The reaction to a fire alarm should be almost automatic.
While the mode for selling land heavily relies on external resources, those are at most secondary in the reaction to a fire alarm, and in driving behaviour.
The examples range from utmost simplicity (responding to a fire alarm in a building) to high complexity (responding to a fire as a member of a fire brigade).
The modes for responding to a fire alarm and for selling land are fairly fixed, while the modes for driving and for a fire brigade are highly plastic.
For much the same reason, a fire alarm should be automatic, and not subject to whim, although one's reaction to a fire alarm should be purposeful.
The solution after the fire alarm activities are passed is more trade, more harmonization, functioning internal market with goods and even more with services.
The fire alarm, however, was not fully operational and it had not been tested within the previous three months.
The fire alarm system went off and the staff and pupils were evacuated safely within two minutes.
