Existing optical lenses are not thin or flat enough to remove distortions, such as spherical aberration and astigmatism, which prevent the creation of a sharp image. Correction of those distortions requires complex solutions, such as multiple lenses that increase weight and take up space. To overcome these challenges, scientists have developed a new superthin, flat lens. The surface of this lens is patterned with tiny metallic stripes which bend light differently as one moves away from the centre, causing the beam to sharply focus without distorting the images.

In the argument given, the two portions in boldface play which of the following roles?


(A) The first states a problem with existing optical lenses and the second states the solution for this problem that has been developed by scientists

(B) The first is the main conclusion of the argument and the second provides support for this main conclusion

(C) The first is evidence the accuracy of which is questioned later in the argument; the second is a conclusion that the argument supports

(D) The first mentions a problem with existing optical lenses and the second describes the structure of a new type of lens that can solve that problem

(E) The first is a problem associated with one type of optical lens; the second advocates the use of an alternative lens

Is it D ?


(A) The first states a problem with existing optical lenses and the second states the solution for
this problem that has been developed by scientists
"Existing optical lenses are not thin or flat enough" - yes that is the problem
From " To overcome these challenges... " talks about the dvelopement of solution to the above problem. But unfortunately this part of the sentence is not made bold.
The bold part just describes the structure

(B) The first is the main conclusion of the argument and the second provides support for this
main conclusion
Our conclusion is not about existing optical lenses, but about the developed alternative lenses.
(C) The first is evidence the accuracy of which is questioned later in the argument; the second is
a conclusion that the argument supports
No where the argument is questioned. The statements are given as facts.
(D) The first mentions a problem with existing optical lenses and the second describes the
structure of a new type of lens that can solve that problem
"Existing optical lenses are not thin or flat enough" - yes that is the problem
And the second bold part describes the structure of the new lens that can solve the problem

(E) The first is a problem associated with one type of optical lens; the second advocates the use
of an alternative lens
The second one doesn't advocates. It just states a fact- i.e. structure of the alternative.

A is tricky.

The second bold phrase describes the solution in the previous sentence. So the second sentence is not the actual solution.

Right?

D makes more sense.

BTW, even though this is a bolded phrase question, I don't think the it is 700 level. 600-650 IMO.

Yes, absolutely correct. A is a sneaky little option which could make you fall for it, especially if you do not read the other option choices. Beware of easy A answers! Ensure that you read all the options properly.

First bold part - Existing optical lenses are not thin or flat enough to remove distortions - a problem with current optical lenses
Second bold part - The surface of this lens is patterned with tiny metallic stripes which bend light differently as one moves away from the centre - description of a new type of optical lens

(A) The first states a problem with existing optical lenses and the second states the solution for this problem that has been developed by scientists.

The first does state a problem with existing lenses - they are not thin and flat enough to remove distortion.
The solution developed is 'a lens that is super thin and flat'
The second bold statement doesn't 'state' the solution. It tells you 'how' the new lens has solved the problem.

The question is not difficult. But people would fall for the tricky option A especially under pressure on the test and if the argument is made a little more convoluted by adding more junk sentences in the middle.

(A) The first states a problem with existing optical lenses and the second states the solution for this problem that has been developed by scientists

(B) The first is the main conclusion of the argument and the second provides support for this main conclusion

(C) The first is evidence the accuracy of which is questioned later in the argument; the second is a conclusion that the argument supports

(D) The first mentions a problem with existing optical lenses and the second describes the structure of a new type of lens that can solve that problem

(E) The first is a problem associated with one type of optical lens; the second advocates the use of an alternative lens

Official Answer: D
Explanation
The argument basically states that there is a problem associated with currently available optical
lenses and that scientists have developed a new type of lens that can resolve this problem. The
first bold part describes the problem and the second bold part describes the structure of the new
optical lens and how it works.
A. While this option looks good, notice that the second bold part does not actually state the
solution to this problem; it just provides a description of the new optical lens.
B. The first and second bold part are in fact stating opposite things so one cannot be providing
support for the other
C. The accuracy of the first bold part is never at question in the argument. The second is not
really a conclusion
D. The correct answer
E. The first bold part is correct but the second bold part incorrectly uses the term ‘advocate’. The
argument never advocates anything

I'm stuck between A and D.

(A) The first states a problem with existing optical lenses and the second states the solution for this problem that has been developed by scientists
(D) The first mentions a problem with existing optical lenses and the second describes the structure of a new type of lens that can solve that problem

In D : " the second describes the structure of a new type of lens that can solve that problem"
In the passage : "scientists have developed a new superthin"

So the new lens are already finished, and they solve the problem. IMO A but NOT sure

Yesss this is it the BF :cool +1 8-)

B and E are out because the first BF is neither the main conclusion nor a problem associated with one type of lens
C is out because the second BF is not the conclusion of any argument

Well , this is between A or D

First BF: Existing optical lenses are not thin or flat enough to remove distortions

second BF: To overcome these challenges, scientists have developed a new superthin, flat lens. The surface of this lens is patterned with tiny metallic stripes which bend light differently as one moves away from the centre,

(A) The first states a problem with existing optical lenses and the second states the solution for this problem that has been developed by scientists

(D) The first mentions a problem with existing optical lenses and the second describes the structure of a new type of lens that can solve that problem

the argument stated only that the purpose of scientists is to overcome the challenges by creating a new type that can solve the problem and not that they find the utlimate solution hence A is out

We are left with D, which is the correct answer in my opinion :roll:

the new lens are already finished that what you said .. but none has tried them yet , hence we can't assume that they find the SOLUTION ; they just develop a solution that can solve the problem according to the explanation given by the second BF ( the surface of this lens is patterned ..... ) [ it's just the theoretical aspect of the thing, can't conclude that will work for sure ..]

I picked D over A.

The bolded portion talked more about the structure. If the bolded portion included the rest of the sentence, I would have chose A.
The surface of this lens is patterned with tiny metallic stripes which bend light differently as one moves away from the centre, causing the beam to sharply focus without distorting the images.

Good Call.
Let me explain why (A) is not correct (I have given the explanation elsewhere too)

A is a sneaky little option which could make you fall for it, especially if you do not read the other option choices. Beware of easy A answers! Ensure that you read all the options properly.

First bold part - Existing optical lenses are not thin or flat enough to remove distortions - a problem with current optical lenses
Second bold part - The surface of this lens is patterned with tiny metallic stripes which bend light differently as one moves away from the centre - description of a new type of optical lens

(A) The first states a problem with existing optical lenses and the second states the solution for this problem that has been developed by scientists.

The first does state a problem with existing lenses - they are not thin and flat enough to remove distortion.
The solution developed is 'a lens that is super thin and flat'
The second bold statement doesn't 'state' the solution. It tells you 'how' the new lens has solved the problem.

The question is not difficult. But people would fall for the tricky option A especially under pressure on the test and if the argument is made a little more convoluted by adding more junk sentences in the middle.

Yes, so make a promise to yourself - Irrespective of how fatigued you are on exam day during the Verbal section, you will still read all the options and not move on after selecting the first passable option you get.
