This question is about "DR. HEIDEGGER'S EXPERIMENT"
Answer:
C) he is interested in its possibilities for him.
Step-by-step explanation:
When Colonel Killigrew overhears Heidegger talking about such a fountain of youth, he doesn't believe anything he has heard. However, he is curious and in paragraph sixteen we can see that they are interested in the possibilities that this source can bring to him. We can see this, because, after the narrator claims that the colonel did not believe anything he heard, the colonel says "and what may be the effect of this fluid on the human frame?"
