Hello itzmyzone911
To end violent tendencies in young children, mothers want peaceful conflict resolution,
readily available counseling, and
decreasing the prominence of television
shows that contain abundant and often casual violence.
First split: You need to maintain parallel structure: mothers want X, Y, and Z. Because X and Y are NOUNS, Z must be noun too. Thus, option A, B are out because they use adjective form - decreasing. C, D, and E remains
Second split: C is clearly awkward because the verb-ing modifier "containing as they do often...." does not make any sense here. It does not modify a previous clause in any way. C is out immediately.
Third split: You have two ways to eliminate E.
(1) Back to the structure X, Y, and Z ==> Logically,
Z should be a noun phrase, NOT a clause. Option E, however, uses a
relative clause "THAT.....". If you are familiar with GMAT parallel structure, you can skip E very quickly. Please note parallel structure must be maintained strictly.
(2) Second approach, E is out because it
changes meaning, the original sentence use phrase "abundant
and often casual violence", but E uses "abundant
but often casual violence. E conveys a contrast idea that
"abundant violence" is good, but "casual violence" is not. This is not the intended meaning that
both "abundant violence" AND "casual violence" are not good. ==> E is out. Only D left and is correct.
(A)
decreasing the prominence of television shows that contain abundant and
often casual violence
Wrong.
(B)
decreasing the prominence of television shows containing often casual but
abundant violence
Wrong.
(C) a decrease of the prominence of television shows,
containing as they do often
casual violence in abundanceWrong.
(D) a decreased prominence of the abundant and often casual violence contained
in television shows
Correct.(E) a decreased prominence of television shows that contain abundant
but often
casual violence
Wrong.
Hope it helps.
