Doubt in SC

  Dear All,

Please help me out with the following SC questions:

1. Students in the metropolitan school district lack math skills to such a large degree as to make it difficult to absorb them into a city economy becoming ever more dependent on information-based industries.

(A) lack math skills to such a large degree as to make it difficult to absorb them into a city economy becoming
(B) lack math skills to a large enough degree that they will be difficult to absorb into a city’s economy that becomes
(C) lack of math skills is so large as to be difficult to absorb them into a city’s economy that becomes
(D) are lacking so much in math skills as to be difficult to absorb into a city’s economy becoming
(E) are so lacking in math skills that it will be difficult to absorb them into a city economy becoming

I am confused between option D and E.

2. Studies of the human “sleep-wake cycle” have practical relevance for matters ranging from duty assignments in nuclear submarines and air-traffic control towers to the staff of shifts in 24-hour factories.

(A) to the staff of
(B) to those who staff
(C) to the staffing of
(D) and staffing
(E) and the staff of

3. Sulfur dioxide, a major contributor to acid rain, is an especially serious pollutant because it diminishes the respiratory system’s ability to deal with all other pollutants.

(A) an especially serious pollutant because it diminishes the respiratory system’s ability to deal
(B) an especially serious pollutant because of diminishing the respiratory system’s capability of dealing
(C) an especially serious pollutant because it diminishes the capability of the respiratory system in dealing
(D) a specially serious pollutant because it diminishes the capability of the respiratory system to deal
(E) a specially serious pollutant because of diminishing the respiratory system’s ability to deal

Here, what is the difference between specially and especially? Why can't I choose option D here?

  Hi Rupali,
Here are the solutions to your problems:

1.) E is the correct option. There is nothing called "large degree".
When one talks about ‘degree’ one must understand that the word ‘degree’ refers to a comparative growth or reduction and not physical size (as would be indicated by the use of the word ‘large’), hence large would be the inappropriate adjective to apply to ‘degree’. Thus, options A, B and C are eliminated. Now, in D we have "lacking so much in math skill as to be difficult to absorb", which is wrong because there is a construction "so A that B". Also, here it gives an idea that it is difficult to absorb for someone, which is not the case. Hence, E.

2.) D is the correct option. There is a parallelism error in this. It makes a parallel relation between the name of the work and the staffs, which is wrong according to this sentence. C makes a correct parallel relation between the noun or the name of the work duty assignments and another work staffing.

3.) A is the correct option.
Especially implies that something less good exists, whereas something Specially doesn’t need to be compared against anything. Therefore, here we use especially.
Also, in option D, there is the use of a word Capability rather than ability. Here, the use of capability is wrong because Capability implies unrealized potential, but in this sentence it is not the hidden potential of the respiratory system. Hence, A is correct.
