单项选择题 Industrialization came to the United State after 1790 as North American entrepreneursincreased productivity by reorganizing work and building factories. These innovationsin manufacturing boosted output and living standards to an unprecedented extent; theaverage per capita wealth increased by nearly 1 percent per year―30 percent over(5) the course of a generation. Goods that had once been luxury items became part ofeveryday life. The impressive gain in output stemmed primarily from the way in which workers madegoods, since the 1790's, North American entrepreneurs―even without technologicalimprovements―had broadened the scope of the outwork system that mace manufacturing(10) more efficient by distributing materials to a succession of workers who each performed asingle step of the production process. For example, during the 1820's and 1830's the shoeindustry greatly expanded the scale and extend of me outwork system. Tens of thousandsof rural women, paid according to the amount they produced, fabricated the 'uppers' ofshoes, which were bound to the soles by wage-earning journeymen shoemakers in dozens(15) of massachusetts towns, whereas previously journeymen would have made the enureshoe. This system of production made the employer a powerful 'shoe boss' and erodedworkers' control over the pace and conditions of labor. However, it also dramaticallyincreased the output of shoes while cutting their price. For tasks that were not suited to the outwork system, entrepreneurs created an even(20) more important new organization, the modem factory, which used power-driven machinesand assembly-line techniques to turn out large quantities of well-made goods. As earlyas 1782 the prolific Delaware inventor Oliver Evans had buiit a highly automated,laborsaving flour mill driven by water power. His machinery lifted the grain to the top ofthe mill, cleaned it as it fell into containers known as hoppers, ground the grain into flour,25) and then conveyed the flour back to the top of the mill to allow it to cool as it desendedinto barrels. Subsequently, manufacturers made use of new improved stationary steamengines to power their mills. This new technology enabled them to build factories in thenation's largest cities, taking advantage of urban concentrations of inexpensive labor,good transportation networks, and eager customers. What is the passage mainly about?A．The difficulties of industrialization in North AmericaB．The influence of changes in manufacturing on the growth of urban centersC．The rapid speed of industrialization in North AmericaD．Improved ways of organizing the manufacturing of goods

单项选择题 甲从某厂退休返乡后，决定利用曾在红星公司工作多年的优势，与村民乙、丙商量合伙开办出口台布的加工业务，约定甲出资1万元，负责联系业务，乙、丙各出资4000元，负责组织村民干活并进行技术指导。三人起草了一份协议，但尚未签字。当年底，完成多批加工任务，获得利润5万余元，三人按约定比例进行了分配。次年，因赶上农活忙季，人手少，台布出现质量问题，约购货方红星公司造成3万余元的经济损耗。红星公司要求甲、乙、丙赔偿，乙、丙称自己是受雇于甲，不能承担责任，于是甲向红星公司赔偿了全部损失。根据以上案性。请回答以下问题。甲、乙、丙三人之间的关系应如何认定？
