(C) and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids
(D) and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive
(E) and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

I think it shud be 'e' as it says...X (Acid rain and snow) result from the chemical reactions between Y (industrial emissions of sulfur dioxide and nitrogen oxides) and Z (atmospheric water vapor) to produce highly corrosive sulfuric and nitric acids.........

Lemme know the ans....

I think "e" is wrong as acid rain result from the reactions between Y and Z to produce... sounds incorrect.
It should be "...which produce..."
out of 5 options here, "d" may be the closest.

Hi guys,

can anyone help me out to understand the difference in the choices

Ques 1. Within 20 years it will probably be possible to identify the genetic susceptibility an individual may have toward any particular disease. Eventually, effective strategies will be discovered to counteract each such susceptibility. Once these effective strategies are found, therefore, the people who follow them will never get sick.
The argument above is based on which of the following assumptions?
(A) For every disease there is only one strategy that can prevent its occurrence.
(B) In the future, genetics will be the only medical specialty of any importance.
(C) All human sicknesses are in part the result of individuals’ genetic susceptibilities.
(D) All humans are genetically susceptible to some diseases.
(E) People will follow medical advice when they are convinced that it is effective

Well the confusion is between choices 'c' & 'd'.......


Ques 2. Most employees in the computer industry move from company to company, changing jobs several times in their careers. However, Summit Computers is known throughout the industry for retaining its employees. Summit credits its success in retaining employees to its informal, nonhierarchical work environment.
Which of the following, if true, most strongly supports Summit’s explanation of its success in retaining employees?
(A) Some people employed in the computer industry change jobs if they become bored with their current projects.
(B) A hierarchical work environment hinders the cooperative exchange of ideas that computer industry employees consider necessary for their work.
(C) Many of Summit’s senior employees had previously worked at only one other computer company.
(D) In a nonhierarchical work environment, people avoid behavior that might threaten group harmony and thus avoid discussing with their colleagues any dissatisfaction they might have with their jobs.
(E) The cost of living near Summit is relatively low compared to areas in which some
other computer companies are located

between 'b' & 'd'


Ques 3. Although parapsychology is often considered a pseudoscience, it is in fact a genuine scientific enterprise, for it uses scientific methods such as controlled experiments and statistical tests of clearly stated hypotheses to examine the questions it raises.
The conclusion above is properly drawn if which of the following is assumed?
(A) If a field of study can conclusively answer the questions it raises, then it is a genuine science.
(B) Since parapsychology uses scientific methods, it will produce credible results.
(C) Any enterprise that does not use controlled experiments and statistical tests is not genuine science.
(D) Any field of study that employs scientific methods is a genuine scientific enterprise.
(E) Since parapsychology raises clearly statable questions, they can be tested in controlled experiments.

Between 'c' & 'd'.....

Ques 4.
For a trade embargo against a particular country to succeed, a high degree of both international accord and ability to prevent goods from entering or leaving that country must be sustained. A total blockade of Patria’s ports is necessary to an embargo, but such an action would be likely to cause international discord over the embargo.
The claims above, if true, most strongly support which of the following conclusions?
(A) The balance of opinion is likely to favor Patria in the event of a blockade.
(B) As long as international opinion is unanimously against Patria, a trade embargo is likely to succeed.
(C) A naval blockade of Patria’s ports would ensure that no goods enter or leave Patria.
(D) Any trade embargo against Patria would be likely to fail at some time
(E) For a blockade of Patria’s ports to be successful, international opinion must be unanimous.

This one I did not get it right.....

In his work, George Santayana is more reminiscent of Plato's poetic narratives and David Thoreau's obsessive detailing than Bertrand Russel's scientific precisions.

(A) In his work, George Santayana is more reminiscent of
(B) George Santayana writes more like
(C) George Santayana reminds one more of
(D) George Santayana's work is more reminiscent of
(E) George Santayana's work more resembles that of

My answer is (D), but they have mentioned (E) as correct reasoning that "resemble" is better usage than reminiscent for literary comparisons.
Is there any such thing??

Also, I think (E) is wrong because of "resembles that of". just "resembles of" is correct.

D looks better no doubt.
"resembles that of" sounds wrong.just "resembles" would have been ok.
never heard anything like "reminiscent" can't be used for literary comparisons.
the 2 words basically change the whole meaning of the sentence.
reminiscent implies that the works remind us of other works.
resembles implies that the works are similar in style etc.
They are not quite the same thing.

It says that 1 is incorrect because it is a misplaced modiifier... My understanding is that ..[start]In contrast to smaller apartment buildings[end] is a modifier of the sentence after the comma and [start]that contain fewer than four residential units[end] is a modifier of [start]Incontrast to smaller apartment buildings[end]....

please correct me if I am wrong... if that is the case I agree that this is a case of misplaced modifier

2) Excluding those apartment buildings that have fewer than four residential units in them, each room within any residential complex must be equipped with a sprinkler system

Now here... [start]that have fewer than four residential units in them[end] is it a modifier of [start]Excluding those apartment buildings[end]....

is the first sentence before comma a phrase or a clause... like the first sentence isnt this also a case of misplaced modifier since we are talkin of apartmnet buildings and after comma it starts off with a room...

could somebdy please reply to this???

the more I see 2, the more I feel convinced that it is wrong, since the portion before 2 lacks a verb and therfore is a phrase... since after phrases the sentence should begin with the subject... I think that this is wrong
