What is an invention?

A modification of existing products
A system, product, or process that has never existed before
A design change to improve functionality
A method to increase market share

The correct answer is: A system, product, or process that has never existed before

An invention refers to a system, product, or process that has never existed before. This definition underscores the essence of invention as the creation of something entirely new rather than a mere improvement or adaptation of what is already available. Inventions are groundbreaking; they introduce novel concepts or technologies that can lead to significant advancements in various fields. The other choices focus on modifications or enhancements of existing items rather than true innovation. For instance, the first option relates to improvements on already available products, suggesting an evolution rather than an origination. The third option emphasizes design changes which aim to enhance functionality, again highlighting adjustments to prior designs. The fourth option refers to strategies for market growth, which are more about business practices than the intrinsic nature of an invention itself. Therefore, the correct answer emphasizes the originality and novelty that define an invention.
