7. Read the following statements and say whether they are true or false. Correct the false statements:

• These were not mass-produced by a mechanical extrusion process in which clay was squeezed by "pressed" through a rectangular die as a continuous column and sliced to size by a wire cutter.
• There was also a proliferation of elaborately shaped and stamped masonry units.
• Timber technology underwent rapid development in the 20th century in North America, where there were large forests of softwood fir and pine trees that could be harvested and processed by industrial methods; steam- and water-powered sawmills began producing standard-dimension timbers in quantity in the 1920s.
• The production of cheap machine-made nails in the 1830s provided the other necessary ingredient that made possible a major innovation in building construction, the balloon frame; the first example is thought to be a warehouse erected in Chicago in 1832 by George W. Snow.
