The question below consists of a set of labelled sentences. Out of the four options given, select the most logical order of the sentences to form a coherent paragraph. P: In February 2010 the medical council of India announced a major change in the regulation governing the establishment of medical colleges. Q: The new regulation also carried the following warning: "permission shall be withdrawn if the colleges resort to commercialization".  R: With this change, corporate entities were permitted to open medical colleges. S: Since the regulation does not elaborate on what constitutes "resorting to commercialization", this will probably be a matter left to the discretion of the government.
