You will be given a definition of a task first, then some input of the task.
You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.

Paragraph- Sent 1: Suddenly, Amy screamed.
Sent 2: I whirled around and threw up my arm just in time to knock Dvorov away.
Sent 3: His eyes were glowing red, and he had bared a set of fangs that could probably take my hand off.
Sent 4: The dancers near us tried to clear some space.
Sent 5: He shot back up, hardly touching the ground, and I kicked him back.
Sent 6: He jumped at my arm while I was still off-balance, and I felt the surge of adrenaline that comes right when your body realizes that it's too late to save itself.
Sent 7: A heavy thing hit my arm with a thump and knocked me back against someone with rough paws who held me up.
Sent 8: On the floor was Dvorov's head, separated from his body by several feet and a growing puddle of dark blood.
Sent 9: Nepthys stood over him with a blue sword in his hand.
Sent 10: It flashed in the strobe where it wasn't streaked with Dvorov's blood.
Sent 11: "He wasn't the only one with a secret or two," he said by way of explanation.
Sent 12: "You spotted our boy, didn't you?
Sent 13: I bet his hide-out is nearby, too.
Sent 14: Let's hurry." He wiped off the sword and sheathed it in a scabbard now belted to his hip.
Sent 15: The crowd parted for us.
Sent 16: The vampire glanced up when he saw the crowd split and his eyes flashed when he noticed us.
Sent 17: In a blink of the strobe light, he was on his feet and dashing from the room.
Sent 18: "Come on!" shouted Nepthys.
Sent 19: We chased after him, Amy keeping up valiantly behind us.
Sent 20: He bashed up a set of stairs set into the side of the wall, and we chased up after him, heading up a huge staircase that seemed to go up for more stories than the building could have held.
Output:
What made Amy scream?
