What is a sufficient assumption?
This question asks you to identify a sufficient assumption—that is, an assumption that, if added to the argument, would make it logically valid. We’re looking for something that would fix all of an argument’s problems, bridging the gap between what the support justifies and what the conclusion claims.
What is a necessary assumption?
Necessary assumption questions ask you to determine what has to be true—but was never explicitly stated—in order for an argument to work. Stated differently, if a necessary assumption were discovered to be false, the argument would fall apart—the conclusion would not follow logically from its premises.
What words or phrases indicate a necessary assumption question stem a sufficient assumption stem?
Solving for Necessary Assumption If this were a necessary assumption question, the question stem would include words like “relies,” “depends,” “requires,” etc., indicating that the answer choice MUST BE THERE for the author to draw a conclusion.
How do you answer sufficient assumption questions LSAT?
The question asks us to prove the conclusion. The way to answer sufficient assumption questions is to arrange the evidence, find the gap, and add a new premise that lets you draw the conclusion. Here, conditional logic is key, but this will not always be the case.
How do you identify an assumption?
One of the most reliable ways to find assumptions is to look for shifts in language between the premises and conclusion of an argument. When new stuff appears in the conclusion that wasn’t discussed in the premises, it usually got there by way of an assumption.
How many necessary assumption questions are on the LSAT?
There, now you’ve seen how to negate the answer choices. It’s basically a foolproof strategy for finding the answer. There’s one big problem. If you did all this work on each assumption question, you would have 10 minutes to do the other 23 LR questions.
What is a sufficient condition LSAT?
The sufficient term is the part that immediately follows “if.” “Sufficient” means “enough,” and this part of a conditional statement is sufficient—it’s enough—to require the other part. You don’t need any additional information to know that the other part is true.
How many questions are on the LSAT assumption?
What is the difference between sufficient and necessary conditions?
A necessary condition is a condition that must be present for an event to occur. A sufficient condition is a condition or set of conditions that will produce the event. A necessary condition must be there, but it alone does not provide sufficient cause for the occurrence of the event.
What is the difference between necessary and sufficient conditions examples?
Definition of “sufficient condition” For example, while air is a necessary condition for human life, it is by no means a sufficient condition, i.e. it does not, by itself, i.e. alone, suffice for human life.
