1.. modern horse-race coverage focus public
attention on
a. congressional legislative actions.
b. presidential primaries.
c. public policy debates
d. supreme court rulings.

The correct answer is B, presidential primaries. Let's think about why is that: what is the difference between B and the other options?

When we are talking about congressional legislative actions, public policy debates, and Supreme Court rulings, we can hardly have a real conversation with only two possible answers. Public debate is necessarily complex and multilayered; and the main goal isn't one thing or another to win, most of the times, but to achieve the best possible result.

So the press takes advantage of presidential primaries, when besides public debate also individual figures are central and covers it like a horse race. Coverage then gets less political, since it doesn't have much space for healthy and serious debates, and becomes only about the disputing figures.

the correct answer is “opportunity cost”. opportunity cost is what a company misses out because it decided in one option over another one. in this case, the company decided to invest in building a factory so it gave up another possible benefit or profit in order to achieve success with the factory.  

trade-off is not the correct answer since it is a situation in which you accept losing something in return for benefits in other areas.

and finally, consequence is a general term used to accept what it comes when you make a decision. it can be a positive or negative consequence depending if the decision you took was the correct one.
