Builder: Within ten years, most of the new homes constructed in North America will have steel frameworks rather than wood ones. After all, two-by-fours and two-by-sixes—the sizes of lumber most commonly used in home construction—are deteriorating in quality and increasing in cost, while environment-friendly steel is decreasing in cost. In addition, unlike wood, steel will not warp, rot, or split.

Summarize Argument
The author concludes that within ten years, most new homes made in North America will have steel frameworks instead of wood ones. This is because the sizes of lumber most commonly used in home construction are getting worse in quality and are getting more expensive. In addition, steel has an advantage over wood in that steel will not warp, rot or split.

Notable Assumptions
The author assumes that the steel required for houses is not getting worse in quality. The author also assumes that there aren’t other disadvantages about steel compared to wood that might outweigh the disadvantages brought up about wood.

A
Over the next ten years, labor costs in the home construction industry are expected to rise significantly.
This doesn’t differentiate between steel and wood labor costs. We have no reason to think this would affect steel more than wood.
B
Steel-framed homes do not have to be treated with pesticides or other chemicals that can contribute to indoor air pollution.
This is a positive aspect about steel. If anything, this strengthen shte argument.
C
Because lumber prices have increased over the last decade, currently most new homes are built with steel frameworks.
If anything, this supports the author’s prediction that most new homes constructed will have steel frameworks.
D
Training home construction workers to work with steel is very costly.
This is a negative aspect about steel that might outweigh whatever advantages steel has over wood.
E
The number of houses built each year is expected to decrease over the next decade.
This doesn’t differentiate between steel and wood. We have no reason to think this would affect steel more than wood.
