A successful patent infringement suit can require the defendant to pay monetary damages to the patent holder in addition from stopping their wrongful use of the patent.</span>
Answer:
The correct answer is option d.
Explanation:
The most effective model to understand the effect of change of a variable on other variable is by assuming other factors to be constant. This simplifies the model and helps in easily understanding the relationship between the two variables.
Though the assumption of other things being constant does not apply in the real world, it is still used as otherwise change in other factors would complicate the model. If several factors change it would be difficult to understand the relationship between variables.
Here, to study the effect of change in the price of grapes on the market for wine, it is necessary to assume other factors such as income, consumer preferences, etc to be constant.
A National Debt is the amount of money obtained by one country from another that has not been paid. This can effect a country by means of loss of land actually owned, or it can cause agencies (e.g. Social Security Administration) to be cut on their budget. Meaning the agency to be cut of operational funding will loose a certain amount of funding until funds are found. Normally multiple agencies are cut to obtain some of the money to pay back the debt but this can really hurt agencies for reasoning of staffing as well as other operational costs. Hope this helps!
