29. Sociologists use graphs to model social relationships. A social network (not to be confused with a network) is a graph where the nodes represent "actors" (e.g., people, companies) and the edges represent relationships, or "ties," between actors (e.g., friendships, business partnerships). Con- sider the social network in Figure 2.9. Figure 2.9 Social network for Exercise 29. (a) A clique in a social network is a group of actors who all have ties to each other. What is the largest clique in the social network in Figure 2.9? (b) If you had to choose the most important actor in this social network, who would you pick? Why? (c) Suppose the actors represent people and the ties represent acquain- tances. If the people in this social network continue to interact, which two (currently unacquainted) actors would you most expect to be- come acquainted? Which two actors are the least likely to become acquainted? Why?

Q4 Revenue equivalence Ill Consider a sealed-bid auction in which the highest-bidder wins and pays the amount that they bid and the lowest bidder receives a payment equal to the difference between the first- and second-highest bids. Does this auction pay the seller the same revenue as the four standard auctions? (That is, does the revenue equivalence theorem apply here?) Why or why not? Be specific.
