A city planner argues that because every bridge in the county was inspected and found to be structurally sound, the entire county's transportation infrastructure is therefore in excellent condition.
Which one of the following identifies the most significant logical flaw in this reasoning?
- It judges a sample of bridges that is too small to support a conclusion about all of the county's bridges.
- It concludes that an entire system has a quality merely because one type of component within it has that quality.
- It neglects the chance that the bridges will deteriorate at differing rates in coming years.
- It treats a condition sufficient for sound infrastructure as though it were necessary for sound infrastructure.
- It assumes that sound bridges are the single most important element of any transportation network.
