alternative to making money: if the press were not profit-making, it would require subsidy. When the author says that "the only alternative is subsidy," you need to think about what this means in the context of the previous sentence: the only alternative to what? To making money, of course. In other words, if the press were NOT profit-making, it would need subsidy to survive:
NO profit-making Subsidy
If I recall the stimulus correctly, the author goes on to say that no one would subsidize honest journalism, meaning that if the press were to receive subsidies, it will not produce honest journalism:
NO profit-making Subsidy NO honest journalism
The contrapositive of this chain likely validates the correct answer choice:
Honest journalism NO subsidy Profit-making
Does this help? Let me know.
Thanks
