Acontractor made a small error in laying the foundation of a building. instead of being level, the foundation was at an angle of two degrees. after the building was built, the entire structure leaned dangerously to the left and had to be torn down.

what does this building demonstrate about systems in general?
a.
the affect of a change in a system is always predictable.
b.
systems built by people cannot change.
c.
small changes in a system have only small effects.
d.
small changes in a system can produce very large differences.

Which statement best describes a typical difference that could be found between the "analysis" and "conclusion" sections of a lab report? a) only the "conclusion" describes errors that occurred during the experiment, and only the "analysis" section suggests further research. b) only the "analysis" section includes specific data comparisons, and only the "conclusion" section suggests further research. c) only the "analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data. d) only the "conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.(the answer is b i just took the test)
