Question

Analyze the following excerpts representing two distinct sources regarding the cultural and economic revitalization of traditional clay pottery in Pomaire, Chile:

**Source A (Audio Broadcast Transcript: *Voces del Patrimonio*, Chilean Cultural Radio)**
"Master potter Teresa Morales explains that while mass-manufactured synthetic cookware initially caused a sharp drop in artisan revenues, the greatest existential threat today is generational rupture. Younger residents increasingly migrate to urban centers, leaving fewer apprentices to learn ancestral, unglazed pit-firing techniques. In response, Morales's workshop partnered with local educators to launch an intergenerational apprenticeship academy. Morales emphasizes that adopting digital sales platforms and nationwide direct delivery has revitalized sales, but insists that the foundational clay-mixing formulas and manual techniques must remain unaltered to preserve cultural integrity."

**Source B (Print Text Excerpt: *Regional Heritage & Economic Bulletin*)**
"A comprehensive assessment of Pomaire's artisan sector confirms that pottery collectives face severe sustainability hurdles stemming from demographic aging and youth out-migration toward metropolitan labor markets. Field surveys show that demand has rebounded substantially following the integration of decentralized e-commerce channels. However, the report stresses that economic viability continues to depend strictly on maintaining time-tested, manual fabrication protocols without substituting industrial kilns or synthetic glazes. Additionally, geological surveys confirm that local deposits of natural raw clay remain plentiful and accessible, refuting claims that material scarcity caused the historical trade slump."

Match each analytical claim on the left with the source attribution that accurately describes its evidentiary support on the right.
