Rearrange the parts to make a meaningful sentence.

P. the room, all the

Q. when the teacher entered

R. and wished her

S. good morning

T. students stood up

Explanation

1. 01

   "When" begins a time clause: Q, then P "the room," and "all the", which needs a noun.

2. 02

   T completes "all the students" and gives their verb, and R adds a second action, which S completes.

3. 03

   So the order is QPTRS: "When the teacher entered the room, all the students stood up and wished her good morning."
