The larger a bridge, the greater its exposure to forces that can cause it to collapse. Since the construction of the Golden Gate Bridge in 1937, more than a dozen longer suspension bridges have successfully been built globally without incident. Furthermore, the only suspension bridges that have collapsed since 1937 have all been shorter than the Golden Gate.
Which of the following, if true, best explains why only suspension bridges shorter than the Golden Gate have collapsed since its completion?
A. A suspension mechanism becomes more viable for a bridge design as the span distance becomes longer.
B. All but one of the suspension bridges longer than the Golden Gate have been built outside of the United States.
C. In most instances, the size of a construction project is directly proportional to the care exhibited in its design and execution.
D. The principles underlying the construction of suspension bridges have not changed markedly since the Golden Gate Bridge opened to traffic in 1937.
E. More suspension bridges have collapsed in the past 50 years than have any other type of bridge used in more than ten countries worldwide.

B. All but one of the suspension bridges longer than the Golden Gate have been built outside of the United States.
C. In most instances, the size of a construction project is directly proportional to the care exhibited in its design and execution.
D. The principles underlying the construction of suspension bridges have not changed markedly since the Golden Gate Bridge opened to traffic in 1937.
E. More suspension bridges have collapsed in the past 50 years than have any other type of bridge used in more than ten countries worldwide.
Choice A: No. That a suspension mechanism becomes more viable for a bridge design as the span distance becomes longer provides no information to explain why the only suspension bridges that have collapsed since 1937 have all been shorter than the Golden Gate.
Choice B: No. That all but one of the suspension bridges longer than the Golden Gate have been built outside of the United States provides no information to explain why the only suspension bridges that have collapsed since 1937 have all been shorter than the Golden Gate.
Choice C: Yes. That in most instances, the size of a construction project is directly proportional to the care exhibited in its design and execution provides an explanation for why the only suspension bridges that have collapsed since 1937 have all been shorter than the Golden Gate.
Choice D: No. That the principles underlying the construction of suspension bridges have not changed markedly since the Golden Gate Bridge opened to traffic in 1937 provides no information to explain why the only suspension bridges that have collapsed since 1937 have all been shorter than the Golden Gate.
Choice E: No. That more suspension bridges have collapsed in the past 50 years than have any other type of bridge used in more than ten countries worldwide makes it less reasonable that the only suspension bridges that have collapsed since 1937 have all been shorter than the Golden Gate.
