Passage 1 explores the challenges of preserving endangered languages in the face of globalization. The author argues that as dominant languages spread, smaller languages face extinction, thereby losing unique cultural identities. The passage emphasizes the importance of revitalization efforts, especially in local communities, to ensure these languages survive for future generations.

Passage 2, in contrast, looks at the role of technology in language preservation. The author suggests that digital tools and platforms provide innovative ways to document and teach endangered languages. Using mobile apps and online courses, communities can engage younger generations in their linguistic heritage, making it more accessible and relevant in today's society.
