you're welcome.

Dear @RON can you help me to explain this question:

I found that in this question:
"With no natural predators and expanses of green suburban neighborhoods that allow no hunting, wildlife officials estimate the New Jersey deer population to have grown to exceed 175,000.
A. With no natural predators and expanses of green suburban neighborhoods that allow no hunting, wildlife officials estimate the New Jersey deer population to have
B. With no natural predators and with expanses of green suburban neighborhoods that do not allow hunting, wildlife officails' estimate of deer population in New Jersey has
C. With no natural predators and with expanses of green suburban neighborhoods where there is no hunting, the Deer Population in New Jersey, wildlife officials estimate, has
D. Without natural predators and no hunting allowed in expanses of green suburban neighborhoods, New Jersey has a deer population that wildlife officials estimate to have
E. Without natural predators and with expanses of green suburban neighbourhoods where there is no hunting, wildlife officials in New Jersey estimate a deer population that has"

The OA is C and i see that the OA using this structure " with xxx and with xxxx" to maintain parallelism

However, i don't understand that in this question :
Because of wireless service costs plummeting in the last year, and as mobile phones are increasingly common, many people now using their mobile phones to make calls across a wide region at night and on weekends, when numerous wireless companies provide unlimited airtime for a relatively small monthly fee.
A. Because of wireless service costs plummeting in the last year, and as mobile phones are increasingly common, many people
B. As the cost of wireless service plummeted in the last year and as mobile phones became increasingly common, many people
C. In the last year, with the cost of wireless service plummeting, and mobile phones have become increasingly common, there are many people
D. With the cost of wireless service plummeting in the last year and mobile phones becoming increasingly common, many people are
E. While the cost of wireless service has plummeted in the last year and mobile phones are increasingly common, many people are

OA is D. Why the GMAC don't use WITH the cost of wireless service plummeting in the last year and WITH mobile phones becoming increasingly common ???
I eliminate the question D because i think that it does not parallelism

[RonPurewal]

This animal lives in grass and trees.
...perfectly parallel
('grass' and 'trees' are the parallel elements)

This animal lives in grass and in trees.
...also perfectly parallel
('in grass' || 'in trees')

both are correct. you will never have to decide between them.
same deal for 'with X and Y' vs. 'with X and with Y'.

[RonPurewal]

the only exception occurs if 'X' and 'Y' act in tandem—in other words, together—and they do NOT have the same effect separately.

e.g., let's say that, if you heat substance X AND shake it, it can explode (but you have to do both things; if you just heat it, or if you just shake it, it will NOT explode)

then...

*With heating and with agitation, substance X can explode.
--> incorrect; implies that these act individually

With heating and agitation, substance X can explode.
--> correct.

[RonPurewal]

see also #71 in OG 13th/2015, in which the same issue arises (with 'of', not 'with').
in that problem the word 'combination' is explicitly there, so the incorrectness of using two 'of's is much easier to detect.

Hi Ron,
Can we also eliminate E because "mobile phones are increasingly common" is missing "becoming"?

Thanks

[RonPurewal]

i like the sentence better with 'becoming', but i wouldn't go so far as to say the sentence is wrong without it.

...but that choice starts with a transition that makes no sense ("While...").
that's hard to miss, since it's the first thing there. so, there's no need to contend with this other (non-)issue.

Hi Ron,
Always thank you for the clarification.
