Rearrange the parts to make a meaningful sentence.

P. have helped you

Q. me about the problem

R. fix it

S. if you had told

T. earlier, I could

Explanation

1. 01

   "If" begins the condition: S "if you had told", and "told" needs whom and what: Q.

2. 02

   T says when and ends the condition, then gives the result, "I could", which needs "have" and a past form: P. R finishes it.

3. 03

   So the order is SQTPR: "If you had told me about the problem earlier, I could have helped you fix it."
