I had the answer laid out properly and concluded something completely different! I don't understand the explanation...

Hi @Zikica,
Thanks for the question! So we can diagram this one, so let’s do that! We’ll start with the first sentence:
Economy weak —> Prices remain constant & Unemployment rises
Now for the second sentence:
Unemployment rises —> Investment decreases
And now onto the last sentence:
~Investment decreases
So this is a fact pattern in which we’re just given three premises, and we have to find something that must be false based on them. Can we combine them at all? Yes, we can. Take the contrapositive of two.
~Investment decreases —> ~Unemployment rises
And then the contrapositive of one.
~Unemployment rises v ~prices remain constant —> ~Economy weak
And now we can link these all together!
~Investment decreases —> ~Unemployment rises —> ~Economy weak
And so remember: this is a MUST BE FALSE question. Can it be true that either the economy is weak or investment is decreasing? No. We know that investment isn’t decreasing. And we know, based on our conditional, that this means the economy isn’t weak. So (A) can’t be true and is the correct answer.
Hope this helps! Feel free to ask any other questions that you might have.
