38. Scientists have observed large concentrations of
heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the
growth of industrial activity there.

(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there

the answer is d, but why ?

2. Since 1981, when the farm depression began, the number of acres overseen by professional
farm-management companies have grown from 48 million to nearly 59 million, an area that is about

(A) have grown from 48 million to nearly 59 million, an area that is about Colorado's size
(B) have grown from 48 million to nearly 59 million, about the size of Colorado
(C) has grown from 48 million to nearly 59 million, an area about the size of Colorado
(D) has grown from 48 million up to nearly 59 million, an area about the size of Colorado's
(E) has grown from 48 million up to nearly 59 million, about Colorado's size

why the answer is C ? before that it's plural ? so we must use have ?

199. Because the Earth's crust is more solid there and thus better able to transmit shock waves, an earthquake
of a given magnitude typically devastates an area 100 times greater in the eastern United States than it
does in the West.

(A) of a given magnitude typically devastates an area 100 times greater in the eastern United States than it
does in the West
(B) of a given magnitude will typically devastate 100 times the area if it occurs in the eastern United States
(C) will typically devastate 100 times the area in the eastern United States than one of comparable
magnitude occurring in the West
143
(D) in the eastern United States will typically devastate an area 100 times greater than will a quake of
comparable magnitude occurring in the West
(E) that occurs in the eastern United States will typically devastate 100 times more area than if it occurred
with comparable magnitude in the West

175. Two new studies indicate that many people become obese more due to the fact that their bodies burn
calories too slowly than overeating.

(A) due to the fact that their bodies burn calories too slowly than overeating
(B) due to their bodies burning calories too slowly than to eating too much
(C) because their bodies bum calories too slowly than that they are overeaters
(D) because their bodies bum calories too slowly than because they eat too much
(E) because of their bodies burning calories too slowly than because of their eating too much

186. Judge Bonham denied a motion to allow members of the jury to go home at the end of each day instead of
to confine them to a hotel.

(A) to allow members of the jury to go home at the end of each day instead of to confine them to
(B) that would have allowed members of the jury to go home at the end of each day instead of confined to
(C) under which members of the jury are allowed to go home at the end of each day instead of confining
them in
(D) that would allow members of the jury to go home at the end of each day rather than confinement in
(E) to allow members of the jury to go home at the end of each day rather than be confined to

Guys, can any one of you help me to understand these, pleas

and the difference between like,such and as ?

thanks

The Number of : is the Subject which is Singular rest after OF is Just a Middleman... so a ,b gone..
Up to : Unidiomatic : so d, e gone.. Correct form is From X to Y..
left with C..

Scientists have observed large concentrations of heavy-metal deposits in the upper twenty centimeters of Baltic Sea sediments, which are consistent with the growth of industrial activity there.

(A) Baltic Sea sediments, which are consistent with the growth of industrial activity there - 'which' is incorrectly refering to baltic sea sediments
(B) Baltic Sea sediments, where the growth of industrial activity is consistent with these findings - same as A
(C) Baltic Sea sediments, findings consistent with its growth of industrial activity - "its" has no referent
(D) sediments from the Baltic Sea, findings consistent with the growth of industrial activity in the area - correct
(E) sediments from the Baltic Sea, consistent with the growth of industrial activity there - consistent what???

(A) have grown from 48 million to nearly 59 million, an area that is about Colorado's size - 'the number of' is singular and so we need 'has'
(B) have grown from 48 million to nearly 59 million, about the size of Colorado - same as in A
(C) has grown from 48 million to nearly 59 million, an area about the size of Colorado - correct
(D) has grown from 48 million up to nearly 59 million, an area about the size of Colorado's - 'size of Colorado's' is incorrect because it says 'size of colorado's size'
(E) has grown from 48 million up to nearly 59 million, about Colorado's size - 59 million is what???

this one was difficult for me. I had to read and understand from other places. So excuse me if it is not very clear

the correct idioms are

greater X than Y
X greater Than Y
100 times the area of....
100 times the area that.....

Because the Earth's crust is more solid there and thus better able to transmit shock waves, an earthquake of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West.

(A) of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West - "an X devastates an area 100 times greater in X than it does in Y" is not parallel

(B) of a given magnitude will typically devastate 100 times the area if it occurs in the eastern United States instead of the West - "an X of a.....will devastate 100 times the area.....instead of.....is wrong construction. Also 'it' can refer to area, earthquake or crust

(C) will typically devastate 100 times the area in the eastern United States than one of comparable magnitude occurring in the West - "an X will devastate 100 times the area......than......." is wrong construction. Also the sentence is not parallel

(D) in the eastern United States will typically devastate an area 100 times greater than will a quake of comparable magnitude occurring in the West - an X in the US will devastate an area 100 times greater than will a quake occuring in the west - correct

(E) that occurs in the eastern United States will typically devastate 100 times more area than if it occurred with comparable magnitude in the West - not parallel and 'it' can refer to many nouns.

we have to provide a reason for obesity and so because is needed

Two new studies indicate that many people become obese more due to the fact that their bodies burn calories too slowly than overeating.

(A) due to the fact that their bodies burn calories too slowly than overeating - not parallel
(B) due to their bodies burning calories too slowly than to eating too much - not parallel
(C) because their bodies burn calories too slowly than that they are overeaters - not parallel
(D) because their bodies burn calories too slowly than because they eat too much - parallel. correct
(E) because of their bodies burning calories too slowly than because of their eating too much - wordy and awkward

'rather than' is preferred over 'instead of'

Judge Bonham denied a motion to allow members of the jury to go home at the end of each day instead of to confine them to a hotel.

(A) to allow members of the jury to go home at the end of each day instead of to confine them to
(B) that would have allowed members of the jury to go home at the end of each day instead of confined to
(C) under which members of the jury are allowed to go home at the end of each day instead of confining
them in
(D) that would allow members of the jury to go home at the end of each day rather than confinement in - 'confinement is incorrect here.
(E) to allow members of the jury to go home at the end of each day rather than be confined to - correct
