Question

Passage. In this excerpt from Virginia Woolf's Mrs. Dalloway, identify the text that makes unconventional use of metaphors. What an extraordinary habit that was, Clarissa thought; always playing with a knife. Always making one feel, too, frivolous; empty-minded; a mere silly chatterbox, as he used. But I too, she thought, and, taking up her needle, summoned, like a Queen whose guards have fallen asleep and left her unprotected (she had been quite taken aback by this visit—it had upset her) so that any one can stroll in and have a look at her where she lies with the brambles curving over her, summoned to her help the things she did; the things she liked; her husband; Elizabeth; her self, in short, which Peter hardly knew now, all to come about her and beat off the enemy.
"Well, and what’s happened to you?" she said. So before a battle begins, the horses paw the ground; toss their heads; the light shines on their flanks; their necks curve. So Peter Walsh and Clarissa, sitting side by side on the blue sofa, challenged each other. His powers chafed and tossed in him. He assembled from different quarters all sorts of things; praise; his career at Oxford; his marriage, which she knew nothing whatever about; how he had loved; and altogether done his job.

Answer 1

I believe this is the correct answer:
So before a battle begins, the horses paw the ground; toss their heads; the light shines on their flanks; their necks curve. So Peter Walsh and Clarissa, sitting side by side on the blue sofa, challenged each other. 

I would choose that particular paragraphs because the metaphor is slightly unusual there - two kids, Clarissa and Peter Walsh (when they were young) are being compared to horses, which is not really a common occurrence.
