Given the question: What is the answer for the question: What are the first names of the people the assistant of the operations manager is responsible for? from the following article ?  Teenaged brothers Zach and Gray Mitchell visit Jurassic World, a dinosaur theme park at the original Jurassic Park site on Isla Nublar. Their aunt, Claire Dearing, is the operations manager. Claire assigns her assistant, Zara, as the boys' guide but they soon evade her. Elsewhere on the island, U.S. Navy veteran and ethologist Owen Grady has been training and researching four Velociraptors. Based on the raptors' ability to follow commands, Vic Hoskins, the head of InGen Security, believes the animals can be weaponized, an idea Owen and his assistant Barry strongly oppose. Prior to its opening, Claire and park owner Simon Masrani inspect the park's newest attraction, Indominus rex, a genetically-engineered dinosaur created by geneticist Dr. Henry Wu. Masrani tasks Owen with evaluating the enclosure. Owen warns Claire the Indominus lacks social skills, making it more dangerous and unpredictable. When it appears the Indominus has escaped, Owen and two park workers enter the enclosure. The Indominus, which can camouflage itself and mask its heat signature, suddenly appears. Owen survives the attack, but it kills the other two men before escaping into the island's interior. Owen tells Masrani to have the Indominus killed; to protect his company's investment, Masrani instead dispatches a specialized unit to subdue it with non-lethal weaponry. After most of the unit is wiped out, Claire orders the evacuation of the island's northern sector.
The answer is:
Zach
