Concept:A para jumble is arranged by connecting ideas and using pronoun/reference clues to form one clear paragraph.
Explanation:S1 states that the Japanese empire was considered rich.
So, S must follow S1 because the phrase "This was because" gives the reason for this richness.
Q follows S as it adds that, over time, the silk from Nishijin became world-famous, continuing the description of Japan's economic status.
P comes next because it starts with "However" and presents the problem: paying for the imported luxury goods with gold and silver put a strain on the economy and caused the Tokugawa to restrict exports of precious metals.
R follows P because the pronoun "They" in R refers to the Tokugawa rulers already mentioned in P.
R also mentions their steps to develop the silk industry in Nishijin to reduce imports.
Finally, S6 connects well to R because it speaks about "other developments" showing the economy growing in fresh ways.
Answer:The correct sequence is S1, S, Q, P, R, S6, which matches option C (SQPR).
