Origami is capable of turning a simple sheet of paper

A. To introduce a discussion on the most critical aspect of the technique that dictates the transformation of origami from paper to potentially real structures

Incorrect: Irrelevant

Firstly, the critical aspect being referred to is that of kirigami and not origami. Secondly, this feature is stated as an important aspect but not the “most” important aspect. Lastly, the author does not introduce a new discussion but instead carries on from the previous paragraph’s discussion of the features of kirigami.

B. To highlight the scope of kirigami across various applications

Incorrect: Irrelevant

There is no discussion in this paragraph on the scope of kirigami on various applications. In fact, it is the third paragraph in which the author briefly analyses the scope of the technique with respect to one application- nanotechnology.

C. To suggest how maintaining a quality of the technique of kirigami is key to its application to various materials

Incorrect: Partial scope

The author does talk about this quality but this mention forms part of a bigger discussion of the features of the technique; for instance, the author also talks about the benefit of the hexagonal lattice vi-a-vis some other shapes.

D. To evaluate some key features of the technique of kirigami

Correct

This choice rightly captures the essence of the second paragraph and matches our pre-thinking.

E. To analyze what makes kirigami a successful technique for fabricating materials

Incorrect: Irrelevant

The talk about fabrication happens in the final paragraph. In the second paragraph, the author mostly talks about maintaining proportions.


A. Origami as an art form is less flexible than kirigami, making it less relevant for building nanostructures.

Incorrect: Out Of Scope

Nowhere in the passage does the author compare kirigami and origami.

B. In nanoscale projects, certain building materials can be tricky to work with as they are relatively rigid for the purpose of shaping.

Correct

This statement can be derived from the final sentence of the passage. The author says that:

Kirigami is particularly attractive for nanoscale applications, where the simplest, most space-efficient shapes are necessary, and self-folding materials would circumvent some of the fabrication challenges inherent in working with other materials at such small scales.

Since the self-folding materials would avoid the fabrication/shaping problems that can occur when working with other materials at such small scales, it can be deduced that these other materials are more rigid compared to the self-folding ones.

C. It is very difficult to fill in spaces in structures formed of patterns other than the hexagonal lattice.

Incorrect: Out Of Scope

The passage states that it is easier to fill spaces with a hexagonal lattice, presenting a comparison between this shape and others. It makes a relative/comparative statement; however, the choice makes an absolute statement.

D. An important quality for transforming paper designs to materials that could be used in real-world structures is that the shape of the hexagonal grid should not change.

Incorrect: Out Of Scope

The author states that the important quality of the technique is that the resulting proportions of the shape, and the not the shape itself, are kept intact.

E. The type of material to be used changes drastically with the change in the ultimate application.

Incorrect: Out Of Scope

The author states that the relevant material can be selected keeping in mind the ultimate application. The extent of the change in material is neither stated nor suggested.


A. discussing the advantages and disadvantages of a technique

Incorrect: Partial Scope

The passage never delves in to discussing the disadvantages of the technique created from kirigami.

B. explaining how a technique is more than just a superficial art form

Incorrect: Inconsistent

There is no basis to conclude that kirigami, without its further application in the field of developing structure, is a “superficial” art form. Also, the entire passage is written from the point of view of appreciating the rules and features of kirigami and how these rules can be applied to building structures with almost any material. So, if anything, the rules underlying kirigami are actually appreciated.

C. highlighting the relevance of a particular pattern in the application of a technique to building structures

Incorrect: Partial Scope

The author does highlight the relevance of the hexagonal lattice but that is only a part of the entire passage. The whole passage does not concentrate on hexagonal lattice.

D. discussing revolutionary techniques for building 3-D structures

Incorrect: Irrelevant

The whole passage revolves only around one technique- the one developed from kirigami.

E. discussing the potential of a technique for building varied physical structures

Correct

This answer choice is on the same lines as the one we came up with in our pre-thinking, and summary and main point section.
