Both the caribou and the reindeer belong to the species Rangifer taran

Is 'have' agreeing with '7000 years of domestication'?

If not, I'd go with B

Can someone pls provide a detailed explanation.
Nitya, the manhattan link points to a different question

In option A have agrees with reindeer that is plural


(B) belong to the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency to circle in tight groups, which is different from caribou that tend

a couple of problems with B. Have refers to 7,000 years of domestication changing the meaning. Also which lacks a clear antecedent and the comparison is not parallel

Removing modifiers you have

reindeer's tendency is different from caribou that tend.

you're comparing the tendency to the caribou, making this option incorrect.


(C) belong to the species Rangifer tarandus, but being domesticated in Eurasia for about 7,000 years has developed reindeer's tendency to circle in tight groups, and that is different from caribou tending


it's not clear what "being domesticated" refers to. Lack of parallelism in the final part " and that ...." because that is suppose to refer to tendency but if you add "and" it does not work.


(D) are the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency
to circle in tight groups, while the tendency is for caribou

This option as B, says that the years,not the domestication, have developed the reindeer's tendency.

while caribou tend to is preferred to while the tendency is for caribou to

Also the comparison is not properly established.


(E) are the same species, Rangifer tarandus, but being domesticated in Eurasia for about 7,000 years has developed the reindeer's tendency to circle in tight groups, which differs from caribou tending

wrong comparison between tendency and caribou.
being domesticated .... lacks clear referent

ask back if you have more questions.

I would go with A -- the other choices are just awkward/don't make sense :S If the OA is B, can you please share the source as well?

Edit: Looks like A is indeed right; sorry for not reading through the thread, I'm obviously going to bomb DS.

OA is A, this is a GMATPrep question.

(B) belong to the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency to circle in tight groups, which is different from caribou that tend


is seems that 7000 years of domesticatioon developed reinders tendecy ...
awkward meaning

7000 yers of domestication can't develop reinders tendesy )

This is a great meaning based question if you don't understand the meaning you will pick the incorrect choices!

Meaning Analysis:

Caribou and reindeer belong to rangifer tarandus, but after 7000 years, reindeer have developed a new habit to move around in tight circles while caribou tend to spread far and wide.

Only A does this perfectly.

Option B says domestication have developed... Makes no sense

Option C same thing

Option D and E says both are same species


Though I have one question shouldn't it be Reindeer's have?

Can someone please clarify this. Thanks!

(A) belong to the species Rangifer tarandus, but after 7,000 years
(B) belong to the same species, Rangifer tarandus, but about

Can somebody please explain when to put the comma and when to ditch it?
I am a bit confused when i comes to the usage of comma.

If the statement were a s stated above, what is the difference and which one to choose?

There is no enough evidence to choose between those two statements. Do not restrict your view on this question: B is not correct because suggests that "7,000 years have developed" (no sense).

(A) belong to the species Rangifer tarandus,
(B) belong to the same species, Rangifer tarandus,

are the same; B uses a thing called appostive modifier: the part between the commas explains or/and identifies a preceding word, and to see if this is used correctly you can substitute the part between the commas into the word it refers to, like this

(B) belong to the same species Rangifer tarandus, : same as A.

So I would not base my choice on this.

Zarrlou, i understand the question and agree to the answer,

this was just a general doubt, which always lingers in my mind OR
this was just a general doubt which always lingers in my mind

Can you please suggest which of these is correct

Your examples are very different: do not get confused! In the above example there is no better answer.

In the above example, the modifier "explains" a word. Example

Caesar, the emperor of the Roman Empire, did something...

The modifier "explains" who Caesar was and must be placed between commas.

In this new example you are not "explaining" a word: you are not using an appostive modifier.

this was just a general doubt, which always lingers in my mind
The part after the comma does not explain what a doubt is. This is a complete different thing. To make this clearer an appostive modifier would make the sentence look like this
this was just a general doubt, a point about which noone is certain the next part explains what a doubt is.
this was just a general doubt which always lingers in my mind

In this new example you are using a which modifier, so it should be preceded by a comma.

Hope it's clear

here it doesnt make any difference but i encountered a similar thing :

if you preface someone's name with a noun describing their occupation (or other word describing what that person does), WITHOUT AN ARTICLE, you DO NOT use a comma.

if there's an article, you DO use a comma.

if it's an adjective, you DO use a comma.

example:
Jazz pianist and composer Thelonious Monk ... --> correct
A jazz pianist and composer, Thelonious Monk ... --> correct
Creative and original, Thelonious Monk ... --> correct

hope it helps.

Boils down to A & B
In ‘B’ ‘domestication in Eurasia have developed reindeer's tendency’ seems Eurasia have developed the tendency, But actually tendency was develop by reindeer itself, as intended in original sentence. Eliminate this.

So ' A' is correct in IMO

Both the caribou and the reindeer belong to the species Rangifer tarandus, but after 7,000 years of domestication in Eurasia, reindeer have developed a tendency to circle in tight groups, while caribou tend to spread far and wide.

