Task: Question Generation
Input (English): Passage: Spencer Armacost is an astronaut working for NASA, and his wife Jillian is a second-grade elementary school teacher. While he and Alex Streck are walking in space on a mission there is an explosion that knocks out their communication with the command center.
They land but when their spouses arrive to see them they are in the hospital; both asleep until they recover. Armacost eventually wakes up without problems, but Streck has a medical emergency requiring him to have an electrical cardioversion. Neither speak about the in-flight emergency. Armacost accepts a position with a New York-based company, McClaren. At a farewell party, Streck's aggressive behavior catches Jillian's attention before he suddenly dies from what NASA attributes to a stroke. At the Streck house Natalie Streck electrocutes herself in the bath with a radio. 
In New York at a party, Jillian asks Spencer to tell her about the space walk incident. He answers while he starts to make love to her. At home he makes aggressive love to her. In the background is a crackling radio noise. She finds out she is pregnant, and at an ultrasound discovers she is having twins. She tells the doctor that earlier in her life, after her parents died, she sought psychiatric care because she started to see her loved ones dead, including herself.
Output (English): What are the full names of the people who won't talk about the in-flight emergency?
