Read two events from a story about a girl on a quest to find a mythical creature: Helena crept slowly along the rocky ledge. The ground was hundreds of feet below her, but she kept going forward. Suddenly, there was a terrible screech. She looked up to see a giant, sharp-toothed bird diving toward her. Without pausing to think, she threw her walking stick toward the enormous bird and jumped forward to wedge herself into a little crevice in the cliff face. The bird screeched again and dove toward her; she began to throw rocks at it until it finally gave up and flew away.

She was lost in the cave! A wave of panic rushed through Helena, but she managed to hold herself back from running. Desperately, she tried to light her torch again, but in the darkness she couldn’t manage to get it alight. Shaking with fear, she reached out until she could touch the wall and slowly crept along the tunnel. It seemed an eternity, but finally Helena saw a glimpse of light ahead.

How are Helena’s responses to the two events similar?
A. She has a feeling of panic.
B. She fights off a screeching bird.
C. She shows that she is determined.
