Q) Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.

A. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.


Yes its between B and E.

B looks like just a formal statement.
E - emphasizes on the 99%, which is important here.

Just using my ear, i am picking E. But, would like to know exact error with B.

Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.

A. Five species of creatures have appeared on Earth, nearly 50 percent of them vanishing.
B. Nearly 50 percent of five species of creatures that appeared on Earth have vanished.
C. Vanished are nearly 50 percent of the five species of creatures that appeared on Earth.
D. Of five species of creatures that have appeared on Earth, nearly 50 percent of them have vanished.
E. Of the five species of creatures that have appeared on Earth, nearly 50 percent have vanished.

We have established that A and C are incorrect.
So I've taken out the hard stuff to try to simplify this question. (Please note "To try to" rather than "to try and")

I would say that B is incorrect, because the tenses are not consistent. "Appeared" goes with "vanished" (no 'have').

In D, "Of five" is incorrect. When you are identifying a subset of the population in the subsequent clause, the "five" actually serves the same function as "group" or "set", but has a numerical value.
So you would say, "Of the class of children we brought to the park, 50% were covered in dirt when they returned home".

In E, the two 'Of' are unrelated. They just happen to be the same word, meaning different things. Similar to the example of that that.
Also E fixes the issue from B, where the tenses were different. These are both past.

These are jsut my thoughts, I'd welcome some feedback. I've often found it useful to identify the "filler" in these SC questions and then work with the most simplistic version of the phrase - obviously needs to be done carefully to avoid changing the meaning. Just delete all adjectives.

P.s. Also I think that this sentence is very unclear anyway - it would be much better is we knew whether the species all appeared at the same time. A indicates that they appeared over a period of time, whereas B indicates that the species appeared all at once.

I would go with D, (stated below)

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.

the "them" clearly refers back to "species"

where as in E.

E. Of the five hundred million different species of living creatures that have
appeared on Earth, nearly 99 percent have vanished.

the use of "have" is plural, but the subject is "the five hundred million different species" (it's singular because of the "the") so it doesn't make sense.

that's my just 0.02. sucks there is no OA, would love to know the right answer =)

Awesome question. OA is E

I remember this pattern from following SC. Same applies here.

Although about 99 percent of the more than 50 million Turks are Muslims, the republic founded by Mustafa Kemal Ataturk in 1923 is resolutely secular.

a. Although about 99 percent of the more than 50 million
b. Although about 99 percent of over 50 million of the
c. Although about 99 percent of more than 50 million
d. Despite the fact that about 99 percent of more than 50 million
e. Despite the fact that about 99 percent of over 50 million

OA : A


99 percent of the more than 50 million
Of the five hundred million different species ---> this SC.

According to my source (GMATPrep), OA is D.
The issue I have with E is that I dont really like "99 percent". 99 percent of what?? I have seen other OE ruling out this kind of construcions.
please clarify.

Hey All,

I got asked to take this one on by Private Message. Apparently, it has appeared in three different threads, none of which have resolved. So I'm going to be adding this exact post to all three threads. Be aware if you see it repeated!

Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.

A. Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
PROBLEM: First off "nearly 99 percent..." appears to be modifying "Earth," when we want it to modify "five hundred million different species." Secondly, "vanishing" is not correct on its own, as it is a present participle and we'd prefer some kind of perfect tense (because the vanishing started in the past and continues into the present).


B. Nearly 99 percent of five hundred million different species of living creatures that appeared on Earth have vanished.
PROBLEM: It should be "THE five hundred million different species," otherwise it sounds like there have been more than five hundred million species, but we're just talking about a particular subset of them which happens to include five hundred million species. Also, the use of the simple past tense for "appeared" is wrong, because this should be present perfect (they have appeared starting in the past and CONTINUING into the present).

C. Vanished are nearly 99 percent of the five hundred million different species of living creatures that appeared on Earth.
PROBLEM: As fun as it can be to speak like Yoda, inverting the sentence is highly awkward. Again, the simple past tense "appeared" is incorrect.

D. Of five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent of them have vanished.
PROBLEM: It should be "THE five hundred million different species," otherwise it sounds like there have been more than five hundred million species, but we're just talking about a particular subset of them which happens to include five hundred million species. Also, it's redundant, and thus wrong, to say "of five hundred..." AND "...of them". We don't need both.

E. Of the five hundred million different species of living creatures that have appeared on Earth, nearly 99 percent have vanished.
ANSWER.

Hope that helps!

Hi tommy ,
Plesae consider the following sentence
He ran into the building,determined to save his puppy.
What is "determined"modifying ?
Also in the second bolded part ,Please tell me can a present participle be only used 1)as an adverbial modifier when it follows the comma after a clause
I crossed the pool,swimming with all my might.
2)as a modifier modifying the noun before it
The car going down the street is red
3)as a gerund
4) with "was/is/are/am" to indicate the progressive tense.
I was running.
I am running.

What is the function of the present participle in the following sentence
The leader came in a car,with his bodyguards following suit.

