Question

several other kids in dark, skater clothes were slipping up and down, and halftime hovered for them. i watched as one girl twirled in midair, her feet stuck to the skateboard like theyd been glued on. it looked like magic. sweat poured down my sides.
\want to try?\ justine nudged her skateboard toward me. i shook my head, but she just slid it closer. i felt the other kids watching us.
cautiously, i got on the board—and immediately tipped. justine caught me before i fell. \balance your weight evenly on both feet,\ she said, steadying me.
i tried not to think of my chipped teeth as i pushed off. for an instant, i rolled smoothly along the pavement. and then i fell, my arms windmilling. justines friends laughed.
how does tiana most likely feel when she sees the girl twirl in midair?
she is excited about learning new skateboarding tricks like the one the girl is doing.
she is jealous because the girl gets to do flashier tricks than the one she will try.
she feels anxious about having to try skateboarding herself.
she is worried that the girl is going to hurt herself.

Explanation:

The text states Tiana sweated while watching the girl skate, hesitated when offered a board, and felt nervous when trying. When she saw the girl twirl, she found it "like magic" but showed physical signs of anxiety (sweating) before being asked to try. This matches the anxious feeling about having to skate herself. The other options don't fit: she didn't show excitement to learn the trick, no jealousy is mentioned, and no worry for the girl's safety is stated.

Answer:

She feels anxious about having to try skateboarding herself.
