Read the paragraph. Bridges, railroads, tall buildings, ships, airplanes, telephones, and electric lighting would all be lost if we mislaid or lost our ability to count to
compute stress and strain, to lay out angles and curves, or to weigh and measure the exact quantities that modern science demands. Living
onditions would go back to a simpler form with small communities of tiny huts amid people bartering one simple commodity for another. The
world, as we know it could not survive without mathematics. Number systems have been developed in response to humanity's increasing needs
md desires. Without them, both our work and our play would, in large measure, be lost to us.

With which statement would the author be most likely to agree?

1. Number systems are a foundation of cultural progress.

O 2. Our culture is very unstable because of its dependence on mathematics.

3. Basic human needs don't change very much throughout history.

4. Play is a natural human activity which needs little direction or structure.
