Read the passage and answer the question:

In thinking about the consequences of globalisation, it is necessary to keep in mind that the same set of policies does not lead to the same results everywhere. While globalisation has led to similar economic policies adopted by governments in different parts of the world, this has generated vastly different outcomes in different parts of the world. It is again crucial to pay attention to specific context rather than make simple generalisations in this connection.

Option 2- Through the visa policies.

Option 4- All of the above.

What is often called economic globalization usually involves greater economic flows among different countries of the world. Some of this is voluntary and some forced by international institutions and powerful countries. This flow or exchange can take various forms. Globalization has involved greater trade in commodities across the globe; the restrictions imposed by different countries on allowing the imports of other countries have been reduced. Similarly, the restrictions on movement of capital across countries have also been reduced. In operational terms, it means that investors in the rich countries other than their own, including developing countries, where they might get better returns. Globalization has also led to these flow of ideas across national boundaries. The spread of internet and computer related services is an example of that. But globalization has not led to the same degree of increase in the movement of people across globe. Developed countries have carefully guarded their borders with visa policies to ensure that citizens of other countries cannot take away the jobs of their own citizens.
