Dave,
Im having a hard time with question 22. I picked B, i still can't see why M or J should be included. Help me!
thank you,
Ale
If M doesn't see T, then she sees both S and U. (Rule 1)
If J doesn't see T, then she must see either S or U.
But M and J cannot see the same play! (Rule 2)
For 21. We know L,M,O are all watching Undulation. So we also know answer A,B,C aren't the correct ones because they can't be true. Then for D and E, can't we just quickly conclude it is E that could be true since L can only review one movie and is already reviewing Undulation? Is this method efficient or should I ALWAYS diagram the possibilities like you did?
Seems I ended up having more issues than I thought I would:
1. Also for rule 4) does "each other" imply they have to be NEXT to each other?
2. For 19, I assume they are talking about an accurate list within one diagram, not generally who can only watch S? Because I ended up choosing C (J,L)
1. It sounds as though you're suggesting stopping your work partway through to inspect answer choices. If so, I urge you not to. While there are certainly instances where a small bit of work is enough to reveal the answer, there are many more instances in which you have to complete the picture (i.e., Rule of Two that shit) in order to see the right answer. Alwasy doing the work is more efficient over the long haul.
2. No; there's no "next to" in this game. We've put them in alphabetical order, but that's just because in order to put them onto paper, they had to go in some order. The game doesn't give any order, so it cannot ask for any, either.
3. Broadly speaking (because you will see this again), the question is what’s the difference between a question that says:
1. “Which of the following is a complete and accurate list of all of the cars, any one of which could be parked in the third garage?”
and one that says:
2. “Which of the following could be a complete and accurate list of the cars parked in the third garage?”
Answer:
Question 1 above asks for a global accounting of all of the cars that could ever park in the third garage.
Question 2 asks you for a single possible scenario - of all the possible combinations of cars, Question 2 just wants one such possibility.
You can quickly and accurately assess the different demands posed by these two questions by tracking the position of the word “could” within the sentence:
If the word “could” is near the end of the sentence (as in Question 1), then you’re looking for an answer giving a complete list of all possible entities.
If the word “could” is near the front of the sentence (as in Question 2), then you want a snapshot - an answer choice that gives you one possible permutation of elements to spaces.
To recap:
If could is near the end, then you want a global account.
If could is near the beginning, then you want a single permutation.
Hi Dave, Q22: If L and M do not see the same as J, then why would I not choose C as an option? Is it not possible for K, O, M and L to see T? If so, C/D would be flips of each other and I don't get how I would rule one out over the other. Please help. Thanks
Never mind, I drew it out again and figured it out. Thank you :)
Quick question about the statement "but do not review any other plays". Am I missing the significance of that statement in the question, or is it ok to assume that was a dismissable statement since they only provide 3 possible plays?
Is there ever an instance where a number of options are stated, and an additional unnamed element is a variable that might make that particular statement relevant? I'm trying to train myself to include or ignore relevant information but don't want to make an incorrect assiciation that when we see only 3 options and it states there are only 3 that's pretty much obvious and we can ignore it.
Yeah, you're right to ignore it.
In a trivial sense, it's real information; it allows you to be certain that the three plays mentioned are the only ones you need to worry about.
But if you know who the elements are, how you're going to arrange them, how many spaces there are to fit elements in, then you've got what you need.
Let me know if I can help!