B and C combine the past tense appeared and with the present perfect tense have vanished. The sequence of events is unclear. If the species appeared in the past, how can they still be vanishing in the present? Eliminate B and C.

In A and D, it's not clear whether them refers to species or to living creatures. Eliminate A and D.

The correct answer is

Hey Munda,

He ran into the building,determined to save his puppy.

"Determined" is modifying "he", so this would not be a preferred way to write this. We'd prefer to see the participle touching the noun.

You seem confused about the difference between a participle and words with -ing. Words ending in -ing can be participles, gerunds, or participles that are part of progressive tenses.

PARTICIPLES

Present participles are generally adverbial when they follow the comma after a clause.

I crossed the pool,swimming with all my might.

In your example, "swimming" is iffy. You could argue it's modifying "crossed" (the way in which the crossing occurred), but it's really modifying "I". Just like the last one, it's not the cleanest way to write it.

The car going down the street is red

In this version, there's no comma. Participles with no commas always modify whatever they're touching. Very straightforward.

GERUNDS

Participles and gerunds are totally different words (adjectives versus nouns). They may look the same, but they're homonyms, with different meanings. Gerunds are nouns, not adjectives.

PROGRESSIVE TENSES

I was running. (this is really a participle with the past tense verb)
I am running. (this is really a participle with the present tense verb.

The leader came in a car,with his bodyguards following suit.

"following suit" is an idiom meaning "doing the same". This is just a participial phrase modifying a noun (no comma), "bodyguards."

Hope that helps!

To illustrate how the insertion of a comma can change what a modifier is modifying (and thus change the meaning of the sentence):

John kicked the puppy, upsetting Mary.

The purpose of the comma is to show that upsetting is modifying not the puppy but John. John is upsetting Mary (by kicking the poor, defenseless puppy).

Let's see what happens when the comma is removed:

John kicked the puppy upsetting Mary.

With the comma removed, upsetting is now modifying the puppy. The puppy is upsetting Mary. In this sentence, John might in fact be pleasing Mary by kicking the annoying puppy.

The big question I ask myself when I see a participle that ends in -ing:

Who or what is performing the action of the verb?

If I can't tell who or what is performing the action of the -ing participle -- or if the wrong thing is performing the action -- I eliminate the answer choice.

One question: I have read that the construction PREPOSITION + NOUN + PARTICIPLE is always incorrect in the GMAT.
Ex.- With child-care facilities included bla bla bla.

Could you corroborate that?

kanhaiya, Werewolf.- please, provide your reasoning. If not, is better to say nothing.

Thanks.



The concept and reasoning behind the correct answer were very well explained by Tommy Wallach, a Manhattan instructor. I feel that he has covered all aspects and there are other quality discussions as well that talk about several different aspects of the problem. So I felt that I didn't need to add anything from my side.

Since i am fast approaching my test date, I left a comment in this thread so that I will know in the future that I have already come across and solved this question. Is that a problem? I'm new to forums and I don't know all the rules. Am I not allowed to post only the answer?

Good remark. It's the absence of "the" that changes the meaning of the sentence in B.

E: conforms to the original sentence that there were only 500M species initially.

Ans: "E"

I would have chosen E but I cannot seem to find a logical explanation to eliminate B other than the fact that it does not contain "have appeared". Can someone clarify if my reasoning is correct..


Yes, that is another good reason that suggests E is better.

have appeared - means the species are still appearing
appeared - means they appeared once and don't appear anymore.
two different meanings.

Also, mba4viplav made a good point about the article "the"
absence of "the" changes the meaning.

I ate the 10 chocolates someone gave me. -- Here someone gave EXACTLY 10 chocolates.
I ate 10 chocolate someone gave me. -- Someone may have given me more than 10 chocolates and I ate 10 out of that.

Likewise,
Of the five hundred million different species of living creatures -- there are TOTAL 500M different species. No more, no less.
Nearly 99 percent of five hundred million different species of living creatures -- TOTAL may be more than 500M.

Calling all experts!!!
Agree to all the explanations provided regarding the usage of "the" above. But my question is that shouldn't we stick ourselves to the intended meaning, which says that there were more than five hundred million different species.....?

Please help me resolve this issue.

I think 'E' is better. After going through different posts, the points I have noted are :

1) B states that 99% of 500 million creatures appeared on Earth. Implies that 1 % appeared some where else but not on Earth.
2) B uses past tense 'appeared' which implies a completed action. Where as E uses present perfect tense (action started in past and still going on) and is apt because 1% exist even today.

Please correct me if I am wrong.

Thanks,
Amit

(Nearly 99 percent of five hundred million different species of living creatures) that appeared on Earth have vanished.
or
Nearly 99 percent of (five hundred million different species of living creatures) that appeared on Earth have vanished.
Not sure what is meant.

and
2) As per the original choice :
Five hundred million different species of living creatures have appeared on Earth, nearly 99 percent of them vanishing.
So it says species which are still appearing -> Present perfect usage and that is the tense used by E.
