Final answer:
Taxes are not considered a factor of production, unlike knowledge, land, and capital.
Step-by-step explanation:
The factor of production that is not considered is Taxes. Taxes are a financial charge imposed by the government on individuals and businesses, and they do not contribute directly to the production of goods and services. On the other hand, knowledge, land, and capital are all factors of production. Knowledge refers to the information and expertise that people possess, which is essential for innovation and productivity. Land includes natural resources like minerals and water, which are used for production. Capital refers to the tools, equipment, and machinery used in the production process.
