In 2017, gas stations in Germany began adopting pricing AI. Research found that in duopoly markets, margins significantly increased — but only when both firms adopted AI- based pricing systems. What key pricing insight does this example best illustrate? A) Simultaneous AI adoption by competitors can lead to coordinated pricing behavior and higher margins, even without direct collusion. B) AI enables firms to perfectly predict consumer demand, reducing price volatility across competitive markets. C) AI adoption helps firms avoid regulatory scrutiny by setting prices algorithmically rather than through negotiation. D) Dynamic pricing algorithms reduce firm profits in duopolies because they drive prices toward marginal cost. E) When one firm in a duopoly adopts AI, it gains a pricing advantage regardless of its competitor’s strategy.

(1 point) For each sequence $a_n$, find a number $k$ such that $n^k a_n$ has a finite non-zero limit. (This is of use, because by the limit comparison test the series $\sum_{n=1}^{\infty} a_n$ and $\sum_{n=1}^{\infty} n^{-k}$ both converge or both diverge.) A. $a_n = (3+4n)^{-7}$ k = B. $a_n = \frac{7}{n^4+n}$ k = C. $a_n = \frac{3n^2+7n+3}{9n^5+4n+4}$ k = D. $a_n = \left(\frac{3n^2+7n+3}{9n^5+4n+4\sqrt{n}}\right)^6$ k =
