In the third paragraph of John F. Kennedy's Inaugural Address, Kennedy makes a comparison between the world during his time and the time the nation was founded. What idea is Kennedy most likely attempting to explain by this comparison? Our country's ability to change the world with science is the way of the future. We must be more generous than in past times if we are to end poverty. Despite many major developments, the basic principles of the country’s founders are still at play. The many changes in the world make it difficult to remember a time when life was much different.
