Explanation:

The target idea is that Stickeen went from being unimpressive to the most interesting member of the party.

1. The quote from paragraph 4 shows he initially seemed unobservant/motionless, hiding his true nature.
2. The quote from paragraph 7 shows he transformed from the least promising dog friend to the best known, directly demonstrating the shift from unimpressive to the most interesting.

Other quotes either only reference his hidden nature, his mysterious fate, or his unknowable skills without showing the full arc of his transformation.

Answer:

• "He sometimes appeared motionless, and as unobserving as if in deep sleep, but I discovered that somehow, he always knew what was going on." (paragraph 4)
• "At first, he was the least promising and least known of my dog friends. He suddenly became the best known of them all." (paragraph 7)
