3为何不对？同样削弱了结论（措施），它因。

albert

the line of reasoning of the passage is that because "red color" could give rise to unease of lots people, the color of fire trunk should be changed...

3 is out of scope because how the "red color" cause the unease of different people is not the issue we want to discuss...

But 3 does not mean the different responses of different people, it gives us another reason for unease of people and tell us that actually the unease related with red color are caused by the color of properties of the color itself. Actually, when I wrote here, I found 3 support the conclusion, although it denied the relationship between the red color and fire trucks, but it does mean that changes in the color of fire truck from red to some other colors will benifit the people's reaction.
Thanks Albert.
