Question: What does the dash do in this paragraph: When I touched down in Korea, I was shocked to find the place that I thought I knew so intimately-the place I was supposed to hail from-was so foreign. Gray skyscrapers towered over the paved streets. Neon storefronts blinked advertisements for cell phones and fried chicken. My "kinsmen"-bedecked in suits and heels-jostled past me without a word, let alone greeting.
