If you have no keyboarding skills at all, you will not be able to use a computer. And if you are not able to use a computer, you will not be able to write your essays using a word processing program.

Summary
If you have no keyboarding skills, then you will not be able to use a computer. If you are not able to use a computer, then you will not be able to use a word processing program to write your essays.

Notable Valid Inferences
If you are able to use a word processing program to write your essays, then you have keyboarding skills.

A
If you have some keyboarding skills, you will be able to write your essays using a word processing program.
Could be false. We don’t have any conditional statements in the stimulus to tell us what occurs when a person does have keyboarding skills. Our first conditional statement tells us what occurs when a person does not have keyboarding skills.
B
If you are not able to write your essays using a word processing program, you have no keyboarding skills.
Could be false. We don’t have any conditional statements in the stimulus to tell us what occurs when a person is not able to use a word processing program. Not being able to use a word processing program is a necessary condition, it is not a sufficient condition.
C
If you are able to write your essays using a word processing program, you have at least some keyboarding skills.
Must be true. As shown below, this answer choice is the correct contrapositive of our conditional chain.
D
If you are able to use a computer, you will probably be able to write your essays using a word processing program.
Could be false. The only statement we could infer if a person can use a computer is that that person has keyboarding skills. This answer choice is an incorrect contrapositive.
E
If you are not able to write your essays using a word processing program, you are not able to use a computer.
Could be false. We don’t have any conditional statements in the stimulus to tell us what occurs when a person is not able to use a word processing program. Not being able to use a word processing program is a necessary condition, it is not a sufficient condition.
