2. Indirect Democracy
3. Tribuni Plebis (Tribunes of the Plebs)
4. Law

Explanation:
In Athens, the Greeks developed a DIRECT DEMOCRACY by having citizens make laws directly. In Rome, the Romans developed a INDIRECT DEMOCRACY, also known as a representative democracy. Romans created the TRIBUNI PLEBIS, which gave the plebeians protection under the LAW. In summary, the Greeks developed ATHENIAN DEMOCRACY and the Romans added REPUBLIC government.
 
        
             
        
        
        
Answer:
People make choices about what to buy. 
Explanation:
Opportunity cost also known as the alternative forgone, can be defined as the value, profit or benefits given up by an individual or organization in order to choose or acquire something deemed significant at the time.
Simply stated, it is the cost of not enjoying the benefits, profits or value associated with the alternative forgone or best alternative choice available.
Hence, the opportunity cost of buying a product is the utility (satisfaction) that could be derived in another product using the same amount of money.
For example, if you decide to use your money to buy a Playstation 5, your opportunity cost would be the satisfaction you could have derived if you had invested the same amount of money in buying a bike for easy transportation. 
Hence, opportunity costs exist when people make choices about what to buy.

Statements C and D are correct. 
In America, the development of canals helped lead to the increase in population for several towns/cities that were very seldom settled before. A perfect example of this would be the development of the Erie Canal in New York. Thanks to the Erie Canal, several cities population grew immensely during this time (like Utica, Rochester, and Albany).
Along with this, connecting canals with other waterways made for convenient way of shipping goods and materials. This reduced the cost of shipping goods, making for lower prices for American consumers.
