Which line in this excerpt from act 1, scene 1, of Richard 111 is a stage direction? Richard 111 (Duke of Gloucester): . . .

This question is missing the excerpt. I was able to find the complete question online. The excerpt is the following:

RICHARD III (Duke of Gloucester):

. . . And if King Edward be as true and just

As I am subtle, false and treacherous,

This day should Clarence closely me mew'd up,

About a prophecy, which say that 'G'

Of Edward's heirs the murderer shall be.

Dive, thoughts, down to my soul: here

Clarence comes.

(Enter CLARENCE, guarded, and BRAKENBURY)

Brother, good day; what means this armed guard

That waits upon your grace?

GEORGE PLANTAGENET (Duke of Clarence): His majesty

Tendering my person's safety, hath appointed

This conduct to convey me to the Tower.

RICHARD III (Duke of Gloucester): Upon what cause?

The line from the excerpt that is a stage direction is:

(Enter CLARENCE, guarded, and BRAKENBURY).

Explanation:

"Richard III" is a tragic play written by English playwright William Shakespeare which tells the story of how Richard III, king of England, rose to power.

When we write a play, we need to add instructions concerning different aspects such as the actors' positioning on stage or their tone when speaking, the lighting, the sound effects, etc. Those instructions are called stage directions.

In the excerpt we are analyzing here, there is a stage direction indicating when two other characters must come onto the stage, and even indicating that one of them will be accompanied by a guard. Therefore, the stage direction is:

(Enter CLARENCE, guarded, and BRAKENBURY)
