The correct answer is: A. PRQS
The sentence is about a policeman who cannot afford to abide by the strict letters of the law if he has to do well. The correct sequence of the words is:
- A policeman (P)
- cannot afford (Q)
- to abide (R)
- by the strict letters of the law (S)
If we rearrange the words in any other order, the sentence will not make sense. For example, if we rearrange the words in the order QSPR, the sentence would read:
- If he has to do well (Q), a policeman (P) cannot afford (S) to abide (R) by the strict letters of the law.
This sentence does not make sense because it is not clear who “he” is. It is also not clear what “if he has to do well” means.
If we rearrange the words in the order RQPS, the sentence would read:
- A policeman (P) cannot afford (Q) by the strict letters of the law (R) to abide (S).
This sentence does not make sense because it is not clear what “by the strict letters of the law” means.
If we rearrange the words in the order SPRQ, the sentence would read:
- To abide (R) by the strict letters of the law (S), a policeman (P) cannot afford (Q).
This sentence does not make sense because it is not clear what “to abide by the strict letters of the law” means.
Therefore, the correct sequence of the words is: A. PRQS.
