Rearrange the parts to make a meaningful sentence.

P. the children found

Q. walking along the beach,

R. been caught in a fishing net

S. a turtle that had

Explanation

1. 01

   Q is an opening phrase with a comma, and it describes the children, so P follows with them and their verb.

2. 02

   Found what? S "a turtle that had", and "had" needs a past form: R "been caught in a fishing net".

3. 03

   So the order is QPSR: "Walking along the beach, the children found a turtle that had been caught in a fishing net."
