LSAT 102 | Section 4 | Logical Reasoning: Q2

LR Question 2 Explanation

QUESTION TEXT: Twenty professional income-tax advisors were given identical…

QUESTION TYPE: Must be True

FACTS:

1. Twenty income tax advisors were given the same tax form to fill out.
2. They all did it differently, and 19 of them were technically incorrect.

ANALYSIS: This is a very small sample, so there isn’t much we can conclude. Most of the wrong answers make blanket statements about all tax advisors.

There’s really only one thing we can conclude: tax advisors aren’t perfect. Nineteen of the twenty made mistakes. So at least those nineteen make mistakes.

___________

1. Who knows? Twenty is a small sample. The actual accuracy rate might be higher or lower.
2. CORRECT. This is true. We know that at least nineteen tax advisors are capable of bungling tax returns.
3. There’s not much support for this. Nineteen of the tax advisors weren’t much help in ensuring tax returns were correct.
4. We only know about twenty tax advisors. Maybe the rest are more accurate. And one of the twenty made no mistakes.
5. The tax advisors don’t give us much evidence that this is true. Nineteen out of twenty couldn’t get things right.
