Motor cars were first made in England just before 1900. The parts for the bodies and engines were hand-made and the cars were built from these. One at a time. This took a long time, and the cars cost a lot of money. Then a quicker and cheaper way of making cars was found. Instead of making all the parts at their own works, some car factories asked other factories to make some of them. All the parts were then fitted together in the car factories.

Modern car-making factoriess are so large that each one is really a lot of factories close together. Each workshop makes some parts. The pieces of a car body are joined together by welders(电焊工) . All the bits and pieces that make up each car are collected and put ready for the assembly line(装配线) , where they are fitted together.

【背景资料】某工业厂房车间3层,7度抗震设防。高度20m,长度为70m,独立基础,结构形式为砌体承重结构。在建成使用几个月后发现底层局部地面呈锅底形下沉,砼地面脱落、开裂,后来又发生墙体开裂,裂缝呈正八字裂缝和斜向裂缝,裂缝宽度达1mm~2mm,一般分布在底层中下部,且首先在窗对角突破,严重影响了建筑物的使用和工厂面貌,给工厂造成了重大的经济损失。经翻阅资料发现,该仓房实际上处于软弱土层,且为淤泥质土,地勘报告不准确;最终认定是由于地面不均匀沉降造成的危害。

请根据背景资料完成以下选项
