Hi guys, this is a set of 5 SC questions, the OA along with the OE will be posted 5-6 days from now.

Kudos to correct solutions (with explanations)!

1)During World War II the Department of Defense was the nation's largest employer, directly employing over 16
million soldiers who served in combat and thousands more support staffers who served the war effort domestically,
and which indirectly supported several million additional jobs through its extensive use of the manufacturing and
trasportation industries.

(A) During World War II the Department of Defense was the nation's largest employer, directly employing
(B) The Department of Defense was the nation's largest employer during World War II, which directly employed
(C) During World War II the Department of Defense was the nation's largest employer and employed
(D) The nation's largest employer during World War II was the Department of Defense was, directly employing
(E) During World War II the nation's largest employer was the Department of Defense, which directly employed

IMO E
Tests parallelism and modifiers

Two clauses "directly employing..." and "which indirectly supported..." should be parallel. so ans should contain "which directly employed"
Out of B and E, "which directly employed.." modifies Word War II in B which is wrong.

Thus E.

thus A

hence D

5) Since companies are rethinking their portfolios for the post crisis world, they should ask themselves if they are still the best owner of their assets.

(A) Since companies are rethinking their portfolios for the post crisis world, they should ask themselves if they are still the best owner of their assets.
Since is not required, as the rethinking is not a cause of a reason
(B) As companies rethink their portfolios for the post crisis world, they will ask themselves if they still continue to be the best owner of their assets
Conditional verb is required, hence usage of will is wrong
(C) As companies rethink their portfolios for the post crisis world, they should ask themselves whether they are still the best owners of their assets
Correct
(D) As companies rethink their portfolios for the post crisis world, each of them should ask themselves if they are still the best owners of their assets
each of them should ask themselves, this does not match in numbers, it should be itself instead of themselves
(E) Although companies rethink their portfolio for the post crisis world, they should ask themselves whether they are still the best owners of their assets
Although is not required, changes the meaning

Zarrlou, can you distinguish between the usage of whether and if please.
Thanks ...

SOMEWHERE I READ WHEN EVER THERE IS SINCE IN THE SENTENCE WE SHOULD USE PRESENT PERFECT. Is this correct Zarrolou? Please shed some light.

Ya atalpandit, treat is a a rule, we should use perfect tense when we encounter since.
but remember this does not hold true, when since is used as a "because"

I hope i am clear.

Hi guys, here are the solutions of the set.

I awarded the deserved kudos to correct/good explanations, thank you for participating!

During World War II the Department of Defense was the nation's largest employer, directly employing over 16
million soldiers who served in combat and thousands more support staffers who served the war effort domestically,
and which indirectly supported several million additional jobs through its extensive use of the manufacturing and
trasportation industries.

(A) During World War II the Department of Defense was the nation's largest employer, directly employing
(B) The Department of Defense was the nation's largest employer during World War II, which directly employed
(C) During World War II the Department of Defense was the nation's largest employer and employed
(D) The nation's largest employer during World War II was the Department of Defense was, directly employing
(E) During World War II the the nation's largest employer was the Department of Defense, which directly employed

Analysis: this question shows you the importance of reading the whole sentence. The not underlined part has a "and which" that is an indicator of parallelism: options B and E have this construct. However as which refers to the preceeding elegible noun in E it refers to war => clear error.
The other options: C uses "and" as connector, which give us the idea of two separate facts, and options A and D do not respect the parallel structure of the sentence as stated above.
OA E

_____________________________
Contrary to popular belief, bats are not blind, and in fact are among the most sensory animals on the planet;
they use sonar to locate prey, and their ability to communicate adially at wide range of frequencies assists them
in mating, helping them to distinguish their own species from that of others.

(A) assists them in mating, helping them to distinguish their own species from that of others.
(B) assist them in mating, helping them to distinguish their own species from that of others.
(C) assists them in mating, helping them to distinguish their own species from those of others.
(D) assists their mating, helping them to distinguish their own species from those of others.
(E) assists them in mating, helping them to distinguish their own species from of others.

