Sentence rearrangement (PQRS): Arrange the parts to complete the courteous enclosure sentence — 'I enclose a postal order … which will cover the price of books and the postage.'

Given data

• Starter: 'I enclose'
• Q: a postal order
• S: which will cover
• R: the price of books
• P: and the postage

Concept/Approach
State the direct object first, then a defining relative clause ('which...') introducing what the postal order covers, followed by coordinated objects.

Step-by-step ordering
Construct: 'I enclose a postal order which will cover the price of books and the postage.' → Q → S → R → P.

Common pitfalls
Putting P before R disrupts the natural 'cover X and Y' rhythm; placing S before Q leaves the relative pronoun without an antecedent.
