Q = "They are expected to alleviate the problem of housing." P = "Dwarka is the first among them." R = "It is coming up in the south-west of the capital." S = "It will cater to over one million people when completed." S6 = "Hopefully the housing problem will not be as acute as at present after these sub-cities are built." Between S1 and S6, place P–Q–R–S in a development-focused order aligned with the key. Choose the correct sequence of P–Q–R–S that completes the paragraph.
