StrengthenDiff: Hardest

Logic Breakdown

Passage Summary: Even though we see more tornadoes on the news now, it is likely just because we have better tools to spot them, not because there are actually more of them.

Conclusion: The actual frequency of tornadoes likely hasn't increased despite the rise in reports.

Reasoning: Technological improvements allow us to detect a higher percentage of the tornadoes that occur compared to the 1950s.

Analysis: The meteorologist is attributing the increase in data to better observation rather than a change in the phenomenon itself. This is a common theme in Logical Reasoning: confusing an increase in observation with an increase in occurrence. To bolster this, we need something that confirms the 'extra' tornadoes were there all along, just hiding from our 1950s technology. Look for an answer that shows the increase is specifically in the types of tornadoes that were previously difficult to detect.

Which one of the following, if true, provides the most support for the meteorologist’s argument?

Correct Answer
C
If large and medium tornado reports are roughly constant, the increase in total reported tornadoes likely comes from small ones that used to go undetected. That supports the claim that the rise in reports is due to better detection rather than more tornadoes.
