Answer to Question 1

B

Answer to Question 2

Cartels are typically kept secret because they are illegal. In the United States and many other countries, it is illegal for firms to collude to form a cartel. It is illegal because firms collude in order to restrict output, raise prices, and capture consumer surplus so that they increase their economic profit.
