In a closed-system economy, gross national product is ____ as a 'cost of the system'. The Leontiev model relating the components of society's ____ to resource use has been extended to make possible ____ estimates of 'social entropy'. This kind of work suggests a ____ for minimizing social entropy and real cost in a more advanced economy and technology.

## Answer

In a closed-system economy, gross national product is **regarded** as a 'cost of the system'. The Leontiev model relating the components of society's **demand** to resource use has been extended to make possible **quantitative** estimates of 'social entropy'. This kind of work suggests a **rationale** for minimizing social entropy and real cost in a more advanced economy and technology.

## Explanation

Blank 1 comes before "as," so you need "regarded as," meaning viewed as. "Discarded" looks similar but means thrown away. Blank 4 follows "a" and comes before "for minimizing," so you need a noun meaning a reason. "Rationale" fits. "Rationalism" is a way of thinking, not a reason for doing something.

## Hints

- Look for words that function as the main verb in the first sentence to describe how the product is viewed.
- Consider which noun fits the context of society's requirements and which adjective describes the type of measurement being performed.
