In this task, you're expected to write answers to questions involving multiple references to the same entity. The answer to the question should be unambiguous and a phrase in the paragraph. Most questions can have only one correct answer.

[Q]: Passage: Minnesota has some of the earth's oldest rocks, gneisses that are about 3.6 billion years old (80% as old as the planet). About 2.7 billion years ago, basaltic lava poured out of cracks in the floor of the primordial ocean; the remains of this volcanic rock formed the Canadian Shield in northeast Minnesota. The roots of these volcanic mountains and the action of Precambrian seas formed the Iron Range of northern Minnesota. Following a period of volcanism 1.1 billion years ago, Minnesota's geological activity has been more subdued, with no volcanism or mountain formation, but with repeated incursions of the sea, which left behind multiple strata of sedimentary rock.In more recent times, massive ice sheets at least one kilometer thick ravaged the state's landscape and sculpted its terrain. The Wisconsin glaciation left 12,000 years ago. These glaciers covered all of Minnesota except the far southeast, an area characterized by steep hills and streams that cut into the bedrock. This area is known as the Driftless Zone for its absence of glacial drift. Much of the remainder of the state outside the northeast has 50 feet (15 m) or more of glacial till left behind as the last glaciers retreated. Gigantic Lake Agassiz formed in the northwest 13,000 years ago. Its bed created the fertile Red River valley, and its outflow, glacial River Warren, carved the valley of the Minnesota River and the Upper Mississippi downstream from Fort Snelling. Minnesota is geologically quiet today; it experiences earthquakes infrequently, and most of them are minor. 
Question: What is the name of the area in Minnesota was not covered by massive ice sheets?
[A]: the Driftless Zone.


[Q]: Passage: A paleontologist named Zack takes his nephew Ricky and niece Jade on a fossil hunt. While alone, Ricky is met by a talking raven, who turns into an Alexornis named Alex. He tells him of a story set in the Cretaceous period 70 million years ago. Patchi is the smallest in a litter of Pachyrhinosaurus hatchlings, and is often bullied by his older brother Scowler. Their father Bulldust is the leader of the Pachyrhinosaurus herd. Alex, who is Patchi's mentor, tries to help Patchi impress a female Pachyrhinosaurus named Juniper, but her herd migrates south without him.
Bulldust moves his herd south as well, but when they try to pass through a forest, they are forced to flee when a storm strikes and a fire erupts. Taking advantage of the chaos, a pack of Gorgosaurus attacks the scattered herd. They kill the rest of Patchi and Scowler's family while their leader Gorgon fights and kills Bulldust. Afterwards, Patchi's herd (now led by Bulldust's rival Major) combines with Juniper's as they continue their migration. There, Gorgon's pack attacks them again. In the ensuing chaos, Patchi, Scowler, and Juniper fall into a river and are swept downstream to the ocean, with Alex following them from above. At a beach, Scowler follows a herd of Edmontosaurus to find food, callously leaving Patchi and Juniper behind. The two make their way through a forest and eventually are able to find their herd and Scowler. 
Question: What are the names of the two Pachyrhinosausus that make their way through the forest to find their heard?
[A]: Patchi.


[Q]: Passage: The remaining vampire covens are on the verge of annihilation by the Lycans. Both species are searching for Selene: the vampires seek justice for the death of Viktor, while the Lycans, led by Marius, intend to use her to locate Eve, whose blood holds the key to building an army of vampire-werewolf hybrids.
Semira, a council member of the Eastern Coven, tells Thomas she wants Selene to be granted clemency and to train the coven's neophyte Death Dealers. She asks Thomas to plead Selene's case before the full council; the plea is successful and the council reluctantly agrees to a pardon in exchange for Selene's help. Selene arrives with David. Semira has Varga, her ally and lover, poison Selene and slaughter the trainees, framing Selene for the atrocity. With Selene in her power, Semira begins draining her blood, which she intends to drink to steal her power. Thomas and David attempt a rescue, but are attacked by Semira and Varga. Thomas is killed, but David and Selene escape.
The pair takes refuge at the Nordic Coven, pursued by Alexia, an Eastern Coven vampire dispatched by Semira. At Var Dohr, the Nordic Coven stronghold, Elder Vidar reveals that David is the son of High Elder Amelia, and thus the legitimate heir to the Eastern Coven.
Meanwhile, Alexia has told Marius, who is secretly her lover, that Selene is going to the Nordic Coven. Marius and his Lycans attack that coven. Selene and David fight alongside the Nordic vampires, who are led by Vidar's daughter Lena. Selene engages Marius in single combat, but he is too powerful in werewolf form, and she is stabbed by Alexia. Marius demands to know Eve's location, but Selene insists she does not know; Alexia confirms this after tasting blood from her sword. Marius sounds the retreat. Selene deliberately slides herself under the now broken ice of the lake, telling herself that this is the 'path'. 
Question: What are the first names of the people who take refuge at the Nordic Coven?
[A]:
David.
