• How to make a complicated list in English using colons and semicolons
A semicolon joins two independent clauses (no coordinating conjunction!) and delineates items in a complicated list.→ most native speakers do not know about this rule. Native speaker or not, you just have to learn how to use it.
List: X blah blah blah; Y blah blah blah; and Z blah blah blah.The structure, rendered horizontallyFull sentence + colon: complex list item #1 + semicolon; complex list item #2 + semicolon; AND complex list item #3.
The structure, rendered verticallyIntroduction to list:
item #1 that may be detailed and contain phrases or examples set off by commas;
item #2 that may be detailed and contain phrases or examples set off by commas;
AND item #3 that may be detailed and contain phrases or examples set off by commas.
The structure, rendered horizontally, with some words for contextAmericans sometimes eat strange combinations of foods: toast with peanut butter, banana, and honey; waffles topped with syrup and fried chicken; and pizza with onions, ham, and pineapple. One last time, the simplest versionFULL SENTENCE, probably setting up a list: item 1; item 2; and item 3.
• Split #1: at the end of one part of a complicated list, use a semicolon, not a comma, to separate the list elementsIn options A, C, and E, a semicolon rather than a comma should be used at the end of the first list item, this way:
In order to transfer media across a home from a computer to a television, three items are needed: a media source, or server,
that contains all the media like pictures, music, and videos; a receiver . . . ; and a translator . . . .Eliminate A, C, and E
→ in options A and C, in order to introduce examples,
such as is preferred to
like→ in option E,
two semicolons are missing.
→ Option E also needs a semicolon after "which new smart TVs often do"
Commas are not enough to separate list items when the list is complicated.
→ in option C, the first
which should be a that,
-- even though a comma precedes
which (and would precede that)
because that comma flanks and is connected to the appositive
a server. → corrected: THAT contains all the media pictures, music, and videos;
→ don't worry too much about whether
--the information is essential (and hence should be delivered with
no commas) or nonessential (in which case, use COMMA + which)
ELIMINATE A, C, and E
• split #2: option B vs. option DOption D contains a number of errors.
D)
which contains all the media
like pictures, music, and videos; a receiver that supports the DLNA standard,
that new “smart” TVs often do; and a translator, which will convert files to a readable format.
• the first
which should be a that (don't overthink this issue; I know of only one recent question that requires you to decide the that/which issue, and as is the case here, other errors exist)
• to introduce examples,
such as is preferred to
like• the word
that should not be preceded by a comma (because "that" signals essential information and this comma signals nonessential information)
Option B is better. Option B
-- correctly sets off the three items with semicolons;
-- uses
such as rather than
like before a list of examples; and
-- uses [comma + which] before
new smart TVs often do.Option B is better than option D.
Eliminate D.
The best answer is B.NOTESLet's analyze option B a bit.
→ B)
In order to transfer media across a home from a computer to a television, three items are needed: a media
source (, or server,)
that contains all the media such as pictures, music, and videos;
a receiver that
supports the DLNA standard, which new “smart” TVs often
do;
and
a translator, which will convert files to a readable format.
(1) the phrase (, or server,) is an allowed parenthetical insert that refers to
source and is
not actually connected to the word "that."
We therefore ignore the commas that flank the phrase "or server" when we analyze the word "that"
Read the sentence as " . . .
three items are needed: a media source . . . that contains all the media such as pictures, music, and videos; . . .(2) the verb "do" can stand in for almost any verb in the English language. "Do" = "supports the DLNA standard."

I still have few doubts :
1) How smart TVs DO the standards? IMO TVs can follow the standards but Is it ok to write TVs do the standard?
Um, the smart TVs are not "doing" the standards.
There's no such thing as "doing" a standard.
DO =
supports the DLNA standard. → a receiver that
supports the DLNA standard, which new “smart” TVs often
do In other words, the smart TVs DO support the standards
The pro-verb
do is sort of like a generic verb that can stand in for almost any verb.
→ substitute the actual verb back in:
. . . a receiver that supports the DLNA standard, which new "smart" TVs often support; . . .
That works.
So DO = SUPPORTS

2) Media source that contains...a receiver that supports ..and a translator, which will convert
Can we say the above three entities are parallel?
Sure. A list must contain similar grammatical parts of speech (all nouns, in this case)—not identically phrased constructions.
It's okay if one item of three does not contain "essential" modification by a that-clause.
A list would also be parallel if we had 1) adjective + noun; 2) adjective + noun; and 3) noun.
So, too, is this list parallel: 1) noun + essential relative ("adjective") clause; 2) noun + essential relative ("adjective") clause; and 3) noun + nonessential relative (adjective) clause
Quote:
P.S: I am not challenging the author of the question, I am just curious to learn about the above usage. Cheers!
It's usually fine to challenge an author, especially when it's done so politely, as you have done here . . .
We can tell the difference between curious challenge and righter-than-thou silliness.
Wait. Rephrase. It's okay to challenge an author
unless the author is GMAC.
Of course I must say this part (to all of you): if the question is official—never, never, never question the correct answer.
You are wasting your time.
GMAT answers are always correct.
Better to spend your time figuring out
why the answer is correct.
