Step 1: Read what is being asked.
I find the sentence that quotes the Centre and read the contrast in it.
Step 2: Go back to the passage.
The Centre sentence sets two things against each other: one has decreased and one has increased. I must pick the one that has increased.
Step 3: Test the choice "National Power" (option 1).
This is on the decreased side of the contrast, so it is out.
Step 4: Test the choice "Close Communication ties" (option 2).
The passage does the opposite and doubts better communication, so it is out.
Step 5: Test the choice "Societal wars" (option 3).
This is on the increased side of the contrast, so it is in.
Step 6: Test the choice "Freedom" (option 4).
Freedom is never reported as rising by the Centre, so it is out.
Quick recheck.
I read the chosen line of the passage once more and compare it word by word with the correct choice. The other three choices either change the meaning or bring in something the passage does not say.
Final Answer:
Option 3 is on the increased side.
\[ \boxed{\text{Option 3}} \]
