Answer:
What does a turntable built into a track look like?
Giving a broad overview of central ideas.
Explanation:
First question:
In the given excerpt from "The Building of Manhattan", the speaker provides a description of the building. The narration includes a description of "a small narrow-gauge track system" and also "Turntables built" on the tracks. While the rest of the description is easy to understand and imagine, the question that can be answered only with an illustration was the question of what a turntable built on a track looks like.
Second question:
Summarizing is when the important points are taken from a passage and restated whereas a paraphrase is when the text is rephrased. So, giving a broad overview of central ideas is an element of summarizing but is not paraphrasing.