(A) belong to the species Rangifer tarandus, but after 7,000 years of domestication in Eurasia, reindeer have developed a tendency to circle in tight groups, while caribou tend
(B) belong to the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency to circle in tight groups, which is different from caribou that tend
(C) belong to the species Rangifer tarandus, but being domesticated in Eurasia for about 7,000 years has developed reindeer's tendency to circle in tight groups, and that is different from caribou tending
(D) are the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency to circle in tight groups, while the tendency is for caribou
(E) are the same species, Rangifer tarandus, but being domesticated in Eurasia for about 7,000 years has developed the reindeer's tendency to circle in tight groups, which differs from caribou tending




Hello Guys, above is a question which I found very difficult to be solved quickly. How can you do it quickly? I solved it in 1:30 minute but I think it was just luck. I didn't look at it thoroughly enough. May be you think my timing good enough, but I just had my GMAT last week and bombed my Verbal. I only got a 29 in Verbal. For your information, I know most of the SC rules which I should know, I had around 10-15% error if not timed. However, I perform badly under time pressure. The reason why I find this type of question difficult is because almost the whole question is covered in the answer. Sometimes you just can't really rely on the splits because you have to consider the meaning of the whole questions.

This is how I do it:

1.) Read the original question quickly and grasp the meaning, try to identify some potential error.
2.) Scanned the choices for splits
3.) First one I noticed was the "belong to the/ are the same species" . Both seemed correct but they may change the whole sentences structure, therefore i had no other choice but to look at them one by one (which wastes a lot of my time) I knew XXX are XXX is a bit suspicious in GMAT but I was not confident to use this as a split.
4.)
A: "reindeer have developed ....., while caribou tend " not exactly parallel in tenses (present perfect vs present) but acceptable, hold
B: wrong use of modifier, relative pronoun issue, compare "tight groups" with "Caribou"
C: "and that is different.." awkward sentence structure, no antecedent for "that"
D: run-on sentences, awkward structure, "while the tendency is for"
E: suspicious word "being", compare "tight groups" with "Caribou", relative pronoun issue

How's my approach? Is it the fastest and the most appropriate way? I found it very time consuming when I realize I couldn't use the splits to eliminate the answer with POE. Any suggestions? Cheers!

Gordon

A seems best here: belong to the species Rangifer tarandus, but after 7,000 years of domestication in Eurasia, reindeer have developed a tendency to circle in tight groups, while caribou tend

faults with others in bold:

(A) belong to the species Rangifer tarandus, but after 7,000 years of domestication in Eurasia, reindeer have developed a tendency to circle in tight groups, while caribou tend
(B) belong to the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency to circle in tight groups, which is different from caribou that tend
(C) belong to the species Rangifer tarandus, but being domesticated in Eurasia for about 7,000 years has developed reindeer's tendency to circle in tight groups, and that is different from caribou tending
(D) are the same species, Rangifer tarandus, but about 7,000 years of domestication in Eurasia have developed reindeer's tendency to circle in tight groups, while the tendency is for caribou
(E) are the same species, Rangifer tarandus, but being domesticated in Eurasia for about 7,000 years has developed the reindeer's tendency to circle in tight groups, which differs from caribou tending



this is not correct . it is definitely awkward but not run on !!



well if you are answering it confidently then i do not think that you should be overtly concerned with timing .

What is the source?

Hi Gordon,

This is how I did it in 1:01 minutes.

1. looking at vertical split, Eliminate D & E : are the same species is wrong.
2. Look at C, last word of the sentence says tending, which is clearly wrong in the current sentence formation. Also on a second thought, I saw "but being domesticated in Eurasia for about 7,000 years has developed reindeer's tendency" - reindeer's tendency wasn't domesticated. hence Eliminate C
3. but about 7,000 years of domestication in Eurasia have developed - should be has. Eliminate B.

I hope this helps

Thanks for showing how you did it, it was very useful. However, I wonder whether using POE from vertical split would miss any potential answer. For instance, A is not entirely parallel, I may make a mistake by eliminating A or any another answer if it look awkward in the first place. How do you avoid it?

Additionally, it is easy to remove choices according to Subject verb, but sometimes the subject can change from singular to plural. In that case, both answers may be correct. How can you ensure you won't fall into this trap? THat's why I always read to whole sentence before I confirm my answer.

Cheers, Gordon

In my experience NO, I have done quite a many exercises and vertical split always worked for me. If the first first word does not agree with the sentence construction, How can it be correct? Vertical splits help u eliminate redundant dysfunctional sentences where u might feel the need to dispose time locating the mistake.

When You read the question and u get the gist of what the subject and the verb are, post which u can eliminate the obvious errors for eg. :
The clothes is in the washing machine (BAD)
The clothes are in the washing machine(thumbs up)
The cloth are in the washing machine(BAD)
The cloth is in the washing machine(thumbs up)

Though I always believe you should read the sentences quickly once even if you've found the errors. won't take u more than 15-20 secs to reconfirm what you're doing is correct.

Thanks, trying to explain it to the best of my ability

Cheers!
