Answer:
D. The output of the United States.
Explanation:
Macroeconomics is a branch of economics that deals with aggregate economy as a whole. The focus of macroeconomics is primarily around large economics issues such as inflation,Gross Domestic Product (GDP), foreign exchange, unemployment, e.t.c. On the other hand, microeconomics deals with economic decision making of individual and firms. Issue likes production, pricing and consumer budget are the focus.
Now with the question, Option A is wrong to be classified as macroeconomics issues because it points at family budgets which is not an issue of aggregate economy. Family budget is purely an issue of microeconomics.
Option B is also wrong to be in the context of macroeconomics. Deciding how many pairs of shoes to buy is entirely an individual economic issue.
Option C is wrong as well because it deals with demand and supply related issue of price, which is an economic issue for firms, and not aggregate economy.
Option D is correct as a topic of macroeconomics because it is related to the aggregate economic issues of national output of the economy of United States. Topics like output of the United States will be discussed within the context of Gross Domestic Product (GDP), which is a macroeconomic issue.
Answer:
Both technicians A and B are correct
Explanation:
A pump check valve is device that allows the flow of any fluid in only one direction and prevents the flow from the reverse direction.
When the pump operates, there is pressure that develops inside the pump. Now when the pump is shut down, the pump check valve is able to hold the pump pressure for sometimes until the pressure inside the pump becomes normal.
When the pump check valve is defective, there is a drop in pressure inside the regulator or the pump. Because of the drop in pressure, it takes long time for the pump to start and hence longer cranking time.
Thus both technician A and technician B is correct.
Hence the answer is ---
Both technicians A and B are correct
D because they do want all their freedom and don’t want the government to intervene
