What are the differences between Algún/ Alguien/ Alguna?
Algún refers to a masculine noun, and alguna refers to a feminine noun. Both can be used to refer to something/anything else. For example, "¿Hay algún libro aquí?" (Is there any book here? We use "algún" because "libro" (book) is masculine in Spanish. The difference now is that alguien is used when referring a person (someone/somebody) wihout adding any further information about grammatical number or gender. For example, "Hay alguien aquí" (There's someone here).
Why is a large GDP a good thing?
A large GDP is desirable because we can enjoy more goods and services. GDP is a good proxy that there are more incomes to buy goods and services and our quality of life (In terms of having a variety of products that make our lives easier) can be higher than with a small GDP. However, it is not a perfect measure of well-being. For example, GDP excludes the value of leisure and the value of a clean environment.
When the demand for a product or service is higher than the supply this causes what?
When there is a higher quantity demanded, we expect a shortage occurs. It is a situation where the amount of a good or service supplied in the market is not enough to satisfy the buyers needs.
