Analysis is well-structured and logical. Let's summarize your reasoning:
Statement 5: This statement serves as the opening sentence, introducing the broader idea that people with hearing impairment have faced marginalization for millennia.
Statement 3: This statement follows logically after 5, providing details on how people with hearing impairment were marginalized.
Statement 4: It forms a pair with 1, as the possessive pronoun ""his"" in statement 1 logically refers to Pedro Ponce, who created the sign language.
Statement 2: This statement is excluded as it doesn't fit into the logical sequence formed by 5, 3, 4, and 1.
Your careful identification of pairs and the logical order of statements results in a coherent paragraph (5341)
