The paragraph missing is the following:
Where four decades ago there was rubble, today in West Berlin there is the greatest industrial output of any city in Germany—busy office blocks, fine homes and apartments, proud avenues, and the spreading lawns of park land. Where a city's culture seemed to have been destroyed, today there are two great universities, orchestras and an opera, countless theaters, and museums. Where there was want, today there's abundance.
Answer:
Reagan uses parallelism to compare the past to the present
Step-by-step explanation:
Parallelism is a rhetorical device that balances separate parts of a sentence or a paragraph by using similar construction. It uses words, phrases, or clauses that are grammatically similar or identical in structure, sound, or meter, to show that the ideas are equally important, balanced and to give a natural flow to the piece of writing. This is what Reagan is using when he repeats the words “where” and “today” through the paragraph, and he uses it to compare the past to the present, and show that those ideas are equally important.
