_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
In our second sentence, we see until, which is an if not.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So we need to put on the left side, if teachers do not have the power to make decisions in their own classrooms.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
The tricky thing here is that the other idea needs the knot that appeared earlier in the sentence.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We're saying if teachers don't have the power to make decisions in their own classroom, then they cannot enable their students to make their own decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
This was a weird phrasing where I could say, until you clean up your room, you cannot have dessert.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
But I also could have said, not until you clean up your room, can you have dessert?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
They would mean the same thing.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
The third sentence gives us the word essential, which is a synonym for necessity.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I would ask myself, all right, what's the required thing in this sentence?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If you're telling me that students' capability to make their own decisions is essential, it's required, then I know that idea goes on the right side of the arrow.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I need students are capable of making their own decisions on the right side, becoming an independent learner, then takes the left side.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We can read conditional statements as the left side requires the right side.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I can read this conditional as becoming an independent learner requires that they're able to make their own decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Lastly, the final sentence uses if the classic, the put it on the left side.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So if teachers are effective, then they must have the power to make classroom decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
One bizarre thing about this question stem is that it said we were going to be reading an argument and still being asked what must be false.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I wasn't sure if we would have to treat assumptions as though they are true.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
But before I even get there, I just want to figure out what's going on with all this conditional logic.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
When we get more than one conditional logic rule, they often link together.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So we want to look to see, do they have any repeating ideas?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Well, effective teachers showed up twice, becoming an independent learner showed up twice, having the power to make classroom decisions showed up twice, and being able for students to make their own decisions showed up twice.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Let's pull out that first rule.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If you're an effective teacher, you can help your student become an independent learner.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Can we chain anything onto that?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Sure.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We've a rule that says, if the students are becoming independent learners, then they must be able to make their own decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Can we chain anything onto that?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Well, I see a rule about students making their own decisions, but I would need to contrapose it to chain it on.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I will.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
I'll think, all right.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If students are able to make their own decisions, then the teachers did have power to make classroom decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Those first three ideas chained A to B, B to C, C to D.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So let's synthesize it and make this look a little bit easier.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If you're an effective teacher, can help your student become an independent learner, which means that students able to make his own decisions, which means that you, the teacher, clearly had the power to make classroom decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
When we look at our conclusion, we realize there's really not a new thought happening there.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
That was just a correctly derived conclusion.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Effective teacher implies power to make classroom decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I don't have to worry about whether or not there were assumptions that we should also be treating as true, because this argument was actually a valid argument.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
The conclusion just summarizes our conditional chain.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If we're going to find something that must be false, then we have a big old conditional chain, then we should again be reminding ourselves, that's going to sound like you are the trigger, which are not the outcome.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
But the question stem was actually even more specific.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
It said, what would we know about teachers who have enabled students to make their own decisions?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So that's our third link.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
And when that is true, it tells us that fourth idea.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We know that if the students are able to make their own decisions, these teachers apparently have the power to make classroom decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So we can infer these teachers definitely have power to make their own classroom decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
But we can't go backwards in a conditional chain.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So I have no idea whether they're effective.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
I have no idea whether they are helping their students become independent learners.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
When we look at the answers, we can see that D is actually giving us that inference.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
That must be true.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
They definitely have the power to make decisions.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So D is wrong.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We're looking for something that must be false, and D must be true.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
A, B, and C are dealing with those unknowns.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We don't have the ability to go backwards.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So we have no idea whether or not they're effective.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We have no idea whether or not they're helping their students become independent learners.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
E mean while contradicts the inference we were able to make.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We know they have the power to make decisions in their classroom.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So E is contradicting that.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So no, they don't.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
They don't have the power.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So E is our correct answer.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
D was something that must be true.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
That actually was the available inference.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
A, B, and C were just toss-ups.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
They could go either way.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We have no idea.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
All right.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
So once again, how do we spot must-be-false questions?
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
It might say must-be-false.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
It might say cannot be true.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Could be true except least compatible or violates a principle.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
The most common reasoning structure by far will be conditional logic.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Most correct answers will either contradict a conditional rule or they'll contradict some available inference that we could have made by combining ideas.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
When it comes to trap answers, you could lump them all together and just say, well, they all could be true.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
But when we think about how the test writers design them, we could get a little bit more granular.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Some things are unopposed meaning they certainly fit within the information we were given.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If I say that somebody uses a wet nap after they eat shrimp, it's certainly unopposed to say they also use it before they eat the shrimp.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Out of scope is really referring to bringing up brand new things we'd ever talked about.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Bringing up a brand new thing means that there's no possible way we could contradict it because we didn't even get any information about it in the first place.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Supported is more like an answer that is a valid inference or sounds like it pretty reasonably goes along with the paragraph.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
We're looking for something that starkly goes against the paragraph.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Reversal negation refer to ideas that are tempting because we know it's an incorrect manipulation of a conditional logic rule.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
It's not a valid inference.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
But it's not that's not the same thing as contradicting a rule.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
Finally, some answers will be too weak to contradict, which is sort of like saying unopposed that they could still fit within the margins of the facts we were told.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
If I'm told that most clowns are scary and an answer says some clowns are really nice and welcoming, that doesn't contradict.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
It's too weak.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
There's room for some clowns to be nice when I've only said most clowns are scary.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
All right, thanks a lot for learning with us.
_9fM5XUMpYg
"2021-07-06 13:00:03 UTC"
Must be False
