Three reporters were discussing the hockey results. The TV reporter said "Either Brazil won gold, or Chile won silver, but not both." The radio reporter similarly started to say "Either Argentine won silver, or Chile won …", but a sudden noise cut him off.
The press reporter, who was lucky enough to hear the complete sentence, could reason out the final order of the three countries. What was it?

I agree with the solution. As to the "but not both", I included it to make sure that "Either A or B" was understood as ("A and not B" or "not A and B").
For me, the "but not both" was unnecessary, but in at least one of Smullyan's books, he used the "either/or" construction meaning "A or B"...
As it was correctly noticed, the "similarly" implied that the second reporter would have ended his sentence with "but not both".
