Error on p. 148 of the LSAT Logical Reasoning Bible?

[SarahR]

I noticed that on p. 148 of the LSAT Logical Reasoning Bible, the conditional statement "A if B" is diagrammed as: A --> B

However, on the left-hand-side margin, it rightly states that " 'if' introduces a sufficient condition." As such, shouldn't "A if B" be diagrammed: B --> A ?

Also, the same page states that "A only if B" should be diagrammed: B --> A

However, I would think that this would be the reverse, as the conditional indicator, "only if," modifies "B," which would mean that the sentence should actually be diagrammed: A --> B

Is what is stated on p. 148 correct or is this an error? Please explain.

Thanks,
Sarah

Hi Sarah,

That's a pretty old error that we corrected some time ago (a few years, I believe). So, yes, that was an error, and we took care of it

Considering that you appear to be using an old version of the book, you may want to look on the books website--see the address on page 2 of your book--for the old errata list. there are only a few items (and none of those errors are in any recent version), but that may help you out.

Thanks!
