Passage

Fractal geometry is a mathematical theory devoted to the study of complex shapes called fractals. Although an exact definition of fractals has not been established, fractals commonly exhibit the property of self-similarity: the reiteration of irregular details or patterns at progressively smaller scales so that each part, when magnified, looks basically like and then the process is repeated indefinitely on the segments at each stage of the construction.

Self-similarity is built into the construction process by treating segments at each stage the same way as the original segment was treated. Since the rules for getting from one stage to another are fully explicit and always the same, images of successive stages of the process can be generated by computer. Theoretically, illustrates a major attraction of fractal geometry: simple processes can be responsible for incredibly complex patterns.

A worldwide public has become captivated by fractal geometry after viewing astonishing computer-generated images of fractals; enthusiastic practitioners in the field of fractal geometry consider it a new language for describing complex natural and mathematical forms. They anticipate that fractal geometry's significance will rival that of calculus and expect that proficiency in in mathematics only if it becomes a precise language supporting a system of theorems and proofs.

According to the description in the passage, each one of the following illustrates the concept

Answer choices

  1. Opposite: Matches6% picked this

    Any branch broken off a tree looks like the

    This provides the key idea that "zooming in on a small part looks like the big thing". Zoom in on a branch, and it looks like the tree itself.

  2. Opposite: Matches4% picked this

    Each portion of the intricately patterned frost on a window looks like the pattern

    This provides the key idea that "zooming in on a small part looks like the big thing". Zoom in on a portion of the frost pattern, and it looks like the entire frost pattern.

  3. Opposite: Matches8% picked this

    The pattern of blood vessels in each part of the human body is similar to the pattern of blood

    This provides the key idea that "zooming in on a small part looks like the big thing". Zoom in on a local part of the body, and the pattern of blood vessels will look like the pattern for the entire body.

  4. Correct80% picked this

    The seeds of several subspecies of maple tree resemble one another in shape despite

    Why this is right

    This does not provide the key idea that "zooming in on a small part looks like the big thing". These are all small parts. The seed of this subspecies of maple tree resembles the seed of that subspecies of maple tree, even though one is bigger than the other. While this answer implies that the smaller seed resembles the bigger seed, that's not the same as a Part resembles Whole relationship.

    Skill tested: Application · how this choice captures the passage's function is the move to repeat next time.

  5. Opposite: Matches2% picked this

    The florets composing a cauliflower head resemble the entire

    This provides the key idea that "zooming in on a small part looks like the big thing". Zoom in on a floret within the cauliflower, and it looks like the entire head of cauliflower.
