Concept:This question tests the ability to arrange sentences in a logical sequence to form a coherent paragraph about the effects of inflation.
Explanation:Sentence 1 introduces inflation affecting both consumers and businesses.
Q is the first logical follow-up because it explains the direct impact on individuals: rising prices reduce purchasing power.
P comes next as it describes how businesses then struggle to maintain profit margins due to the same inflation.
R follows logically, introducing the role of governments in using monetary policy to manage inflation.
S is placed last before sentence 6 because it talks about long-term investment uncertainty, which leads naturally into the conclusion about the importance of managing inflation.
Thus the correct sequence is Q, P, R, S.
Answer:Option A (QPRS)
