Rearrange the parts to make a meaningful sentence.

P. in its first month that

Q. novel sell so many copies

R. the publisher has to reprint it

S. rarely does a debut

Explanation

1. 01

   "Rarely" at the start turns the verb round: S "rarely does a debut", and Q completes the subject, "novel", with a plain verb, "sell".

2. 02

   P says when, and brings "that", the second half of "so many ... that": R.

3. 03

   So the order is SQPR: "Rarely does a debut novel sell so many copies in its first month that the publisher has to reprint it."
