@Arsalan06 I am also confused by this. For question 5, I applied that same logic and wrote /A , since it says none of the tech advances, and negated the second claim (/App) and was left with /A---> /App. Once i read it out loud, "if (some?) recent tech advances, then it (tech advances) can be applied to producing power at traditional plants.

However, the claim is saying that NONE of them (which I'm assuming removes the inclusive component that could imply some tech advances are present). So, it's an incorrect translation. Perhaps I'm focusing on the "technicality" of the translation a bit too much, but it's intentional—I want to avoid using my intuition and learn how to apply the translations in a way that will help me save time.

I would really appreciate some feedback! I feel like I'm overcomplicating this, but I want to avoid missing a detail that could hinder my progress.
