Final answer:
The conclusion of the argument by analogy is that learning TEX requires a significant amount of effort, comparing it to building a full-scale spacecraft and running a shuttle program. The conclusion questions whether the person believes they can achieve this with minimal effort.
Step-by-step explanation:
The conclusion of this argument by analogy is that learning TEX, the scientific word processor language, takes a significant amount of effort. The analogy used in the argument compares learning TEX to building a full-scale, working Challenger spacecraft and running a shuttle program with just a little effort. The purpose of this comparison is to highlight the difficulty and complexity of learning TEX. The conclusion questions whether the person believes they can accomplish such a challenging task with minimal effort.