Analysis: since the subject is singular, "assists" is the correct option. You can't use "those of" because otherwise your sentence would look like this: "distinguish their own species from the species of other species".
OA E

_____________________________
An extract of the plant Decalepis hamiltonii, which has proved helpful in protecting brain cells from damaging effects
of alcohol
, is grown across India, where it has been used in traditional folk medicine for centuries.

(A) An extract of the plant Decalepis hamiltonii, which has proved helpful in protecting brain cells from damaging effects of alcohol,
(B) An extract, which has proved helpful in protecting brain cells from damaging effects of alcohol, comes from the plant Decalepis hamiltonii,
(C) A Decalepis hamiltonii extract, which has proved helpful in protecting brain cells from damaging effects of alcohol,
(D) The Decalepis hamiltonii plant has an extract, which has proved helpful in protecting brain cells from damaging effects of alcohol,
(E) The Decalepis hamiltonii plant, an extract of which has proved helpful in protecting brain cells from damaging effects of alcohol,

Analysis: here is another example of a sentence that can be solved correctly only by looking at the not underlined portion
Since it states "is grown" the only subject of this action can be the plant => not the extract.
OA E

_____________________________
Since 1992, when the board of directors voted to allow inside salespeople's commissions to be based on how the entire
department performs as a whole, several regional offices began
setting department goals prohibitively high, with a goal to
incite individual competition and prevent against freeloading.

(A) inside salespeople's commissions to be based on how the entire department performs as a whole, several regional offices began
(B) inside salespeople's commissions to be based on the performance of the entire department as a whole, several regional offices began
(C) that the commission of inside salespeople be based on how the entire department performs as a whole, several regional offices have begun
(D) commission of inside salespeople to be based on the performance of the entire department as a whole, several regional offices have begun
(E) that inside salespeople's commissions be based on the performance of the entire department as a whole, several regional offices began

Analysis: the word "since" is usually an indicator of an action that sarted at a given time in the past, but whose effect/ that continues in the present => present perfect is required.
OA D

_____________________________
Since companies are rethinking their portfolios for the post crisis world, they should ask themselves if they are still the best owner of their assets.

(A) Since companies are rethinking their portfolios for the post crisis world, they should ask themselves if they are still the best owner of their assets
(B) As companies rethink their portfolios for the post crisis world, they will ask themselves if they still continue to be the best owner of their assets
(C) As companies rethink their portfolios for the post crisis world, they should ask themselves whether they are still the best owners of their assets
(D) As companies rethink their portfolios for the post crisis world, each of them should ask themselves if they are still the best owners of their assets
(E) Although companies rethink their portfolio for the post crisis world, they should ask themselves whether they are still the best owners of their assets

Analysis: The word "since" is not correct as there is no cause-effect relationship. "Although" is incorrect because there is no contrast.
Option B uses a future tense, and option D uses "each of them should ask themselves" => each cannot ask themself.
OA C

Hi ankurgupta03,

whether VS if

if we want to make a long story short here is the tip: GMAT prefers "whether", especially after a prepositions.

"If" is used to express a conditional clause, "whether" expresses a "choice".
In this particular sentence "whether" is used to express a choice, a "question", and is prefered to "if", refer here for more about this topic : http://gmat-grammar.blogspot.it/2006/07 ... vs-if.html

Questions like these tell you why you need to read the whole statement is SC

Some of the underlined options will stand correct if alone and only E maintains the ||'sm here so E .

for #2, I don't understand why 'those' is redundant or incorrect. i read option C to say:

"helping them to distinguish their own species from those (species) of others"

meaning, helps them decipher their type of bat from everyone else (not just other bats)

In Option C, "those" refers to "species" - so does "others" - hence the redundancy. Option C is thus as follows:

"...helping them to distinguish their own species from those (species) of others (other species)." ....."species of other species" does not make sense - ("others" cannot refer to "other animals" since the word "animals" does not occur in the sentence.)
