Conditional Possibilites vs Certainties Drill 2-59 #4

[rameday]

Hello,

SO I am a bit confused about Question 4

If H does not occur

I understand why P or Q occur but I am not sure why it is MBT that both P & Q occurs. I didn't realize that in conditional reasoning with the OR construction it is MBT that both occur as well as one or the other occur.

For could be true I understood why N does not occur and N occurs are the answer but I am not 100% sure as to how they got to the other answers.

For cannot be true I incorrectly wrote that both P & Q occur cannot be true. I did accurately write though that both P & Q not occur cannot be true though.

If Q occurs, I got all the 6 could be trues correctly. What I got wrong was in MBT I put P occurs and P doesn't occur. For CBT I put Q not occurring (although in retrospect that is self evident)

I would appreciate some explanation

I just wanted to add that initially when I did this drill for the life of me I could not make sense of it. However, now after listening to all the virtual modules from lesson 1 and 2 this drill makes a ton of sense for me. Aside from the confusion I had with question 4 I got every single correct and quite easily and intuitively. I was super nervous to do this drill because I remembered how much trouble i had with it initially but I was excited to see how easy the majority of the answers came to me once I started.

Woot for understanding!

This leads me to another question, how important is knowing the certainties and possibilities for conditional statements on the LSAT and also how does this type of drill apply to questions?

Dear remedy:

No, it is not must-be-true that both P and Q occur, only that at least one of them occurs.
Thus, for could-be-true, one may have P, or Q, or both, as the answers say.
If Q occurs, how could you know whether P occurs or not? How are they connected?

Hope this helps,
David

Dear rameday:

Glad the modules helped!
As for your question, am not sure exactly what you mean. Obviously, it is very important that you know the difference between must-be-true (and its form "cannot-be-false"), could-be-true, etc. If you don't have that down thoroughly, you are probably in big trouble come test time.
Also, the drill tests you on things which can be easily applied to questions. The parameters of certainty, possibility, etc., are ubiquitously tested not only in logical reasoning and logic games, but maybe even in reading comprehension at times. So, do all the drills you reasonably can!

Hope this helps,
David

Wait I am a bit confused. In the back of my book it says that If O occurs it is MBT that P or Q or both occurs.

Hello,

Yes, one or both occurs. But above, you say that "I am not sure why it is MBT that both P & Q occurs", which is not correct.
