The trend toward a single global market that crosses national borders is known as ____.

The correct answer, globalization, refers to the process of increasing interconnectedness and interdependence among countries, particularly in terms of economics, culture, and politics. It involves the reduction of barriers to trade and the movement of goods, services, and individuals across borders. This phenomenon enables businesses to operate on an international scale, allowing for greater access to markets, diversified supply chains, and a wider consumer base.

Globalization has significant implications for economies, as it can lead to increased competition, innovation, and efficiency. It is driven by advances in technology, communication, and transportation, making it easier for companies to engage with global markets and consumers.

In contrast, downsizing refers to the reduction of a company's workforce to improve efficiency or reduce costs, which does not directly relate to the concept of crossing national borders. Distance learning involves educating individuals remotely, typically through online platforms, which is also not directly connected to the concept of a global market. Lastly, global warming pertains to environmental changes caused by climate change and does not relate to market dynamics or economic integration.
