Rearrange the parts of the sentence in correct order.One of the majorP: crises facing theQ: country is theR: looming water shortage

The correct sequence is PQR.The opening phrase "One of the major" requires a plural noun to complete the subject structure. Part P begins with "crises" (plural of crisis), so P follows the opening phrase seamlessly ("One of the major crises facing the...").Part Q provides the noun complement for the phrase ("country is the...").Part R completes the sentence by identifying what the crisis is ("looming water shortage").Thus, the complete sentence reads: "One of the major crises facing the country is the looming water shortage."
