Final answer:
Quality-cast Telecom's international division would likely be in the Multinational stage, where it operates on a global scale and tailors its business to various regions. International trade enables even small economies to benefit from economies of scale and customer variety through globalization, exemplified by McDonald's global presence.
Step-by-step explanation:
If Quality-cast Telecom has an international division, it is likely that it is participating in the c) Multinational stage of the international arena. This stage typically involves a company that has substantial investments in foreign countries and that operates on a global scale, tailoring products and marketing to each country or region.
When we look at how international trade affects a small economy, it's possible for even a smaller economy to leverage economies of scale by producing goods in high volumes for the international market which can decrease the per-unit cost. Additionally, it enhances competition and offers a variety of goods from several producers, thus benefiting consumers. This demonstrates an aspect of globalization, which also highlights integration through international trade, though it does not necessarily integrate governments.
An example of globalization in practice is the presence of McDonald's restaurants worldwide. It shows how a company's business model, culture, and products are integrated into various countries around the globe, a concept different from the diffusion which is more about the spread of cultural elements from one area to another without significant business integration
