Test: Resources- 1 - Class 8 MCQ

A resource is any physical material constituting part of Earth that people need and value. Natural materials become resources when humans value them. Some resources are finite, while others can be replenished at varying rates.

Utility means: 
1. Business: Large firm that owns and/or operates facilities used for generation and transmission or distribution of electricity, gas, or water to general public.

2. Computing: Auxiliary program that performs a specific useful function to maintain, or augment the efficiency of, a computer system. Utilities range from the small and simple to the large and complex, and from being marginally useful to being indispensable. Functions performed by utilities include data compression, data recovery, disk defragmentation, management of computer resources and files, system diagnosis, virus detection, and numerous other.

Some resources can become economically valuable if they are patented and sold. An example is home remedies that were not valuable initially but could become economically valuable if commercialized through patents.
