What’s the main difference between pseudo sufficient assumption vs. principle?
Is it just that PSA is a weaker (not logically airtight) version of a SA question, and that principle questions will always invoke some kind of moral action/ ethics doctrine to mimic? #help
Yes, you are correct. Also, principle questions will ask you to apply a principle from the stimulus to the answer choice (prove down), whereas pseudo sufficient assumption questions ask you to identify a principle in the answer choice and apply it to the stimulus (prove up). Hope this helps!
I must remember that for stems like #2, "Which one of the following is an assumption made by the argument?", the word "is" means to find the NECESSARY ASSUMPTION.
A Must Be True (MBT) question asks you to identify a statement that is guaranteed to be true based on the information provided in the argument or passage. You need to select the answer that must logically follow from the facts, premises, or details given in the stimulus.
Key Point: The correct answer must be supported by the premises in the stimulus. There cannot be any assumptions or guesses; it should be something that is always true based on what’s given.
When we are looking for a necessary assumption, we are looking for the assumption that already exists in the argument. By asking us to find the already present assumption, the argument is not asking us to come up with a sufficient assumption. It wants us to find the assumption the argument is already making. A sufficient assumption will force the conclusion to occur, but it does not necessarily have to be true.
Notice how "is most supportedby..." is in the passive voice. The direction is from the stimulus to the inference (the A/C) we can best draw from it. The inference doesn't do the heavy lifting on the stimulus here, but it's because of something or many things the stimulus said that we're able to reasonably add one more thing that wasn't stated before.
STRENGTHEN:
"Adds most support for" is in the active voice. That means that whatever the correct A/C turns out to be, it is intended to do the heavy lifting, and the flow is from the correct A/C (the strengthener) back up to the stimulus. In other words we are "actively" inserting whatever the correct strengthening premise is to bolster the argument we have been given.
Does this distinction make better sense?
Btw, it may be a little hazy now, but your understanding of how these Q stems (and their various other "masks") differ will sharpen as you encounter more of them.
Sufficient assumption is an assumption/element/piece of info that would enable the argument conclusion validly follow. In other words, there is a ‘gap’ in the argument and a SA functions to fill that gap so that the argument will be valid.
For example:
Freedom of speech is important, therefore it’s a right.
There is a gap in this simple argument which is: it’s ‘assuming’ if something is important, then it’s a right.
A correct SA could be worded in various ways one of which could be:
“Anything that’s important is a right.”
Now if we plug this back into the argument the conclusion will be valid;
“Freedom of speech is important, and anything that’s important is a right. Therefore, freedom of speech is a right.”
Now contrasts this to a MBT.
A MBT is an inference that validly followsfrom the argument, meaning there isn’t necessarily a gap and a MBT doesn’t have to ‘enable’ the validity of the conclusion but follows/inferred from the given info in the argument, be it an implicit inference we push out or else an explicit restatement of a part of the stimulus.
For instance:
Freedom of speech is important, yet ‘shouting out fire’ in public with no legit reason isn’t considered important.
That’s it. You see, we might not even have an argument in a conventional P/C sense but there is an inference we could deduce from the given info that’s MBT, which is: “shouting out fire in public without a legit ground is not considered as a form of freedom of speech.”
In lawgic you could see it as:
A → B, then the argument tells us something that’s B, what can we infer/conclude/MBT? —A.
Sufficient Assumptions would be:
A, therefore B
What’s the gap? — if A, then B (A → B).
The arguments could get way more complex and nuanced than this in terms of the structure, details and language but the difference in framework remains.
Sufficient assumption questions ask you to choose a premise that would guarantee the passage's conclusion. MBT questions ask you to choose a statement that must be true based on the premises of the passage.
From what I understand, most strongly supported answers are the ones that are most likely to be true based on the information provided in the stimulus. They aren’t guaranteed but are strongly backed by the details in the passage.
On the other hand, pseudo-sufficient assumptions are ones that might seem like they support the argument, but they don't actually ensure the argument's conclusion. They look like they do the job but aren’t truly necessary or sufficient on their own.
@thr107 Honestly if you came this far in the Logical reasoning module and still don't know how this helps that is a red flag. By being able to quickly identify what type of question you are about to answer you can apply the methods we learned in core curriculum as well as just know what to look for, which in turn will save you so much time on the LSAT, time being one of the most important factors. Good luck.
@thr107 There is an entire curriculum devoted to teaching you how to answer these types of questions. If the creators find value in identifying question stems, then I am sure this is worth our time. If you think I was talking down on you, you must agree that you were also talking down on 7sage. Good luck, I'm sure you're fun to be around!
To 7Sage Administrators: I just wanted to point out a spelling error in one of the answers of the questions above, #34 listed the answer as Main Point/Concusion when it should be Main Point/Conclusion. I know it's just a spelling mistake but I just wanted to bring this to your attention. #help
The PSA questions tend to ask about a principle that would justify the argument. There might be PSA questions that do not adhere to this rule, but I don't think SA questions ever have the word 'principle' in them.
I think it's important to note that SA questions ask for 100% validity, while PSA questions are not looking for the 100%, but rather something that's stronger than a strengthening but slightly weaker than a SA AC. It might therefore be useful to distinguish between these questions so as to not get confused looking for a perfectly valid AC in a PSA question for instance.

I made a quizlet of some of the question stems: https://quizlet.com/_6tjq9l
always someone thank you :D
I plan on doing all of these LR question stem quizzes over and over again. They are so helpful for reinforcement.

Sufficient assumption questions ask you to choose a premise that would guarantee the passage's conclusion. MBT questions ask you to choose a statement that must be true based on the premises of the passage.
Can someone clarify the differences between most strongly supported and pseudo sufficient

@ab3600456 In MSS, stimulus supports the AC. Whereas in PSA, AC supports the stimulus (bridges the gap between premise(s) and conclusion).
at first, I thought question two as a flaw/descriptive weakening stem, but here's my take on why it's a NA stem:
if the argument is based on an assumption, then it is necessary for the argument to stand
if you tear down that necessary assumption, then the support structure simply falls apart
to make this stem a flaw/descriptive weakening, it would need to say something like:
"Which one of the following describes a flaw/unreasonable assumption/gap in the reasoning?"

thank you, the best explanation ever
What is the difference between MBT and MSS? I keep getting the two mixed up.
To answer for the sake of answering:
MBT: is logically valid based on the statements in the question stimulus.
MSS: often is the conclusion of the statements in the question stimulus.
NVM - I found it on the next page!
Coming back after covering the next lesson:
MBT: The correct answer relies on no assumptions
MSS: The correct answer may rely on a small assumption
#22, isn't this a SA question stem? I am getting SA and MBT confused...
They are asking for a proper inference from the stimulus. It's a MBT question stem.
