LR Question 22 Explanation, by LSATHacks

QUESTION TEXT: Congenial guests and a plentiful supply of good things…

QUESTION TYPE: Flawed Parallel Reasoning

CONCLUSION: Sylvia’s dinner party will be a success.

REASONING: Congenial guests and good food will ensure a successful party. Silvia has congenial guests and lots of food.

ANALYSIS: Silvia’s food might not be good.

Abstractly, the flaw is: forgetting to a key term in a sufficient condition.

___________

1. This is a good argument. Emily has properly combined the right ingredients.
2. This is a bad argument. George might not know how to bake corn. But it doesn’t make the mistake made in the stimulus: forgetting a key term.
3. This is a good argument. Andrew did everything right.
4. CORRECT. This makes the same error of forgetting a key term. We don’t know if Andrew’s meat stock is well-seasoned.
5. This is a bad argument. Washing fresh greens is a sufficient condition, but not a necessary condition. So Tisha might be able to make a fresh salad even without washing. But this argument doesn’t make the stimulus’ error of forgetting a key term.

Recap: The question begins with “Congenial guests and a plentiful supply of good things”. It is a Flawed Parallel Reasoning question. Learn more about LSAT Flawed Parallel questions in our guide to LSAT Logical Reasoning question types.
