OG 11 SC # 19

by punitkaur » Sat Oct 10, 2009 5:22 pm
While depressed property values can hurt some large investors, they are potentially devastating for home owners, whose equity - in many cases representing a life's savings- can plunge or even disappear.

Isn't "they" ambiguous? The OG says its not and clearly refers to depressed property values. How do you decide when a pronoun reference is ambiguous and when its not.

I am having major trouble in such kind of problems.

Please help.

Thanks.

There is a little known rule that I remember from Ron Purewal.
The pronoun (mostly subject pronoun) in the second clause (in our case 'they') is presumed to refer to the subject of the previous clause if the the tense, etc agrees.

You can PM Ron to get more info.

I used to have similar doubts but I started resolving these ambiguities logically.
If we try to understand the structure of the sentence the pronoun "they" can refer to either "depressed property values" or "some large investors".
Now try to understand the meaning of the sentence. In the present context "some large investors" can not potentially devastate "home owners". Hence, "they" can only refer back to "depressed property values" and there is no pronoun ambiguity.

Regards,
Nikhil.

just identify the subject of the sentence..and you will not have any trouble with pronouns..;-)

what is the sentence "talking" about? identify that.

hi - i got a p.m. asking me to respond here.

you should know that pronoun ambiguity is not an absolute rule. in other words, the test will clearly tolerate a certain degree of pronoun ambiguity.

in general, we've found:
the gmat will tolerate pronoun ambiguity when both of the following are satisfied:
1. the intended referent makes much more sense than do the other possible referents,
and
2. the intended referent is PARALLEL TO THE PRONOUN, and the other possible referents are NOT parallel to the pronoun.


in this case, both of these are true.
#1, it would be ludicrous for "they" to refer to large investors.
#2, "depressed property values" is the SUBJECT of the opening clause and "they" is the SUBJECT of the underlined clause, thereby creating parallelism. (note that "large investors", the phrase you've picked as a competing antecedent, is NOT the subject.)

--

two more things:

* this is not OG11 #19, it's OG verbal review (1st edition - the purple book) #19.

* i'm curious why, of all the problems involving pronoun ambiguity, you chose this one as an illustration - since the ambiguity is a total non-issue here.
ALL the choices that make any sense have either "they" or "their"; the others have "it", which couldn't refer to anything at all.

Thanks Ron. I think I understand the rule better now.

Earlier, when reading a sentence, if I found more than one noun followed by a pronoun , I was blindly focussing on the sentence structure rather than checking whether the sentence was already making sense or not.

In other words, I was trying to apply the rule taking for granted that if 2 nouns were followed by a pronoun reference[without checking for subject etc], I thought it to be ambiguous. I was not paying attention to the meaning of the sentence.

After reading the two points you provided and going back to solve the problem stated in this post, it makes sense to me that this problem is too simple to get confused :), as you stated.

I hope I will be able to apply the explanation you provided to other complex problems and see if I understood things correctly now.

Thanks!

ok.

a couple more things:

* there should ALWAYS be ONE clearly intended antecedent. i.e., you should ALWAYS be able to figure out which noun SHOULD be the antecedent.
this is key. if you don't figure this out, go back until you do.

* i break pronoun ambiguity down into two types:
(1) OBVIOUS pronoun ambiguity: the pronoun is PARALLEL to the WRONG noun, and is NON-parallel to the noun that is clearly intended.
(2) all other pronoun ambiguity.

if i see (1), i eliminate.

if i see (2), i DON'T necessarily eliminate, unless i have literally exhausted ALL other avenues of eliminating answers.

hope that helps

Hi Ron,
I am still not able to apply the rules you mentioned in this post on the following question from the OG GMAT 12th edition.

In late 1997, the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed to visitors for cleaning and repair due to moisture exhaled by tourists, which raised its humidity to such levels so that salt from the stone was crystallizing and fungus was growing on the walls.
Options C,D, and E read:
(C) because tourists were exhaling moisture, which
had raised the humidity within them to levels
such that salt from the stone would crystallize
(D) because of moisture that was exhaled by
tourists raising the humidity within them to levels
so high as to make the salt from the stone
crystallize
(E) because moisture exhaled by tourists had raised
the humidity within them to such levels that salt
from the stone was crystallizing.

I have provided choices C,D, and E only because they're the ones relevant to the rule you explained (choices A and B were clear to me). OG says that them in choices C and D is ambiguous while it clearly refers to chambers in E. the chambers is a subject in the passive construction (the chambers inside the pyramid of the Pharaoh Menkaure at Giza were closed) while I couldn't classify "within them" as a subject in either C,D, or E. Would you please help me clarify why E is clear and how C, and D are not. How can apply your rule in this case? does "within them" play the rule of the subject here?
your help is greatly appreciated!I have spent lots and lots of hours just trying to understand the rules of pronouns and ambiguity of antecedent. Your answer will help me a lot!!

I think Ron's rule applies here correctly:
In both C and D, chambers and tourists are acting as subjects.
Let me rephrase C and D.....

C--> the chambers were closed to visitors becoz tourists (subject doing some action) were exhaling.....
D--> the chambers were closed to visitors becoz of moisture that was exhaled by tourists raising (again tourists doing some action)

E-->tourists is part of prepositional phrase and cannot be a subject. So them clearly modifies "the chambers."

Experts, correct me if I am not :)

This is a parallelisum problem as well and Option E is the OA "the stone was crystallizing and fungus was growing ".

Thanks group for enlightment on this anticedent rule of Subject preference.

Please correct me if I am wrong but this is a simple case of a subordinate clause...

this is a pretty good example of a situation that satisfies my #2 above:

as i said up there
if i see (2), i DON'T necessarily eliminate, unless i have literally exhausted ALL other avenues of eliminating answers.


in this problem, i would not even bother considering this pronoun issue, because there are still other avenues of solution remaining.
in particular, there is still a very well-defined parallelism issue: the non-underlined part contains "fungus was growing", so we need the underlined part to contain "salt was crystallizing". this is enough to eliminate (c) and (d), leaving (e).

i really meant what i said in that post -- the OG is not terribly consistent in its rules about pronoun ambiguity, so, unless you're looking at an extremely clear-cut case, you should ALWAYS look at anything else you can get your hands on first.

here's an alternative rule, which is much simpler to think about:

if you see an AMBIGUOUS PRONOUN that is SPLIT AGAINST A SPECIFIC NOUN -- i.e., it is replaced by a specific noun in other answer choices -- then you can probably feel safe in eliminating it.
if the ambiguous pronoun is NOT split against a specific noun, then you may want to think twice about eliminating it.

here, there's no specific noun in opposition to "them" (i.e., you don't see "them" vs. "those chambers" in other choices). so the ambiguity is not an issue worth thinking about.
