Concept:Authenticity means the text is original and unchanged, reflecting natural language from a real‑life context.
Explanation:A text is a meaningful sequence of spoken or written language. It can be as short as one word (e.g., “Danger”) or as long as a novel.
Authenticity requires that nothing in the original text is changed, including its presentation and layout.
An authentic text comes from a natural, everyday context—like a newspaper article—and uses language developed through real human usage, not artificial construction.
Such texts connect learners to real‑world language and provide relevant information for learning.
Thus, authenticity is about the text’s origin in a natural context and its natural language use.
Answer:B. origin of the text from a context and natural language use.
