Really confused by the extent to which we rely on diagram in this question. For PF questions, when is the case that we do not strictly follow the diagram in the stimulus? https://classic.7sage.com/lsat_explanations/lsat-44-section-2-question-22/
STIMULUS:
H–>/G
——-
H /G (confirm one theory at the expense of the other)
However, AC E:
D–>/J
——–
/D–>J (either or)
If the above is true, why is AC E is still the correct AC? Or in this case, are we choosing the best AC?

conceptual gap on logic :(
AC C is the correct answer
analysis:
The first sentence is a conditional statement:
Murderer--> at the office
H and S at the office
H committed --> H's Fingerprint or H's Footprint
S committed --> /(S's Fingerprint or S's footprint)
[S's Fingerprint OR S's footprint --> /S committed]
fingerprint- not H's
/Footprint
inference:
/Fingerprint (not H's) and /footprint at all --> /H committed
Missing:
Either (the first conditional statement has not been activated. )
There are only S and H to choose from!
Or (we connect the second gap)
We found the fingerprint at the office is S's fingerprint
------
S is the killer
Stimulus:
premise:
/cannot distinguish homophones --> /accurate conversion
conclusion:
/improve recognize and utilize --> /accurate conversion
missing:
/improve recognize and utilize --> /cannot distinguish homophones
=
can distinguish homophones --> improve tech to recognize and utilize
Then, of course, it is also necessary that "can distinguish homophones --> improve tech to recognize"
AC A is the correct answer
AC D: mistaken reversal
AC E: it might be the author's assumption, but (1) we have no evidence to support it (2) it is not the real flaw of the argument
yes. it is an explicit causal chain, but I am unsure of calling this inference valid as under the same scrutiny for conditionals.
AC reading error: complex sentence lolll
AC C: Researchers are more likely to pursue lines of research [that they expect will favor theories (that) they accept] than to pursue other lines of research
note:
-This is saying the pursuit of lines of research instead of saying those researchers favoring data that align to theories they accept.
- we also do not know whether those researchers in AC C accept Jones's theory
AC D: does not address the puzzle: while researchers examine and detect errors, why do the detected errors tend to be those that disfavor Jones's theory? Telling me that there are always some errors that remain undetected does not address the puzzle!
AC B: another way of saying that researchers just show bias to favoring Jone's theory, tending to detect fewer errors in data that fits Jones's theory = they give more attention to those data that do not conform to J's theory
stimulus:
PO+ AM --m--> A
PO
-----
A --> likely AM
AC B:
Car+AA--m--> EP
Car
------
EP-->likely AA
AC A: offers a competing alternative hypothesis/explanation for the phenomenon
AC D: still does not address the issue of the ultimate source of the gold found in the artifacts: do the older artifacts still use the gold dugged from the mine?
So in this case, we can solve the question by using either principle or analysis in the stimulus.

Can someone explain AC D?
if you write AC D as "a being with practical intelligence --> get what it wants entirely through the use of its practical intelligence"and negate it to "/ get what it wants entirely through the use of its practical intelligence --> /a being with practical intelligence", it seems to me that AC D also connects the premise and the conclusion?
I would appreciate any input! Thanks in advance!
I actually felt like this question was harder :(
To remind myself:
For the Parallel Method question, we are trying to understand the underlying logic of the author and, sometimes, have to give charitable assumptions to do so.
"(A+B) --> C--> OR -->/A
------
(A + B) is unsustainable
* there is no intermediary conclusion
* this whole conditional chain is the premise for this argument
The element "C" (considerations as remote... of an offense) itself is not a premise supporting the argument; rather, the " (A+B) --> C" (it implies that considerations as remote as what an offender did years ago are relevant to the seriousness of an offense) is part of the premise for the argument.
reduction v. suppression of acid production
irritate your stomach v. adversely affect the function of your stomach
stimulus:
lighter roasted less NMP
darker roasted more NMP
caffeine stimulates acid production that irritates the stomach
NMP suppresses the acid production
-------
conclusion: darker roasted coffee irritates the stomach less than the lighter roasted coffee
gap: two things affect the acid production; we only know the amount of NMP (factor 1 ) present in lighter roasted and darker roasted coffee but have no idea about the amount of caffeine (factor 2) present in lighter roasted and darker roasted coffee. You cannot assume that they have the same amount of caffeine (this cannot be the default assumption as it is at the core of the argument and needs to be supported by the stimulus. )

Can someone explain AC D?
negating AC D: "in most cases, valid wills do adequately meet the needs of the person for whom the wills were prepared"
Would it be an unwarranted assumption that "the needs of the person for whom the wills were prepared" include a need to tailor their wills to their circumstances? Because if that is the case, I think negated AC D also wrecks the argument. If all valid wills can achieve this (again, both software and lawyers get you the valid wills), then the author cannot conclude that lawyer's expert advice is ALWAYS worth paying for.
CORRECTION.
After watching the explanation: AC A is incorrect in terms of confusing "ought + failed" with "/ought", and similarly confusing "promise + failed" with "/promise"
One "fails" to do something is not the same statement as that one "cannot" do something.
premise:
- a given promise to meet friends
- cannot keep this promise to meet friends (the initial trouble I have is mistakenly putting an → between these two elements as if they formed a conditional relationship)
*missing:
a promise --> obligation to keep a promise *
conclusion:
(ought to do --> can do) not always true = ought to do & cannot do
Correct AC D: Promise --> obligation regardless of whether the promise can or cannot be fulfilled
Incorrect AC A:
cannot (ought) --> cannot (promise)
[but the stimulus premise gives us an example of promise. Only NA activated. We want the SA though...]
Recharge after eating lunch lol...
NC Local --> excuse acceptable (defendant is unsure which set of law applies, confusion thus might help remove the penalty)
NC National
(NC NATIONAL --> NC LOCAL) [thus we confirm that confusion does not arise from the case in which you violate the national law]
(LOCAL LAW --> NATIONAL LAW)
-----
/ excuse acceptable (confusion does not apply and thus there still could be a penalty)
AC C:
Justified --> K
sometimes Justified
?
-------
/ (K --> /FP)
===========
Justified --> K
sometimes Justified
K --> FP (straightforward give the answer lol )
or
J --> FP
(again, because "sometimes" we are justified: J, K, and FP)
-----
it is possible that (K --> FP) [alternatively, it is possible for "K +FP"]
puzzle: severe drought --> below normal rainfall-->more fire, yet less financial damage than the areas with relatively normal rainfall...
AC B: compares areas subject to fire v. areas subject to few fire: the former is denser in population.
But does the former, necessarily, have below normal rainfall, and, necessarily, are the type of regions with severe drought? The same question can goes toward the latter areas as well. AC B requires us to draw this series of illicit assumptions.
