- When solving an assumption question, what are you finding?
Show answer
The hidden premise or intermediate step the argument depends on but does not state- How do you use the negation test to check if an answer is a correct assumption?
Show answer
Negate the answer choice; if negating it breaks the argument's logic, then it is the correct assumption- What is a sufficient assumption?
Show answer
An assumption where the argument only works IF this statement is true- What is a necessary assumption?
Show answer
An assumption that must be true for the argument to work, even though the argument might work in other ways too- What trap should you watch for when an answer choice supports only one premise?
Show answer
Confusing support for a single piece of evidence with an assumption the overall argument needs- Where do gaps and logical jumps typically occur in arguments?
Show answer
Between the evidence presented and the conclusion being drawn from it- In strengthen questions, what does it mean to strengthen an argument?
Show answer
To add new information that makes the conclusion more likely to be true- What is a common trap in wrong strengthen answers?
Show answer
An answer that just restates or reiterates a premise already mentioned in the argument- When looking for an answer that strengthens an argument, where should you focus?
Show answer
On the weakest link or the biggest logical jump in the reasoning- Should a strengthen answer ever contradict or introduce counterevidence to the conclusion?
Show answer
No; strengthen answers must always support the direction of the argument- What are methods you can use to strengthen an argument?
Show answer
Provide concrete examples, add relevant statistics, eliminate alternative explanations, or support hidden assumptions- In weaken questions, what does it mean to weaken an argument?
Show answer
To add new information that makes the conclusion less likely to be true- What trap should you avoid with answers that only disprove a single premise?
Show answer
Assuming that proving one premise false weakens the entire argument and conclusion- How do you most effectively weaken an argument?
Show answer
Attack the logical mechanism connecting evidence to conclusion, or challenge a key hidden assumption- Can weaken answers introduce entirely new information the argument never mentioned?
Show answer
Yes; new facts that undermine the conclusion are legitimate weaken answers
