Q1 Minimax Consider the zero-sum game tree shown below. Triangles that point up, such as at the top node (root), represent choices for the maximizing player; triangles that point down represent choices for the minimizing player. Outcome values for the maximizing player are listed for each leaf node, represented by the values in squares at the bottom of the tree. Assuming both players act optimally, carry out the minimax search algorithm. Enter the values for the letter nodes in the boxes below the tree.

The NBA stands at the dead-center intersection of two rampant social dynamics: the ascendancy of hip-hop culture and 21st-century marketing's sworn duty to easily definable demographic group. Break yourself into generalized demographic qualities: gender, age, race, economic class. There is full range of music, TV shows, movies, and website explicitly designed to keep you warm and toasty in your comfort zone, free from sharp edges.
The NBA as it stands today has plenty of sharp edges and has a serious image problem; more than any other sports. For years, whites make up a majority of fan base, blacks make up a majority of players. And those players have benefited from ever-upward-spiraling paychecks, they've exercised their influence' to shape the sight of the game around them in their own image.
But the NBA is still all about improvisation, artistry, jazz, poetry on the way to and above the rim. And while we appreciated the artistry in and of itself, the fact that we can't do it puts many fans at some kind small, but measurable emotional distance from the game. For the white audience, the skill divide one thing. There always been players that could do things the rest of us couldn't. What's freaking white Americans out is the way NBA is embracing every element' of hip-hop culture—the music, the fashion, the attitude, everything...
Many events, stories hurt NBA, cementing its lawless-blacks image in observers' minds. Referring to the word "thug", that's operative in short-handing the new NBA culture, as many observers noted. "Thug" was so-opted by black culture sometime during the Tupac Era. When people slag NBA' players as "thug", it's good bet they're not taking about Adam Morris or J.J. Redic. It's absolutely a racial tag.
The NBA, more than any other sports entity, has potential to be a bridge between cultures, a way to bring both sides together in cheering some best athletes of any color. It's already produced Jordan, the most widely known athlete in history, and it's gaining ground fast on soccer as the world's best known sport. But it's fragile indeed, with fans in colors viewing basketball as a zero-sum game, where every stereotypically black or white culture apparently forces out it's ethic opposite. But with serious image problems, another slat falls out of the bridge. And it's not hard to imagine a time when nobody will be interested in crossing over.
Why isn't the world singing the praise of the NBA？
A．NFL, NASCAR, MLB are better than NBA.
B．Because of the racialism in NBA.
C．The NBA today has a serious image problem.
D．White people don't like NBA games.

Directions: Read the following four texts. Answer the questions below each text by choosing A, B, C or D . Mark your answers on ANSWER SHEET 1.
Crime is significantly higher in the US than anywhere else in the developed world. Thanks to the political power of the National Rifle Association, Americans have access to deadly weapons, and use them, to a degree that astonishes observers abroad. Americans possess an estimated 60 million hand-guns. Since 1960 the rate of murder crime per capita has grown by 35 percent, a truly horrible statistic. Violent death rates per capita are four or five times higher than in Western Europe (while rape rates are seven times higher, and forcible robbery rates some four to ten times higher). Experts suggest that this violence has cultural roots, and cannot simply be linked to poverty. New York's murder rate is far larger than that in the slums of Calcutta, for example, and in prosperous Seattle --recently rated the number one city in the United States for "live ability" the murder rate is seven times of Birmingham, England. Nor is violence owing to lack of police efforts and checks; at the last count, American prisons were holding more than a million convicted prisoners, a proportion of the population larger more than in South Africa or the former USSR. Three thousand out every 100,000 black American males are in prison, whereas South Africa managed to preserve apartheid by imprisoning 729 black males per 100,000.
Doubling the number of people behind bars during the 1980s has not been very effective, therefore, in dealing with the erosion of American society, partly because of the difficulty of at tempting major social reforms in a politically decentralized, libertarian society. Any attempt to relieve homelessness and poverty in the inner cities--and the rural South --might cost a great deal of money, and a transfer of resources from the better-off (who vote) to the poor(who don' t). Since the Boston Tea Party, middle-class Americans have had a deep aversion to paying taxes' with some justification, since unlike Europeans they do not enjoy in return such middle-class benefits as: free college tuition, health care, subsidized cultural events, efficient public-transport systems, and so on. Perhaps funds could be made available if productivity and real growth were bounding upward. When they are not, changes in spending priorities become part of a "zero-sum game", blocked by groups who lose out.
Which of the following sentence is true according to the passage？
A．Americans can easily get weapon from the National Rifle Association.
B．The National Rifle Association had successfully prevented the government from banning civilian's access to deadly weapons.
C．Observers abroad are astonished to a great degree that Americans have access to deadly weapons.
D．The author expresses his thanks to the National Rifle Association.
