Read the following sentences and re-arrange them accordingly

(Q) went to him
(R) of all professions
(S) for medicine and treatment

RQPS

The correct answer is option 1. RQPS.

People of all professions went to him at his dispensary for medicine and treatment.

Let us break down the arrangement "QRPS":

Q: This starts the sentence by introducing the subject - "People."

R: Following "Q," this segment specifies a characteristic of the people - "of all professions."

P: Next, "P" describes the location or setting where the people went - "at his dispensary."

S: Finally, "S" concludes the sentence by stating the purpose of why the people went to the dispensary - "for medicine and treatment."

So, when arranged as "QRPS," the sentence flows logically from introducing the people and their diverse backgrounds to describing the location they visited and the purpose of their visit.
