Yes the retailer A is the efficient Frontier.
<h3>How is retailer A the efficient frontier?</h3>
When two retailers are in a competition based on costs and ambience, they would be identical. The retailer called A is the cheaper person than B. This means he has the better ambience hence A is the more efficient frontier.
The portfolios that are known to be at the bottom or below the frontier are those that would be termed sub optimal. The reason is because there are no sufficient returns that exists for the level of risks that they may carry.
Because retailer A is cheaper and it has better ambience than we are able to know that the efficient frontier is that of retailer A out of these two.
The importance is that it helps the retailers to be aware of the potential risks that their portfolios and the results that they carry.

Answer: an interview with an agricultural specialist
Explanation:
The correct answer is - 2. There's an increase in the number of snakes and insects, and the storks face increased competition for food.
The significant decrease in the number of eagles, because of the human activity, and of the rabbits, because of a virus, has been of great use for the populations of the snakes to increase, as well as the populations of the insects. That has happened because the snakes lost their predator, and the insects lost a competition for a food source, so their numbers rose.
On the other hand, because of the increase of the number of snakes, the storks had started to face increased competition, as both have the same food source, the frogs.
