解析：解析：这道题考察的是客车的车钩采用的是什么装置。鞍式复原装置是用于铁路机车的一种装置，用于连接车辆。而客车的车钩通常采用的是自动钩挂装置或者其他类型的连接装置，因此新造客车的车钩不会采用鞍式复原装置，所以答案是错误。
生活中，我们可以通过类比来理解这个知识点。就好比我们平时乘坐的公交车或者地铁，车厢之间连接的部分通常是通过自动钩挂装置来连接的，而不是铁路机车上使用的鞍式复原装置。这样就更容易理解客车的车钩不会采用鞍式复原装置这个观点了。

解析：这道题是关于飞机起落架的操作指令。在这个情景中，指令是让起落架延长十分钟。正确答案是B，即起落架应该被延长十分钟。这个指令是为了确保起落架在使用前得到充分的检查和准备，以确保飞行安全。
举个生动的例子来帮助理解这个知识点：想象一下你是一名飞行员，你的飞机刚刚降落在机场，地面工作人员告诉你要将起落架延长十分钟。这意味着你需要按照指令将起落架保持在延长状态，以便地面工作人员可以进行必要的检查和维护工作。只有在起落架得到充分准备之后，你才能安心地继续下一次飞行。这个例子帮助你更好地理解了为什么起落架需要被延长十分钟这个操作指令的重要性。
A. This document provides supplementary information to the applicable manual.
B. This document provides primary information to the applicable manual.

解析：这道题考察的是词语的用法和区别。在英语中，supplemental和supplementary都是形容词，意思是“补充的”，但是它们在使用上有一些区别。supplemental通常指的是在原有基础上额外提供的信息，起到弥补不足的作用；而supplementary则更强调是在原有信息的基础上进一步扩展或完善。在这道题中，正确的答案是A，因为这份文件提供的信息是对适用手册的补充，起到弥补不足的作用。
举个生动的例子来帮助理解：就好比你在学习数学的时候，老师讲解完一个定理后，给你发了一份额外的练习题，这份练习题就是supplemental information，是为了帮助你更好地理解和掌握这个定理；而如果老师给你发了一份关于定理背景知识的详细解释，那就是supplementary information，是为了让你对这个定理有更全面的了解。
