Question

what is the main source of natural resources according to the text? options: factories, surrounding environment, urban areas, laboratories

Explanation:

To answer this, we analyze the options: Factories produce goods, not natural resources. Urban areas are human - built and not a source of natural resources. Laboratories are for research. The surrounding environment (like forests, mines, water bodies) is where natural resources (like minerals, water, plants) come from.

Natural resources are materials from nature. Factories, urban areas, and laboratories are human - made or related to human activities. The surrounding environment (e.g., forests, mines, water bodies) is the natural source of resources like minerals, water, and plants.
