Why am I in the hospital?

When Lucy woke up in the hospital it took her a while to piece together where she was and why she was there.

She remembered that she had had a picnic with her friends on the beach and they had met there at two o'clock. When they were all together, Marta, who was very pretty, saw a cave far away. All of them immediately went into the dark cavern because it had started raining, so they had the picnic in that huge place. When Lucy saw that it was very deep, she wanted to explore it, but she was hungry. Suddenly there was an earthquake and some rocks were fallen and hit Lucy on the head and she became dizzy.

By the time she was groggy, her friends were eating the picnic and Maria realized that Lucy had disappeared. She went rapidly to see where she was and she observed that Manuela was on the floor and around her head there was a pool of blood. Maria quickly phoned the hospital and the ambulance came to take Lucy. And that is why she was in hospital.
