Question

but this answer is too simple. the foundation for my success with communication was laid in my earliest years, at a deaf preschool. that was perhaps the only time in my life when i experienced full communication access each day. everyone—students, teachers, speech therapists, parents, siblings—signed. from ages 2 to 5, i lived, breathed and conversed with people like me—at least, as alike as a young child understands. there was no reason for me to doubt myself or my abilities, so i grew fluent and confident with language. i learned its nuances, its facial and emotional expressions. i learned that it was not inaccessible, as it would sometimes later seem.
self - confidence fuels the desire to practice and protects against the degradation of communication breakdown; but my ability to lipread is attributable not only to my own efforts, but also to the contributions of others. when i was less than a year old, my parents started me in speech therapy, which i continued for 18 years. there, i encountered the visual and physical fragments of the sound that was so absent from my world. this sound was mysterious to me. i could not grasp it—even with hearing aids—but i could see it. under the tutelage of a succession of speech therapists, with support from my family, i became student of its aftereffects.
how does the text structure in paragraph 4 - 5 with the video feature impact the text?
what text structure does the author use in paragraphs 5?

Explanation:

For the first question, without knowing the video feature, we can only analyze the text - structure impact within the paragraphs. Paragraph 4 sets the foundation of the author's communication success in early years at a deaf preschool. Paragraph 5 builds on this by adding another factor (lip - reading ability) and the contributions of others. If there was a video, it might visually reinforce these written ideas. For the second question, paragraph 5 uses a cause - and - effect structure. The cause is the early speech therapy and support from family and speech therapists, and the effect is the author's development in lip - reading and understanding of sound fragments.

Answer:

For the first question: Without video details, the text structure in paragraphs 4 - 5 builds a narrative of the author's communication development. If there was a video, it could visually enhance these ideas.
For the second question: Cause - and - effect text structure.
