Closing the gap is a phrase used to describe the process of bridging the divide between two different groups or entities. It is often used in the context of social and economic inequality, but can also be applied to other areas such as education, healthcare, and technology. The term 'gaining' is related to this concept, as it implies that one group is making progress towards achieving parity with another. Gaining can refer to both tangible and intangible benefits, such as increased access to resources or improved quality of life.
