Unit 8 · Detecting Reasoning Errors
Red Warning Light — Rule Scope Error
Lesson 29 of 34
About this lesson
A flashing red light warns that the processor is starting to overheat. Yifan concludes no flashing means everything is fine. Ria concludes a continuous light means it has overheated. Both are wrong — the rule only defines what the flashing signal means, and nothing else.

Question
Whenever the red light on the side of Yifan's computer is flashing on and off, it means that the processor is starting to overheat.
Yifan said: "The red light isn't flashing at the moment, so the temperature of the processor must be fine."
Ria said: "No, that's not right. The light is on continuously – that must mean that the processor has already overheated!"
If the information in the box is true, whose reasoning is correct?
