Why These Connect
The narrative assertion
"The Doctor’s observation that the hand’s structure is silicon-based (from X-rays) sets up the need to examine a sample under an electron microscope. This technological escalation reveals the hand's regenerative capacity—a discovery that would be impossible without the earlier X-ray insights."
