He and his brother Edik were lost.
Kostia and Edik were loading their sledge with firewood.
Kostia and Edik were ice fishing at the time.
He and his brother were hunting.
Why could Kostia "hardly believe his eyes" when looking at the creature by the river?
Kostia wasn't interested in the creature by the river because he needed to get back home with the firewood.
Kostia realized it was an injured reindeer that needed his help.
It was snowing which made it difficult for Kostia to see anything in front of him.
He was startled and shocked to see the animal had a trunk like an elephant instead of antlers like a reindeer.
How did Kostia and Edik's father, Yuri, feel about their discovery?
Yuri was excited for the fame and money that would come with reporting the discovery.
Yuri was so nervous that he decided it would be best to NOT report the sighting of the unusual creature.
Yuri was nervous and troubled about what to do. However, he thought about other people who were able to transform a bad omen into good fortune by sharing the discovery with others. He decided he would do the same to bring good luck upon his family.
Yuri wanted to report the discovery, but he was too far away from the nearest village to be able to send out his message. So, he decided to keep the discovery for him and his family.

Why did the author bring up the amphicyonids, an extinct species from 15 million years ago?
The author states that amphicyonids are also closely related to the mammoth and elephant.
The author describes how we are able to learn more about the amphicyonids by studying bears today because they are also extremely similar.
The author wanted to let readers know that we aren't always able to learn about extinct species if there is nothing alive today that is similar enough to it. That is why not as much is known about the amphicyonids.
The author is describing another species that scientists were able to learn a lot about because Dr. Fisher discovered the full body of an amphicyonid when he was younger.
Scientists were able to conclude that woolly mammoths acted a lot like:
reindeer
bears
elephants
caribou

Scientists still do not know for a fact that woolly mammoths and elephants are similar.
Scientists still do not know why these animals died out.
Scientists still do not know for sure what a woolly mammoth looked like in the flesh.
Scientists still do not know where woolly mammoths lived.
Why is it so important for scientists to discover how the woolly mammoths became extinct?
They are trying to save the elephants that are struggling to survive today.
They want to know how they were able to survive in the tundra for so long.
They want to use this information to figure out how all extinct species died out.
They are trying to determine how Lyuba died since she was only a baby.
