Question:

Read the following statements and answer the questions that follow:

But its most advanced formulation is called superstring theory, which even predicts the precise number of dimensions: ten.
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).
Scientifically, the hyperspace theory goes by the names of Kaluza-Klein theory and supergravity.
The usual three dimensions of space (length, width, and breadth) and one of time are now extended by six more spatial dimensions.
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:

Explanation:

It can be seen that [3] begins the passage by introducing the topic – hyperspace theory. It is then followed by [1], which states that its most advanced formulation is called the superstring theory. [4] comes next as it states the specific details of the dimensions of the superstring theory. Thus, we get the 314 set. Now, [5] states that ‘the theory of hyperspace has not yet been experimentally confirmed’ and [2] follows up by mentioning the other side of the argument that ‘…the theory has already swept across the major physics research laboratories’. Thus, 52 is a pair. This pair can only be placed after the 314 set. Thus we get the sequence 31452.
Hence, the correct answer is option 1.
