Rearrange the parts to make a meaningful sentence.

P. the water level fell

Q. the river until

R. the children were told

S. not to go near

Explanation

1. 01

   R is the main clause, and "told" is followed by "not to" and a verb: S "not to go near".

2. 02

   "Near" needs a place: Q "the river until", and "until" needs a clause: P.

3. 03

   So the order is RSQP: "The children were told not to go near the river until the water level fell."
