LSAT Logical Reasoning || with 100% Error-free Solutions.
A ________ assumption is enough, on its own, to validate the conclusion correct answers
sufficient
A ________ assumption is required for the argument to hold, but may not be enough on its own
for the argument to hold correct answers necessary
assumption family wrong answer characteristics correct answers Premise booster
Conclusion redundancy
Opposite
Out of scope
Reverse logic
premise booster correct answers repeat/support what the premise states
conclusion redundancy correct answers repeats conclusion
opposites correct answers hurt the argument
out of scope correct answers fall outside of scope of argument
reverse logic correct answers reverse order of desired logic (incorrect contrapositive)
steps to answer assumption family questions correct answers 1. identify the core: premise ->
conclusion
2. evaluate the logic, does it hold?
3. what is the gap?
4. work wrong to right
necessary assumption question stems correct answers required for the argument
argument depend on
must be assumed
characteristics of necessary assumptions correct answers 1. do not need to fill the entire gap
2. correct answer will often eliminate a competing possibility
3. if you negate the correct answer, destroys argument
4. may not be able to predict answer
if an argument has several potential problems, often there are several __________ assumptions
correct answers necessary
sufficient assumption question stems correct answers conclusion follows logically if it is
assumed
characteristics of sufficient assumptions correct answers 1. correct answer must fill the entire gap
, 2. almost always will be able to predict answer
on easier _________ questions, the answer will be stated in concrete terms correct answers flaw
flaw question stems correct answers reasoning error
fails to consider
most accurately expresses a flaw
argument is flawed because
vulnerable to criticism
argument above is flawed
correlation does not cause _________ correct answers causation
if A and B happen together, what does that not prove? correct answers A causes B / B causes A
if A and B happen together, the causal relationship between A and B could be: correct answers
explicit or implicit
explicit causal relationships correct answers blank thus causes blank (states causation)
implicit causal relationships correct answers blank thus blank (assumes causation)
flaws = correct answers assumptions
how do you check your work in flaw questions? correct answers connecting the flaw back to the
assumption
strengthen question stems correct answers most strengthens the argument
most supports the argument
does the most to justify the argument
strengthen the argument except
how to strengthen the argument correct answers 1. directly bridge the gap (makes the assumption
true) or 2. brings in an element that validates the assumption (could be something new)
weaken question stems correct answers most weakens the argument
most calls into question
does the most to undermine the argument
weakens the argument except
how to weaken the argument correct answers 1. disconnect the premise from the conclusion
(negates assumption) or 2. bring in an element that weakens the assumption through a specific
point (could be something new)
how would YOU weaken the argument? correct answers negate the assumption
