Thanks for posting,

First, you are correct that this is a flaw question, and as a result we do break down the argument core the same way that we break down all assumption family questions!
But the language cues but/however/yet do not always indicate a conclusion! Take a look at the following two arguments:
Joe thinks pizza is horrible. But pizza has cheese!! So, pizza is actually awesome.
Joe thinks pizza is horrible. But pizza is actually awesome, because it has cheese.
What's the difference between these two arguments? In both situations, the "but" simply separates Joe (the opposing point) from my argument. Also, both arguments have the same conclusion (that pizza is awesome), based on the same premise (pizza has cheese). The difference is the order that the premise and conclusion come in AFTER we get past the "but"! In the first argument, the keyword "so" points to the conclusion; the in second argument, the word "because" introduces the premise.
Words like 'but', 'however', 'yet' indicate a
contrast, but they don't necessarily tell me anything about premise vs conclusion. They will often separate the opposing point from the author's argument as a whole, though! In this argument, the 'but' simply indicates that the first sentence is the opposing point. The 'so' at the beginning of the final sentence signals that it is the conclusion!
Be careful not to confuse contrast words with conclusion indicators!
Please let me know if this helps clear things up a bit!
