Explanation:

1. "Elucidated" means to make something clear or explain it. "Prospect" refers to a possibility or likelihood of something happening. "Specter" is a ghost - like figure. "Improvised" means to create or perform something without preparation. After George explained his plan, the possibility of climbing the mountain became clearer, so "elucidated; prospect" is correct.
2. "Lucid" means clear and easily understood. "Specter" is a ghost. "Providential" relates to divine intervention, "phototropic" is about the response of organisms to light, and "invidious" means likely to cause resentment. Daria was upset she couldn't give a clear explanation of her discussion with the ghost - like figure in her nightmare, so "lucid; specter" is right.
3. "Providential" means happening at a favorable time; opportune. "Phototropic" organisms respond to light. "Photogenic" is related to being suitable for photography, "circumspect" means cautious, "invidious" is likely to cause resentment, "translucent" allows some light to pass through, and "lucid" is clear. The opportune discovery of a light - responding organism helped researchers, so "providential; phototropic" is correct.

Answer:

1. B. elucidated; prospect
2. C. lucid; specter
3. C. providential; phototropic
