2. In the teaser opener for this episode, which crew member is making a recording in their log, explaining that "Even if Enterprise makes it past the black hole without being destroyed... it seems likely the crew won't survive."?
From Quiz 2.9 "Singularity"
Answer:
Sub-Commander T'Pol
Due to her Vulcan physiology and logical mind, T'Pol is the only one who seems to have been able to maintain control of her faculties and to stay conscious.
The camera pans over many crew members, all unconscious as she makes her log entry:
"Science officer's log, August 14, 2152. Enterprise remains on course for the trinary system. I've transmitted a distress call, but the nearest Vulcan ship is more than nine days away. By the time they arrive, they may only find debris... if that. Even if Enterprise makes it past the black hole without being destroyed... it seems likely the crew won't survive."
After the opening credits, T'Pol continues, and the audience gets more context:
"...I'm continuing my analysis of the condition that's stricken the crew. But without Doctor Phlox's assistance, I'm not hopeful about reversing its effects. I'm documenting my findings so that Starfleet will at least have a record of what happened. The symptoms began not long after we set a course for the trinary system. That was nearly two days ago."
Sub-Commander T'Pol was portrayed by Jolene Blalock.
