Read the following statements and answer the question that follows:

  1. But its most advanced formulation is called superstring theory, which even predicts the precise number of dimensions: ten.
  2. However, the theory has already swept across the major physics research laboratories of the world and has irrevocably altered the scientific landscape of modern physics, generating a staggering number of research papers in the scientific literature (over 5,000 by one count).
  3. Scientifically, the hyperspace theory goes by the names of Kaluza-Klein theory and supergravity.
  4. The usual three dimensions of space (length, width, and breadth) and one of time are now extended by six more spatial dimensions.
  5. We caution that the theory of hyperspace has not yet been experimentally confirmed and would, in fact, be exceedingly difficult to prove in the laboratory.

Rank the above five statements so as to make it a logical sequence:

  1. A.

    3, 1, 4, 5, 2

  2. B.

    3, 4, 1, 5, 2

  3. C.

    5, 1, 4, 3, 2

  4. D.

    3, 1, 4, 2, 5

  5. E.

    2, 5, 3, 1, 4

Answer

A

Explanation

Statement 3 introduces hyperspace theory. Statement 1 builds on 3 ('its most advanced formulation... ten dimensions'). Statement 4 explains these ten dimensions. Statement 5 introduces a caveat ('has not yet been experimentally confirmed'). Statement 2 contrasts this caveat ('However, the theory has already swept...'). Thus, 3-1-4-5-2 is logical.
