I want to know the answer to the following question:
Which of two Voskhod 2's occupants was almost killed?
All the background I'm provided with is that "He succeeded in safely re-entering the ship, but he and Belyayev faced further challenges when the spacecraft's atmospheric controls flooded the cabin with 45% pure oxygen, which had to be lowered to acceptable levels before re-entry.". Is that enough to answer the question?
Answer: no
