Read the passage and choose the correct answer.Wood has long been a popular building material in North America because it has generally beenplentiful and cheap. Swedish settlers in Delaware built log cabins as early as 1630s. In New England, Britishcolonists built wooden “saltbox houses”. Most of the wooden homes of Colonial times could be built withsimple tools and minimal skills.In the early 19

^th

century, the standard wooden house was built with beams set into heavy posts and heldtogether with wooden pegs. This method of construction was time- consuming and required highly skilledworkerswith special tools. The balloon- frame house, invented in 1833 in Chicago by a carpenter from Hartford,Connecticut, used a frame of lightweight lumber, mostly 2x 4 and 2 x 6 inches. This type of house could beassembled by any careful worker who could saw in a straight line and drive a nail.This revolution in building was made possible by improved sawmills that could quickly cut boards to standardsizes and the lower cost of lumber that resulted. There were also new machines that could produce hugequantities of inexpensive nails. Skeptics predicted that a strong wind could send such houses flying through theair like balloons and, at first "balloon frame" was a term of derision. But the light frames proved practical, andwooden houses have been basically built this way ever since.
