Question

read the text.
i stepped forward and flicked my wrist. the stone skipped across the waters glassy surface three times before sinking, creating beautiful, concentric rings that folded into each other. the sound of sneakers sliding in gravel startled me, and i crossed my arms as i realized that i was being watched.
\kyra, you can skip rocks?\ i turned to see olivia behind me. my face grew hot as i casually dropped the rocks i had been holding.
\yeah, sort of,\ i mumbled. olivia was good at everything she tried. when she wasnt winning track medals, she was starring in the school musical or leading the debate club.
\ive never been able to!\ olivia said helplessly. \it looks so cool, though. i wish i could.\
seeing olivias smiling face, i realized that maybe being able to skip rocks wasnt a worthless talent after all. i leaned down and picked up a rock i had dropped, holding it out for her.
\want to practice?\ i asked. olivia nodded eagerly and joined me at the waters edge. she concentrated, aimed, and threw the rock. it sank immediately with a loud plunk.
\i told you!\ she said, laughing.
\its all in the wrist,\ i said, standing a little straighter and skipping another stone; that one made it to the middle of the pond. we took turns, giggling with joy when one of olivias rocks finally skipped once.
why does kyra most likely drop the rocks when she sees olivia?
kyra despises olivia and does not want to have to skip rocks with her.
kyra is shy and does not like showing off in front of other people.
kyra is embarrassed to be seen doing something as basic as skipping rocks.
