Rearrange the parts to make a meaningful sentence.

P. who lives in a village without a post office

Q. the letter that my father

R. had posted a month earlier

S. finally reached my uncle,

Explanation

1. 01

   Q names the subject, "the letter", and begins a clause about it: "that my father". R finishes that clause: "had posted a month earlier".

2. 02

   Then the letter's own verb comes: S "finally reached my uncle". P begins with "who", which describes the uncle, so it follows him.

3. 03

   So the order is QRSP: "The letter that my father had posted a month earlier finally reached my uncle, who lives in a village without a post office."
