Error info in pg.317 & Pg.360

by RogerD345 Wed May 22, 2019 12:39 am

Hi. pg. 317, Drill. 53, 's Q.21's answer, i think it is reversed or Wrongly expressed.

Also, Small Request, can the administration people move my prior posting regarding 5lb practice drill to in this thread so anyone and everyone who study the material would benefit as well? Also, possibly grant another extra small tiny request regarding my prior request of PT.84 LG. Game 4, corporate Bonds, which on the web among serious LSAT students expressed difficulty of the game which i believe if Manhattan Prep explains most comprehensive breakdown manner possible, it will help Manhattan Prep's reputation.

This Q.20 of Pg.360 Drill.64), according to the explanation of 5lb, 20 should be Y cuz sufficient condition can occur regardless of timing and since sufficient condition occurred and necessary condition must occur which in this case, it didn't

pg. 317
Q21

Indeed, it is reversed. It should be,
~ES or ~CRO --> S
and
~S --> ES and CRO


And thanks for calling out
pg. 360, #20
which is also messed up.


In regards to this,
Also, Small Request, can the administration people move my prior posting regarding 5lb practice drill to in this thread so anyone and everyone who study the material would benefit as well?

We have talked about it and want to, however this forum (is very old and thus) does not make it easy to do that sort of thing. We've only missed a handful of them, and since you're asking lots of questions within a post (only some of which are in the subject line), I don't know that people would be able to usefully find those explanations anyway.

Also, possibly grant another extra small tiny request regarding my prior request of PT.84 LG. Game 4, corporate Bonds, which on the web among serious LSAT students expressed difficulty of the game which i believe if Manhattan Prep explains most comprehensive breakdown manner possible, it will help Manhattan Prep's reputation.


I don't know what you're referring to here. I'm not sure whom you emailed / requested. I'm not in the NY office. It looks like there aren't any posts at all yet for PT84 game 4.

Are you able to create a new post? If so, you could just post a forum request there and say "Can anyone post a diagram?"

additi-Error info in pg.450 & 510 & 851 &867

addition-Error info in pg.450 & pg.510 & pg.851

I am sorry to upload another error in pg. 450 Q.15. I believe the answer should regards the new element in Q.15: Less than eighteen month.

Hi. Patatrick, I am requesting SO a student AND an instructor can post in the forum section of PT.84. LG. I cannot create a post there. I requested a post in PT.83. LG. Game 4 DIAGRAM Section, that MANHATTAN PREP will let an instructor to create a diagram in PT.84. LG. game 4, corporate Bonds. HAHA. BTW, Thx for replying me.

Hi. patrick. i believe Q.40 of pg. 510 (drill 89) is an error. it has pretty much same explanation as pg.511's q.48, which it is listed as False Choice in that page. but in pg. 510, q.40 is listed as possible vs certain.

Pg.851. Q.7 I am certain it is Y not N.

Pg. 867 Q.11, i don't think (A), is correct answer. cuz if sales prices go up, the demand would fall down even more (as the universal rule of economics)
Thx.

pg. 450 Q.15. I believe the answer should regards the new element in Q.15: Less than eighteen month.


Eighteen months isn't really a new element. It's just the math of saying "by the end of this year" + "six months".
A year = 12 months
By the end of this year = Less than 12 months (even if it's Jan 1, it's less than 12 months until the end of the year)

So "by the end of this year" (less than 12 months) + "6 months" = less than 18 months


i believe Q.40 of pg. 510 (drill 89) is an error. it has pretty much same explanation as pg.511's q.48, which it is listed as False Choice in that page. but in pg. 510, q.40 is listed as possible vs certain.


They're not the same, but I certainly wouldn't have labeled #40 as Possible vs. Certain. I would label that one and #48 as Causation Flaws, because to me that's the most germane label when an author has become too narrowly convinced of one causal possibility, even though other causal possibilities remain.

However, I see how the language in #48 could ALSO be described as False Choice.

EXAMPLE:
Jimmy is sneezing. Since he doesn't have allergies, he must be sick.

That is both a Causal Flaw (there could be some other reason he's sneezing) and a False Choice (who said that sneezing is ONLY caused by Allergies or Sickness? That's a false choice!)



Pg.851. Q.7 I am certain it is Y not N.


You're correct. I'm emailing Errata about it.


Pg. 867 Q.11, i don't think (A), is correct answer. cuz if sales prices go up, the demand would fall down even more (as the universal rule of economics)


Inversely proportional means that the two things go in opposite directions:
price goes up, demand goes down
or
price goes down, demand goes up

#11 has the demand going down, so we would be matching this principle if price goes up. The price DOES go up. So it is applicable.
(it's just a really counterintuitive principle to begin with, because who would ever claim that as demand goes up, price goes down?)
