Errata list - Manhattan LSAT 2nd edition LOGICAL REASONING

[noah]

Hi everyone, I am re-posting Mike's post below so that it's the first one you see when you get here!

Here is the running list of all the typos, formatting issues, etc. in the first print of this 2nd edition book.

Almost all of the issues are very minor -- there are very few that you actually need to be concerned with, and we've listed them in bold at the front of the list.

HUGE thanks to rippinradio for his brilliant editing eye and his attention to detail.

Please write in if you see anything else we've missed. We'll keep updating this list as need be, and of course we'll polish everything up for the next printing.

Finally, a big thank you to everyone for all the positive feedback we've been getting on this book! We put a lot of blood and sweat into it, and it's great to hear from so many people that they are finding it to be useful.

Here's the errata list:

Logical Reasoning Guide

On pg. 445, the analysis of choice (B) says that it is false. However, isn't it possible for it to be true?

Using the given example, let's imagine 5 voters.

Imagine 3 prefer A and 2 prefer B.

Out of those who prefer A, one finds school budgeting to be the most important issue. The other two are concerned with crime.

Out of those who prefer B, both find school budgeting to be the most important issue, but no one is concerned with crime.

This is a possible scenario in which at least some voters who prefer B do not share at least one common concern with at least one voter who prefers A.

Correct?

[ManhattanPrepLSAT2]

Hi - thanks for your question! --

(B) is a challenging answer choice, and I think I understand how you are thinking about it. I think the key is to interpret the wording exactly.

What it states is "At least some voters who prefer Candidate B do not share at least one common concern with at least one voter who prefers Candidate A."

In your example, you had two people in group (B) - let's think about them one at a time:

Person 1: Do we know for sure person 1 shares a common concern with at least one person who prefers Candidate A?

Yes we do -- she shares the common concern of school budgeting with one person who prefers Candidate A.

Person 2: Do we know for sure? Yes we do, for the same reasons.

So, in your example, both people in group B DO share at least one issue in common with someone in group A -- which leads answer (B) to be false.

Now, if (B) were worded slightly differently -- if it was worded either "At least some voters who prefer A don't share a common concern with voters who prefer B" or "At least some voters who prefer B don't share a common concern with ALL of the voters who prefer A" the answer would be very different.

Hope that is helpful in clarifying. Please let us know if it isn't, and I'll be happy to discuss further!

Right, I see what the statement is saying now.Thank you very much for the response! I appreciate this board; you guys rock.

Hi all -- the correct answer for #4 on PG. 364 should be (C) NONE OF THE ABOVE, and it is incorrectly labeled as (B).

Sorry everyone! We'll get that fixed up.

Just got my 2nd editions today. Is this thread to add in some more nitpicking? on P42 of the LR book the conclusion is stated "increase in detectors from 30% to 45% does not make home fires any less likely." In my opinion, it should read "does not make detection of home fires any less likely." What do you think?

[LSAT-Chang]

A minor error I found: RC Strategy Guide pg. 46 3rd-4th line from the top of the page: "For one, most of use (should be us) read much more actively..."

[noah]

And, here's one that someone sent in - thanks!

Didn't see this listed but in LG 2nd ed page 156 and 157, question 5 on page 156 says "neither Y nor Z can be odd...." but in the solutions on page 157 it says "neither Y nor Z can be even...."

The question is correctly printed, just the solution text is wrong.

[timmydoeslsat]

On page 486, the part entitled "1. Match the Reasoning" has a flaw.

The original has a valid conclusion, while the correct answer does not.

The correct answer goes from:

All children on playground are in the fifth grade
+
Lisa is on the playground
_____________________________________________
Lisa is in fifth grade.


We do not know that Lisa is not a parent or a teacher. Just a simple error of not stating that Lisa is a child.

Page 159 - "(D) recognix ze (recognize) that two different methods of investigation can yield identical results"

[ManhattanPrepLSAT1]

Thanks! got it...

[wsjstockstar]

On page 88 (LR Strategy Guide 2nd Edition), should the following sentence:

"Now, here's comes the really challenging stuff."

read as follows:

"Now, here comes the really challenging stuff."

[noah]

On page 88 (LR Strategy Guide 2nd Edition), should the following sentence:

"Now, here's comes the really challenging stuff."

read as follows:

"Now, here comes the really challenging stuff."

Now, that embarrassing.

Thanks for alerting us - we'll get that fixed for our next print run.

Hi - thanks for your question! --

(B) is a challenging answer choice, and I think I understand how you are thinking about it. I think the key is to interpret the wording exactly.

Yes we do -- she shares the common concern of school budgeting with one person who prefers Candidate A.

Person 2: Do we know for sure? Yes we do, for the same reasons.

So, in your example, both people in group B DO share at least one issue in common with someone in group A -- which leads answer (B) to be false.

Now, if (B) were worded slightly differently -- if it was worded either "At least some voters who prefer A don't share a common concern with voters who prefer B" or "At least some voters who prefer B don't share a common concern with ALL of the voters who prefer A" the answer would be very different.

Mike,
I was confused about B). I Tim's example :
3A and 2B
A = (2 -budgeting; 1 Crime)
B = (2- budgeting)
I see your point that "at least some voters who prefer B don't share a common concern with ALL voters who prefer A" is true. However, "at least some voters who prefer B do NOT share a common concern with AT LEAST ONE VOTER who prefer A" is ALSO true. (1 crime guy in A doesn't share common concern about budgeting) Just because one Inference is true, it doesn't mean that the second inference will be false. Correct?

I am still not clear why B) is incorrect. I see that it is not true, but it could be true.

Thoughts?

Is there a reason for why you switched from using regular text in explaining the answer choices to italicized text in explaining the answer choices on page 230? The book switches back to regular text on page 236.

Something small, but I think it would be better if the book is consistent in that regard. It kind of threw me off for a second, as I was thinking I was reading something else and not the description for why the answer choices were wrong/right. Consistency is clutch!

Just something to ponder, Noah.

Thanks!

[nmop_apisdn2]

Found another error.

On page 232, where it discusses the categories of incorrect answer choices for strengthen or weakening questions, it says: "If you can't see how the answer impacts the author's point, or if you can see the answer either strengthening or weakening the argument, depending on how you interpret the answer choice or on what assumptions you make, that's a good sign it neither strengthens nor weakens."

Shouldn't the bolded and underlined word be "can't"?


I think it should be.
