Can someone explain this without using conditional logic arrows? I was stuck between a and d but d is an incorrect reversal

Hi everyone,

We could explain this without conditional logic arrows, but they actually make this problem a lot easier to understand.

Here, our premise is that computer voice-recognition can't distinguish between homophones (A).
We conclude that if computer voice-recognition can't recognize and use grammatical and semantic relationships, then it can't accurately translate spoken words into text (B - >C).

Thus, what are we assuming? In order to get from A to B - > C, we need B - > A, and A - > C.

Now take a look at (A). (A) states that if it can distinguish between homophones, it can recognize and use grammatical and semantic relationships. In order words, this tells us if not A, then not B. This is the contrapositive of one of the assumptions we need. Hope this helps.
