Explanation:

Let's break down the sentence fragments:

- Q (those who cannot treat): This introduces the subject, "those who cannot treat..."

- S (others well): This completes the thought started in Q, resulting in "those who cannot treat others well."

- R (should not): This phrase can logically follow the completed thought, introducing a consequence or expectation.

- P (expect others): These words complete the sentence, leading to "expect others" to treat them well.

By rearranging, the sentence becomes: "Those who cannot treat others well should not expect others."

Now, let's analyze the options:

- Option 1: QSRP forms "Those who cannot treat others well should not expect others."

- Option 2: QPRS doesn't logically connect and makes the sentence awkward.

- Option 3: RPQS creates an unclear meaning and disrupts flow.

- Option 4: SRPQ creates a disjointed phrase lacking clarity.

- Option 5: None of these implies none fit, but option 1 does.

In conclusion, the correct option is Option 1: QSRP.
