Allison plays volleyball.
In logical reasoning questions, what is evidence? - Answer: Evidence is the information offered by an
author to support the conclusion.
In logical reasoning questions, what is an assumption? - Answer: An assumption is an unstated piece of
evidence that is required for a conclusion to be valid. An example of an assumption would be Allison is
over six feet tall, therefore she plays volleyball. Allison plays volleyball, is the conclusion.
In logical reasoning questions, what do weaken questions ask for? - Answer: Weaken questions ask for
info that can be added to the argument to make the conclusion less likely. An example of a weakening
argument would be that height can hinder a volleyball players performance.
What are 4 words or phrases that indicate a weaken question? - Answer: 1. Weaken
2. Calls into question
3. Casts doubt upon
4. Seriously damages
In logical reasoning questions, what do strengthen questions ask for? - Answer: Strengthen questions
ask for information that can be added to the argument to make the conclusion more likely. An example
of a strengthening argument would be that only volleyball players over six feet tall can block over the
net.
What are 2 words or phrases that indicate a strengthen question? - Answer: 1. Strengthen
2. Support
, In logical reasoning questions, what do flaw questions ask for? - Answer: Flaw questions want you to
determine the error the author makes in going from the evidence to the conclusion. There are
numerous different common flaws that appear on the LSAT.
What are the 8 common flaws in logical reasoning questions on the LSAT? - Answer: 1. Unwarranted
Assumption, 2. Necessity versus sufficiency,
3. Representativeness, 4. Scope Shift, 5. Alternative possibilities, 6. Causation versus correlation, 7.
Opinion versus fact, 8. Number versus percentage
Unwarranted Assumption - Logical Reasoning Flaw - Answer: Assumptions based on insufficient
evidence. An example is her battery works; therefore her battery is charged. The unwarranted
assumption is that the battery working is the only thing needed to ensure the phone is charged.
Necessity versus Sufficiency - Logical Reasoning Flaw - Answer: A flaw of deeming a sufficient action as
necessary. An example would be saying if we break up, I will unfriend him on Facebook. Breaking up
might be sufficient reasoning to unfriend someone, but breaking up is not required to unfriend him.
Representativesness - Logical Reasoning Flaw - Answer: Assuming something as representative of a
dissimilar population. An example would be saying when I was a child, mint ice cream was my favorite
flavor; therefore I will serve that at your birthday. However, your preference is not representative of
everyone.
Scope Shift - Logical Reasoning Flaw - Answer: When a conclusion presents information not present in
the evidence. An example would be saying only 10 percent of children have been to Washington D.C.;
therefore kids don't know a lot about government. This conclusion presents a shift in scope.
Alternative Possibilities - Logical Reasoning Flaw - Answer: The conclusion fails to consider other possible
arguments that could alter events. An example is: If Olivia is in class, she turns her cell phone off;
therefore if her cell phone is off she is in class. This fails to consider Olivia may have her phone off for
other reasons.
Causation versus Correlation - Logical Reasoning Flaw - Answer: A conclusion correlates 2 unlike events
while failing to explain causation. An example is: In the summer, the Carr family goes swimming often
and also eats ice cream; therefore, swimming makes them eat ice cream. Here causation is not
explained.
