"So, what do we do?" Jess asked.
"We can't just shoo the animals out, but we should be able to manipulate them into moving, using their own sounds." Sorkin explained.
"Cool." Jess said.
"These speakers on the west side of the pen can be set to play a Parasaur food call that will attract the hungry dinos. The speakers on the east control the mating sounds that will attract the more...ah...amorous dinosaur."
"What about that big set of speakers in the middle of the pen?" Jess asked.
"Ah, those emit the danger call." Sorkin explained. "The Parasaurs will instinctively move from it!"
"So, basically we can herd the dinosaurs out of this pen using the speakers and their sounds! How do I turn on the speakers?" Jess asked.
"I'll have to tell your dad to do it when we're ready." Sorkin said. Jess pressed the upper-right button on the control panel.
"Dr. Harding..." Sorkin said.
"Yeah?" Gerry said.
"Turn on the east mating speakers."
Gerry flipped a switch.
A loud gravelly bellow erupted from the center speaker.
A trio of Parasaurolophus looked up towards the speaker. They then walked over to their other companion. Not sensing any danger they walked back to where they were and continued grazing.
"How come that one never moved?" Jess asked, pointing to the look-out.
"That one stands guard to make sure all the others are safe." Sorkin explained.
"Even when there's a danger call?" Jess asked.
"The look out's the one that makes the danger call." Sorkin said. "When there are predators around, she'll stand her ground, drawing attention away from the other dinos."
Jess then pressed the lower right button on the control panel.
"Dr. Harding..." Sorkin said.
"Yeah?"
"I need you to activate the east side speakers, please." Sorkin said.
"East side...okay!" Gerry said, flipping another switch.
This time, a loud, groaning sound played from a speaker.
The Parasaurolophus near it emitted a guttural groan.
"Do you think they'll really turn this place into a nature preserve after this?" Jess asked Sorkin.
"Like Mr. Yoder said?" Sorkin replied. "That guy was lying through his teeth regarding the board...but it did give me a thought. This is a huge setback for InGen. Maybe Hammond's role as CEO isn't as safe as he thinks."
Jess then pressed another button on the control panel.
"Dr. Harding..." Sorkin said.
"Yeah?"
"West side speakers, please!"
Gerry flipped another switch. The speaker played a shrill, whooping bellow. Two of the Parasaurolophus walked away from the speaker.
"So, I heard you were, like, a big protester or something, like, twenty years ago."
"Where'd ya hear that?" Sorkin asked.
"From Yoder." Jess explained.
"The tens were a tumultuous time...I fought for what I believed in. And sometimes it gets ya arrested."
"You were arrested?" Jess asked incredulously. "And you still got a job as a, you know, scientist?"
"Paleo-revivificationist." Sorkin corrected. "And yes. Youth is the time to be reckless and test your boundaries. It's how you learn what's important to you."
Jess pressed the last button on the control panel.
"Dr. Harding..." Sorkin said.
"Yeah?"
"East side speakers again!"
Gerry flipped the switch again. The loud, groaning sound repeated.
The fourth Parasaurolophus walked away from the speaker.
"So...what happened to your assistant?" Jess asked.
"Let's not talk about that, right now." Sorkin said.
"Well, did you work with him long?" Jess asked.
"It doesn't matter..." Sorkin said.
"Oh." Jess said quietly.
"Listen, he was a wonderful young man...and I am sad, I really am." Sorkin said. "But if I let that stop my work, then all these animals will die too...trapped behind the walls that we built. You understand?"
Jess nodded her head.
"Dr. Harding..."
"Yeah?"
"Activate the "danger" speakers!" Sorkin said.
Gerry played the loud, gravelly belllow again. All four of the Parasaurolophus raised their heads, bellowing in response. The group began walking through the open paddock.
"That's it! They're out!" Jess said excitedly.
"Good job, Jess!" Sorkin said.
"Finally! Go forth and multiply!" Jess said, amusingly.
"You're pretty good at this!" Sorkin said. "Maybe you'll be a behavioral scientist someday!"
"Maybe I will!"
