But unlike most Small mammals, bats are long-lived (up to 30 years or more for some species), and most species produce only one young per year. Scientists ... Bats do not benefit tequila drinkers alone. Important agricultural and commercial plants like bananas, balsawood, breadfruit, chicle (for chewing gum), cashews, dates, figs, mangoes, and vanilla also rely on bats for pollination and seed dispersal.

I chose (d).
I thought when semicolon is used, an independent clause should be followed after. Thus, (a), (b), (c) were excluded from the list per my thought.

I guess a semicolon can be used to list certain items to make a sentence parallel. Am I right?

Hi All,

Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

(a) as it is from the above
(b) pollinating banana, breadfruit, and mango trees; and indirectly helping to produce
(c) pollinating banana, breadfruit, and mango trees; and they indirectly help to produce
(d) they pollinate banana, breadfruit, and mango trees; and indirectly help producing
(e) they pollinate banana, breadfruit, and mango trees: indirectly helping the producing of

The confusion regarding the use of semicolon in this sentence is very valid. So far, we have seen construction in which semicolons are always followed by independent clauses. However, here we have phrases that are connected through semicolon. In fact, in this sentence semicolons have been used as comma to separate various entities in a parallel. This does not mean that semicolon will not perform the earlier function anymore.

In this sentence, we have too many commas because every entity in the parallel list has three examples. If there were commas all across the sentence, it would be little cumbersome to identify the entities in the parallel list. then Hence, use of semicolon becomes imperative here to distinguish between the examples of a particular entity and the next entity in the parallel list.

Needless to say that option B is the correct answer because this is the only choice with all parallel entities in the list – aiding…; pollinating…; and helping….

Now use of colon in choice E is not correct because after the first entity there is a semicolon and this must be maintained throughout.

Hope this helps.
Shraddha

Hi
Let me take a dig on it.

Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

(a) as it is from the above
(b) pollinating banana, breadfruit, and mango trees; and indirectly helping to produce
(c) pollinating banana, breadfruit, and mango trees; and they indirectly help to produce
(d) they pollinate banana, breadfruit, and mango trees; and indirectly help producing
(e) they pollinate banana, breadfruit, and mango trees: indirectly helping the producing of

First of all gauge the meaning of the sentence. Let the meaning guide you the errors.

The sentence talks about the roles that Tropical bat plays. i.e it is a list of roles. Remember List must be parallel. Also, check the word "And" before the phrase" indirectly help produc[/u]e tequila by pollinating agave plants." This should also give you an indicator about some parallelism issue. Check for it

As per sentence,What are the roles that bat plays -
aiding in the....[ing form}
pollinating banana..{ing form}
AND
and indirectly help produce {verb}
Hence the list is not parallel. Check for the options now
Clearly B is the answer

Now, you said D - You thought that D is answer since semi colon introduces Independent clause. However, check for the last part of sentence, it also have semicolon(below sentence) before the bold part. But, No independent clause follows it. Hence, option D is also Incorrect.
they pollinate banana, breadfruit, and mango trees; and indirectly help producing


First of all look for major errors in sentence and then go for sentence structure.

But, MGMAT SC Pg 191

"semicolon connects two closely related statements. Each statement MUST be able to stand alone as an independent sentence."

I guess there are exceptions then.

There are two uses of semi-colon:
1) If two independent clauses are closely related, then in such a case we use semi-colon to separate the two clauses and not period.
2) If there is a list and if in that list again there are entities separated by comma, then it would be quite difficult to separate the items of list and entities. For such cases, usage of semi-colon becomes a necessity.

Apart from these two cases, there is no other usage of semi-colon.

hi abhimahna,

Can you please tell me, what is wrong with the original sentence:

Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

aiding --> verb
pollinating --> verb
help --> verb

Is it that in || ism the tense also has to be maintained?

Definitely a trick used by GMAC here, to test on not so known information about "semicolons"

As Manhattan says: a minor use of the semicolon is to separate items that themselves contain commas

So I think there are two things to keep in mind when it comes to semicolons:

1. Used to connect two independent clauses
2. Used to present a list that involves number of comma's to separate the items in the list

Hi Folks,

Hoping you all can clarify why we can separate with semi-colons here when the clauses are seemingly not independent? The correct answer here is B but I chose D(it just seemed the most right). Any clarification would be great!

