Final answer:
The best example of interconnected technological systems is a person increasing the heat setting on a thermostat, which turns on the furnace.
Step-by-step explanation:
The best example of interconnected technological systems is a person increasing the heat setting on a thermostat, which sends a signal that turns on the furnace.This example involves multiple components: the person, the thermostat, and the furnace. When the person increases the heat setting on the thermostat, it sends a signal to the furnace, which then turns on to provide heat. This demonstrates how different technological systems work together to achieve a desired outcome.
