S1: Trade and transport have been very significant in the progress of human life.
S6: Thus, trade transport and communication complement each other.
P: For a long time trade and transport moved within the restricted boundaries of space and time.
Q: This has been made possible by the development of a fast and efficient transport and communication system.
R: However, with the developments in the field of science and technology, trade and transport have spread all over the world.
S: The world has, as a consequence, become one big village and distances have become immaterial or, to be more precise, distances seem to have shrunk.

The correct answer is 'Option 2'.

Key Points

• S1: Trade and transport have been very significant in the progress of human life.
  • This sentence introduces the importance of trade and transport.
• P: For a long time trade and transport moved within the restricted boundaries of space and time.
  • This sentence provides a historical context, detailing a past limitation of trade and transport, which logically follows a general statement about their significance.
• R: However, with the developments in the field of science and technology, trade and transport have spread all over the world.
  • The word "However" indicates a contrast to the "restricted boundaries" mentioned in P, introducing the modern reality of widespread trade and transport due to technological advancements. This is a strong transitional link.
• S: The world has, as a consequence, become one big village and distances have become immaterial or, to be more precise, distances seem to have shrunk.
  • The phrase "as a consequence" directly links to the widespread nature of trade and transport described in R, explaining the effect of shrinking distances and a globalized world.
• Q: This has been made possible by the development of a fast and efficient transport and communication system.
  • The pronoun "This" refers to the phenomenon of the world becoming a "big village" and distances shrinking, as described in S. Q then explains the underlying cause: the development of advanced transport and communication systems. The mention of "communication" here is crucial for linking to S6.
• S6: Thus, trade transport and communication complement each other.
  • This concluding sentence synthesizes the elements discussed (trade, transport in S1, P, R, S; and communication introduced in Q), stating their complementary nature, which is a logical summary.
• The sequence P-R-S-Q creates a coherent flow: historical context (P), modern spread (R), consequences of spread (S), and the underlying technological enablers (Q), leading to the final summary (S6).