25. (Book Question: 692)

Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

A. pollinating banana, breadfruit, and mango trees; and indirectly help produce
B. pollinating banana, breadfruit, and mango trees; and indirectly helping to produce
C. pollinating banana, breadfruit, and mango trees; and they indirectly help to produce
D. they pollinate banana, breadfruit, and mango trees; and indirectly help producing
E. they pollinate banana, breadfruit, and mango trees; indirectly helping the producing of

Explanation

Correct Answer: B Selected Answer: D

Logical predication; Parallelism This sentence expresses a list of the roles tropical bats play in the rain forest ecosystem. Since these roles are enumerated in a list, and since the first member of the list is already provided, it is necessary to maintain the same structure for the rest of the members of the list in order to maintain parallelism and clarity. Note that semicolons separate the members of the list, leaving the commas to mark series of items within each member of the list.

A In this version, the third member of the list does not maintain the -ing verb form that the two previous members use.
B Correct. This version correctly maintains the parallel structure (aiding in . . .; pollinating . . .; and helping . . .).
C In this version, the third member of the list does not maintain the -ing verb form of the two previous members of the list. In addition, this member of the list includes a subject (they) while the other members do not, again violating parallelism.
D In order to maintain parallelism the verb that is the member of the list has to be in the -ing form, not its complement. Thus, the -ing has to be on the verb help, not on produce.
E Although this version maintains parallelism throughout, the phrase helping the producing is an incorrect construction in English.

Just my 2 cents : I think semicolon is not used ONLY for separating independent clauses. The semicolon is also used to separate lists which contains many connectors. In this case, all of the lists have their own list. So basically the main function is to prevent the messiness because we have so many AND.

By the way, I really believe that we have previous discussion about this question. You can google it first to see complete discussion.

I understand how option B is correct is correct taking into consideration that semicolons can also be used when there are lists within lists or when too many commas have been used.

Now, w.r.t to this rule, can someone please explain why is option D wrong. As I see it, the second semicolon correctly joins 2 independent clauses and the 3 semicolon correctly joins two lists as there are lists within these lists inside the second clause.

Also, the meaning of the sentence doesnot change as the lists in option B describes how bats help. In option D, the first list does d same as do the lists after the 2nd semicolon.

Expecting an explanation by an expert.

aiding in the dispersal is not parallel with they pollinate banana... and help producing tequila ...



In D, why do we need to consider parallelism between aiding in the dispersal and they pollinate banana? As I have mentioned earlier, we can treat they pollinate banana...as a separate clause altogether. In that case, parallelism is not required between " aiding in the dispersal and they pollinate banana"

Hi aviejay, the sentence starts by stating that Tropical bats play important roles in the rain forest ecosystem. Thereafter, three different ways are suggested in which Tropical bats play important roles, all three related by virtue of three parallel Participial phrases.

Hence, parallelism is crucial here.

Hello Everyone!

This looks like an excellent example of a list question you would see on the GMAT exam! Let's start by taking a close look at the question, and highlight any major differences between each option in orange:

Tropical bats play important roles in the rain forest ecosystem, aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce tequila by pollinating agave plants.

(a) pollinating banana, breadfruit, and mango trees; and indirectly help produce
(b) pollinating banana, breadfruit, and mango trees; and indirectly helping to produce
(c) pollinating banana, breadfruit, and mango trees; and they indirectly help to produce
(d) they pollinate banana, breadfruit, and mango trees; and indirectly help producing
(e) they pollinate banana, breadfruit, and mango trees: indirectly helping the producing of

After a quick glance over the options, 3 major differences appear:

1. pollinating / they pollinate
2. help / helping
3 produce / producing


Instead of tacking one issue at a time, let's first take a look at the type of sentence we're dealing with - a LIST QUESTION. Whenever we see a question that deals with a list on the GMAT, it's a major hint that we're going to deal with PARALLELISM!

One of the list items is not underlined: aiding in the dispersal of cashew, date, and fig seeds

The correct option MUST be written using parallel structure that matches the non-underlined part of the sentence. Let's see how each option holds up in terms of parallel structure:

(a) aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly help produce --> NOT PARALLEL

(b) aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and indirectly helping to produce --> PARALLEL

(c) aiding in the dispersal of cashew, date, and fig seeds; pollinating banana, breadfruit, and mango trees; and they indirectly help to produce --> NOT PARALLEL

(d) aiding in the dispersal of cashew, date, and fig seeds; they pollinate banana, breadfruit, and mango trees; and indirectly help producing --> NOT PARALLEL

(e) aiding in the dispersal of cashew, date, and fig seeds; they pollinate banana, breadfruit, and mango trees: indirectly helping the producing of --> NOT PARALLEL

Option B is the only one that follows parallel structure by using -ing verbs to introduce each item on the list, so it is the correct choice!
