Step-by-step explanation:
The examples given can be categorized as either belonging to the Biological Information System (BIS) or the Behavioral Activation System (BAS).
Here we have reaction systems described by the equation 2A = B. These examples pertain to the BIS system as they involve chemical reactions and the formation of products.
On the other hand, in Section 19.3.1, we have instances where the economy is compared to analogous systems. This example falls under the BAS system as it deals with economic systems and their comparison.
