The correct answer is: A. PQSR
The first sentence, S1, introduces the topic of corruption in the country. The second sentence, P, states that there is hardly anything that the government can do about it. The third sentence, Q, provides evidence to support this claim by mentioning graft and other malpractices. The fourth sentence, R, explains why corruption is so difficult to control. The fifth sentence, S, provides an example of the government’s efforts to combat corruption. The sixth sentence, S6, concludes the paragraph by stating that corruption is a tragedy of great magnitude.
The other options are incorrect because they do not follow the logical order of the sentences. Option B, QSRP, puts the evidence before the claim. Option C, RSQP, puts the explanation before the evidence. Option D, SQRP, puts the example before the explanation.
