I just did a 16 question LR drill, ulimited time. I can tell how well I managed time for each question but not for the 16 question cohort. If I'm doing a set of level 4 questions, then it's particularly useful to know how I managed my time in aggregate, rather than just for each question, since questions will inevitably vary regarding how much time it takes to answer correctly, and what's really important is the big picture view of tme management -- not just per question. I can calculate this myself by adding/subtracting results for each question in the cohort but you guys should do that automatically for me, please.
I appreciate the other responses here, but your question is really about how to deal with two conditional indicators in one sentence. I think you have to start with translating "unless", even though with two conditional indicators present, "cannot" and "unless", you'd think you can start with either; here's why: consider this simple group 4 indicator statement:
Students cannot attend the prom if they are under 18.
Cannot is a group 4 indicator so:
Negate either idea and make it the necessary condition:
If under 18, then must not attend the prom. Or is contrapositive:
If attend the prom, then must be not under 18.
But now consider an exact analogy to your question:
Students cannot attend the prom unless they are 18 or older.
You’re right; there is a group 4 and group 3 indicator in the stem. But I can only see one way to proceed – address the “unless’ indicator first, or you can’t wind up with a conditional statement. So:
Negate sufficient to get:
If not 18 or older, then must not attend the problem. Or its contrapositive:
If attend the prom, then must be 18 or older.
If you try to solve this statement by addressing "cannot" first, it can't be done, I think, because the sentence's structure won't support it as long as "unless" is present.
