What does "to be **borne out**" mean in this context? (From "Little Women")
“I can’t help it; I never saw anyone faint, and I don’t choose to make myself all black and blue, tumbling flat as you do. If I can go down easily, I’ll drop; if I can‘t, I shall fall into a chair and be graceful. I don’t care if Hugo does come at me with a pistol,” returned Amy, who was not gifted with dramatic power, but was chosen because she was small enough **to be borne out shrieking by the villain of the piece.**
“Do it this way: clasp your hands so, and stagger across the room, crying frantically, ‘Roderigo! save me! save me!’” and away went Jo, with a melodramatic scream which was truly thrilling.
Amy followed, but she poked her hands out stiffly before her, and jerked herself along as if she went by machinery, and her “Ow!” was more suggestive of pins being run into her than of fear and anguish. Jo gave a despairing groan, and Meg laughed outright, while Beth let her bread burn as she watched the fun with interest.

What does small enough to be borne out mean?

Answer

The verb "to bear" can mean "to carry."  It's a somewhat literary usage, and it usually describes the act of carrying something heavy or unwieldy (you need two hands to carry it) or something important. For example: "The waiter returned to the table, bearing a tray of dishes."

The past tense of "to bear" is "bore" ("The waiter bore a tray of dishes"), and the past perfect tense is "borne" ("The waiter had borne a tray of dishes").

In this passage, the verb is being used in passive form.  To say that the girl "was small enough to be borne out" means that she was small enough to be carried out (of a room, house, etc.).  She was small enough that a person could physically grab her and carry her out of the room.
