Opinion polls are made picking a portion of a population and asking them some questions about a given subject. These answers are, then, used to make an idea of what that population thinks about that subject.
The problem is the impossibility of asking the entire population what they think about the subject.
For example, 80% of the persons the poll interviewed agreed that studying is good as early as five years old. The opinion poll, then, will say 80% of the people from that location agreed to that studying starting from five years old is good. The persons asked totalize 5000, while the total population of that place is, for example, 100.000.
So, the statement that defines opinion pools is: opinion pools can give an idea of what a population thinks, but it might be misleading and can never be accurate enough.

The correct answer is: "Companies are selling shares of ownership and a share of its profits in exchange for money it can use to operate their business."
Shares are fractions of a corporation's social capital, which is equally divided in many pieces. Each of these shares is traded in stock markets. When investors buy stock from a company, they become owners of the company in the same proportion that the number of shares bought represents of the total social capital. Stockholders will make profit by receiving, every year, a percentage of the total profit generated by the company. The amount received is called dividend.
Moreover, stock investors can also make money by selling the shares at a higher price than the buying price. If the company functions properly and keeps on generating profits, the value of its stock in the financial markets will rise.
