Which of the following statements is correct?

a- The consequences of globalisation are confined only to the sphere of politics and economy.
b- Globalisation has no influence on what we think are our preferences.

Neither of them is correct.

The consequences of globalisation are not confined only to the sphere of politics and the economy. Globalisation affects us in our homes, in what we eat, drink, and wear, and indeed in what we think.  It shapes what we think are our preferences. The cultural effect of globalisation leads to the fear that this process poses a threat to cultures in the world.
