Answer:
D
Explanation:
When interest rate is above the equilibrium level, people would be less willing to hold cash. Instead they would prefer to save or invest in interest-bearing bonds. This is because as a result of the higher interest rate, interest paid on their deposit and investment would be higher.
As a result of the increase in savings, there would be an increase in the supply of loanable funds over demand for loanable funds. This would lead to a reduction in interest rate until equilibrium interest rate is reached.
The question is incomplete. The complete question is :
The Jackson family is undecided about whether or not to buy a new car. If the probability is .9 that they will buy one, and if the probability is .3 that they will buy a Ford, and if the probability is .4 that they will purchase a car getting more than 20 miles per gallon, what is the probability that they will buy either a car getting more than 20 miles per gallon or a Ford, if all Fords get more than 20 miles per gallon?
Solution :
Given that :
The probability of buying a new car, 
Probability of buying Ford = 0.3
That is, if Jackson family buy a car that is a ford car, 
= 0.27
The probability for getting more than 20 miles per gallon = 0.4
That is if Jackson family buy a car that have more than 20 miles per gallon mileage, 
The conditions
All of the car have more than 20 miles per gallon mileage.
It means that buying a ford car is subset of getting more than 20 miles per gallon.
Therefore, the probability of buying a car either getting more than 20 miles per gallon or ford = 
Therefore,
= 0.36
Thus the probability that Jackson family is buying a car either getting more than 20 miles per gallon or ford is 0.36
These is a major advantage of a market economy is it can change direction rapidly when needed as markets change. Thus second option is correct.
<h3>What is Market Economy?</h3>
Market Economy refers to the economy in which the prices of the goods and services are determined by the two market forces that are supply and demand.
There is a less control of the government in the market economy and therefore all the decisions are taken by the private individuals. Thus option 1st is incorrect.
The Prices of the goods and services are determined by the supply and demand forces and the prices are kept as per the affordability of the customers. Thus option 3rd is also incorrect.
Therefore the correct option is 2nd one as the market changes the price of the good and services are also effected and get changed.

<u>Explanation</u>:
Subsidies are meant to reduce the money paid by buyers for units of commodity from the producers, while also reducing the selling price imposed by the producers on their sellers.
For example, the initial cost per unit of a popular commodity is $19 and the government then offers a $9 per-unit subsidy for buyers.
Consumer surplus= $9
Producer surplus= 10+9=$19
