Correct Answer: QPSR

Solution : The correct choice is the fourth option.

The sentence starts with a general statement about physical movement's importance (Q), then contrasts by mentioning that not all learning requires it (P), specifies what might not be required (S), and ends by indicating who is involved (R).

To understand the logic for arranging the sentence parts "While physical movement (QPSR)", let's examine each part:

Q. is important for children, all learning**: This segment seems to continue from a statement about something that is important for children. It suggests a contrast or a condition, which is typical for a sentence beginning with "While".

P. activities may not require physical**: This part likely follows a mention of what is important for children, suggesting a contrast or exception.

S. movement and facial expressions on**: This fragment seems incomplete and needs a preceding part to make sense. It's probably talking about the type of movement or expression.

R. the part of teachers and students**: This part clearly refers to the subjects (teachers and students) and should follow a mention of an action or a characteristic related to them.

So, the logic of arrangement:

- Start with "While" (an introductory clause setting the stage for a contrast).

- Follow with Q, as it mentions what is important for children and sets up the contrast.

- Then P, as it provides the contrasting point (what activities may or may not require).

- S comes next, as it elaborates on the type of physical activity being discussed.

- Finally, R, as it specifies who is involved in these activities (teachers and students).

Therefore, the arrangement QPSR forms a coherent sentence: "While physical movement is important for children, all learning activities may not require physical movement and facial expressions on the part of teachers and students."
