Parallelism

well if are attempting 10 questions in 10 mins ,you have to give each question in 1 min each ,well most of us don't do it but in a ideal situation this is what we should do.Equality has been the cornerstone of our society and so is the GMAT.
GMAT and CAT both  require strong foundation in English Grammar.See what i just did ,i gave equal importance to both gmat and cat.

Consider

Some bat caves, like honeybee hives, have residents that take on different duties such as defending the entrance, acting as sentinels and to sound a warning at the approach of danger, and scouting outside the cave for new food and roosting sites.
(A) acting as sentinels and to sound
(B) acting as sentinels and sounding
(C) to act as sentinels and sound
(D) to act as sentinels and to sound
(E) to act as a sentinel sounding

here all except B violate parallelism by using the infinitve to
check out how defending and scouting(present participial) are in parallel ,so sounding is the best answer.InE sentinel is singular not in sync with residents(subject verb agreement).


another one
The only way for growers to salvage frozen citrus is to process them quickly into juice concentrate before they rot when warmer weather returns.
(A) to process them quickly into juice concentrate before they rot when warmer weather returns
(B) if they are quickly processed into juice concentrate before warmer weather returns to rot them
(C) for them to be processed quickly into juice concentrate before the fruit rots when warmer weather
returns
(D) if the fruit is quickly processed into juice concentrate before they rot when warmer weather returns
(E) to have it quickly processed into juice concentrate before warmer weather returns and rots the fruit

The only way .. to salvage X ...is to process..,now  citrus is singular and doesn't agree with them and they  ,so setence A is wrong.B,C,D have reference errors ,E is best as it uses parallel infinitives and uses fruit to directly refer to citrus.
