P. the lights, locked

Q. the door and went

R. she was very tired

S. she turned off

T. to bed early because

Explanation

1. 01

   S has the subject and the first action, which needs an object: P "the lights,", then "locked", the second action.

2. 02

   "Locked" needs an object: Q "the door", then "and went", the third. T says where and brings "because", and R gives the reason.

3. 03

   So the order is SPQTR: "She turned off the lights, locked the door and went to bed early because she was very tired."
