问题     While it may be unlikely for a computer to write a best seller, a technology expert has created a computer program that writes its own fiction stories with minimal user input. The program, called MEXICA, is the first to generate original stories based on computerized representations of emotions and tensions between characters.
    An Internet survey was carried out to see the popularity of the computer-generated stories, other computerized stories and stories written solely by a human. The result was that readers ranked MEXICA stories highest for flow and coherence, structure, content, suspense and overall quality. Rafael Pérezy Pérez, the creator of MEXICA, explained that a story might begin with something as basic as, "The enemy wounded the knight. The princess cured the knight. The knight killed the enemy. The knight rewarded the princess. The end. "
    The program reads characters as variables (变量) and assigns a numerical value, between a continuum(连续体) from -3 to +3, to emotional connections that are defined as either amorous (多情的) or non-amorous. The numerical value is equivalent to the degree of emotion, with -3 being intense hate and +3 being intense love. The program also understands story tension, such as linking the word "wounded" with tension. This too is assigned a numerical value.
    Once these clusters of emotional links and tensions are established, the program begins what is called an "engagement reflection cycle". Basically this involves searching a database of story actions and other happenings, which are called "atoms", and determines the best match for the characters and contexts for that moment.
    The process repeats itself again and again until the system can no longer make any matches. At this point, the computer analyzes the story for coherence and "interestingness". The program views a story as interesting when tension levels increase and fall throughout the piece. If the program finds that the story is boring or incoherent in places, it will replace or insert atoms until a version is thought to be satisfactory.
How does the computer system elaborate the characters in its story?
选项 A、Characters in the story are given different numerical values.
B、Characters are developed according to the tensions preset.
C、Characters are designed by using the language MEXICA can understand.
D、Each character is valued for its value in the construction of the story.
答案A
解析 推断题。题干提问计算机是如何描述故事中的角色的。根据关键词characters定位到文章第三段第一句，程序把故事中的角色看做变量(variables)，并赋予变量一定的数值(numerical value)。
