The question says, "The enthusiastic practitioners of fractal geometry mentioned in lines 39–40 would be most likely to agree with which one of the following statements?"
(B) says, "Fractal geometry will eventually be able to be used in the same applications for which traditional geometry is now used."
Line 47 is the only place in the passage that mentions traditional geometry. There, the author of the passage describes how the enthusiastic practitioners of fractal geometry believe they'll be able to describe complex natural forms, such as clouds, just as easily as an architect is able to describe a house using the language of traditional geometry. From this, all we can conclude is that the enthusiastic practitioners think that fractal geometry will eventually be used for DIFFERENT, but not the same types of applications that traditional geometry has. In short, (B) is incorrect because it says "the same applications" where instead it would need to read "different" applications if it were to be correct. We can get rid of (B).
(E) says, "Certain complex natural forms exhibit a type of self-similarity like that exhibited by fractals."
These enthusiastic practitioners are discussed in the final paragraph of the passage. Lines 42-48 provide information about what these enthusiasts believe about fractals. They think that they could use the fractals to describe the form of a natural shape, such as a cloud, "as easily and precisely as an architect can describe a house using the language of traditional geometry." In order for them to believe that this is possible, they must believe that natural shapes such as clouds can be broken down into fractals. From this, we know that they would agree that clouds and other natural shapes/forms that the fractals are to describe have to also be self-similar, just like the fractals. Thus, we know that based on the information in the passage we've been given about the enthusiastic practitioners and fractals, (E) is a statement that the practitioners would agree on. This is the correct answer choice.
