(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

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?

A "Help produce" is not parallel.
B Correct.
C "Help to produce" is not parallel.
D "They pollinate" is not parallel.
E "They pollinate" is not parallel.

B. pollinating banana, breadfruit, and mango trees; and indirectly helping to produce - CORRECT only option with parallel structure "aiding", "pollinating" and "helping"

This is pertaining to the use of semi-colon to separate lists, and the maintenance of symmetrical present participle parallelism – aiding, pollinating and helping. These two functions are neatly done in B

But doesn't the use of 'indirectly' break parallelism?

Hi ameyaprabhu ,

This is acceptable in determining the parallel structures.

Indirectly is simply an adverb used to modify helping. So, we have aiding, pollinating and helping parallel to each other.

Thanks, my understanding was that if there is an adjective in one element, then all others also need adjectives

This is not mandatory in determining the parallel structures. It should not happen that you are comparing nouns with verbs or gerunds with verbs. But having adjectives in some and not in others is fine.

I hope that makes sense.

if we go by the logic,that D is right because it uses ";" as a IC separator then we find out that option D uses two subordinate conjunction back to back and hence makes it wrong.Kind of redundant.
And as I was confused by the use of semicolon I found that it can be used to separate parallel items.

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?

Hi ameyaprabhu, aiding and pollinating are not verbs; they are participles (specifically present participles).

Quote:

Not at all. Different parts of the sentence can be in different tenses.

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 Saumya2403,

The semi colon in the sentence will separate the sentences that talks about various things in a long sentence. For eg.

A group contains - AA, AB, AC
B group contains - BA, BB, BC
C group contains - CA, CB, CC

If I were to use all these groups along with their sub-group members in one sentence, then semi colon will help separate different groups.

The sentence will be: There are various products in groups such as AA, AB and AC; BA, BB and BC; and CA, CB and CC. Not to forget the last and will be a correct usage.

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

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.

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

OG2018 SC#692

We need a parallel structure here. "Aiding", "pollinating" and "helping" make perfect parallel structure. Only feasible answer is B.

Tough one! I could see why B is correct. Because of parallelism and the meaning the sentence is trying to convey. The sentence is about how bats play an important role in the rain forest ecosystem. The bats do this in 3 ways, aiding, pollinating & helping to produce. But, then, the first semi-colon is after seeds while according to me, it should be before aiding. Thus, should not the semi-colon be before aiding?
