Final answer:
The words 'conceivable' and 'solved' portray a cautiously optimistic view of human capability to overcome space colonization challenges, with 'conceivable' implying potential and 'solved' indicating solutions.
Step-by-step explanation:
The author’s use of the words “conceivable” and “solved” in the paragraph from the section “Problems Could Multiply” serves to develop their point of view and the purpose of the text. “Conceivable” suggests that while it is within the realm of possibility that humans could overcome the outlined problems, there is an underlying sense of doubt or uncertainty about this outcome. The author's specific choice of “conceivable” indicates a cautious optimism about humans adjusting to and potentially solving the problems of space colonization. In contrast, the word “solved” indicates that there are potential solutions to the problems mentioned, reinforcing the idea that human ingenuity may indeed find ways to overcome the challenges of space travel.
Throughout the text, it is clear that the overarching theme is about the distinction between challenges and predicaments. The author stresses that the problems humanity faces with regards to living on a finite planet and aspiring to a space-faring future are complex and interconnected, more akin to predicaments than easily solvable problems. This wording reflects a sense of the gravity and complexity of the situation rather than a simplification of the issues at hand.
The correct answer to the student's question is, therefore, option (a): “Conceivable” suggests a positive outlook, while “solved” indicates potential solutions to the problems, as the combination of these words portrays a cautious yet hopeful attitude towards human capability in resolving space colonization issues.
