LSAT 117 | Section 3 | Logical Reasoning: Q7

LR Question 7 Explanation

QUESTION TEXT: If you have no keyboarding skills at all, you will not…

QUESTION TYPE: Must be True

FACTS:

1. If you have no keyboarding skills then you can’t use a computer.
2. If you can’t use a computer then you can’t write your essay on a word-processing program.

ANALYSIS: The contrapositive is: If you can write your essay on a word-processing program then you can use a computer and you must have computer skills.

Stick to the contrapositive and you won’t go wrong.

Here are the statements in diagram form:

No Keyboarding ➞ can’t use computer ➞ can’t use word processing program

Word processing ➞ can use computer ➞ some keyboarding.

___________

1. Not necessarily. Keyboarding skills are just a necessary condition for computer use. You might not have a computer to write with even if you have keyboarding skills.
2. This is the reverse of A and also wrong. If you’re locked in jail with no computer then you couldn’t use a word processing program even if you type very well.
3. CORRECT. WP ➞ can use computer ➞ some keyboarding. 
4. Hard to say. Using a computer is just a necessary condition. You might not have access to a word processing program. 
5. This is the reverse of D, and equally wrong. There could be other reasons you can’t write your essay apart from not being able to use a computer. Maybe you can’t read or write (but can keyboard).
