Explanation:

The passage shows that Dalgard observes the monkeys' behaviors (going berserk, fixed expressions) and mentions their clinical signs (depression, going off feed, leading to death). The first option "Dalgard sees clinical signs of depression and illness in the monkeys" encompasses these key elements. The second option misses the mention of Dalgard's role. The third option only focuses on fear of space - suited men without highlighting the clinical aspect. The fourth option is contrary to the text.

Answer:

Dalgard sees clinical signs of depression and illness in the monkeys.
