Answer and Explanation:
1. The repetition presents a combat tone, because the author of the text shows that there are more important things to be combated through the struggle than its deficiency. This is because these things are defeatable, the deficiency is not. Deficiency must be understood and accepted in the best possible way, but prejudice, intolerance, ignorance and discrimination are defeatable and they must be combated.
2. This shows the reader that people with disabilities are not warriors, but normal people with their own causes and opinions that must be respected, as disabilities are part of what they are, but there are social and political issues that affect them intensely and these do need to be combated.
