This question stem gives us the could be true except wording. When we go to this paragraph, do we see any conditional logic this time? Yes, we actually see quite a bit, only when, until essential if, yes, those are all conditional logic trigger words. It's about 15 or 20 words we should memorize that show up a lot to introduce conditional logic, and we want to memorize for each word whether it introduces a sufficient condition that we would put on the left side of the arrow, whether it introduces a necessary condition that we would put on the right side of the arrow, or whether it's one of those special, if not words like unless, that we saw in the previous problem. The most common sufficient triggers are things like if, when, where, whenever, wherever, any universal, like all each, any, every. And the only is a sneaky little counter example, because only an only if, and only when, are the most common necessary trigger words.
