Rearrange the parts to make a meaningful sentence.

P. not cleaned after

Q. if the machine is

R. every use, the blades

S. within a month

T. will become blunt

Explanation

1. 01

   "If" begins the condition: Q "if the machine is", and P completes the verb, "not cleaned after", which needs a time: R "every use,".

2. 02

   The comma ends the condition and brings the subject, "the blades". T gives them their verb, and S says how fast.

3. 03

   So the order is QPRTS: "If the machine is not cleaned after every use, the blades will become blunt within a month."
