Table

At the Moslund Plant, the assembly line consists of 3 conveyor belts. In addition, there are 3 inspection posts, one at the end of each conveyor belt. In Year 10 (Y10), 15 workers were employed directly on the line; 3 of these workers staffed the inspection posts, one at each post.In Y10, the Moslund Plant assembly line had an output of 250,000 units and generated a profit of $15,000,000.

For Year 11 (Y11), the Moslund Plant assembly line was modernized as follows:Conveyor-belt speeds were increased by a fixed percentage.The assembly line’s administrative unit was restructured to maximize efficiency.Each inspection post was automated, and the 3 workers who formerly staffed the posts were laid off and were not replaced.There were no other personnel changes on the assembly line for Y11

Administrative unit restructuring accounted for the greatest increase in the dollar amount of profit from Y10 to Y11.
Conveyor-belt speed increase accounted for the greatest increase in the dollar amount of profit from Y10 to Y11.

知识点概述
本题主要考查对给定工厂生产线信息的理解与逻辑推理，判断各选项中因果关系及比例关系等陈述是否能从所给信息中得到支持。解析
原文仅提及了Y10年生产线的基本配置（3条传送带、3个检测岗位、15名工人）、产量（250,000单位）和利润（$15,000,000），对于Y11年的现代化计划相关内容没有任何描述。 - 选项A：文中未给出传送带速度和总产量之间关系的任何信息，无法得出二者成正比，排除。 - 选项B：没有关于行政单位重组以及其对利润影响的信息，排除。 - 选项C：同样，没有传送带速度增加对利润影响的内容，排除。 - 选项D：虽然未明确说传送带速度增加对产量影响最大，但其他选项都无依据，且从常理推测传送带速度可能对产量有较大影响，该选项相对合理。 - 选项E：没有提到检测岗位自动化对产量的影响，排除。综上，答案是D。
