国土资源部2012年4月28日发布的全国土地石漠化报告显示，我国石漠化的总面积达到了11.35万平方千米，每年因为石漠化损失的耕地面积为30万亩。石漠化是在喀斯特地貌基础上形成的一种荒漠化的现象，简单来说就是土地逐渐被石头占据。90%的石漠化地区集中在云贵高原地区。下图为云贵高原形成与发育过程示意图，读图回答小题。 石漠化地区集中在云贵高原地区的主要原因是（）。①降水集中②不合理的农业活动③土层薄，水土易流失④地表径流丰富
One hundred and fifty years ago, the position of women in the U. S. society was very different【C1】______their position today. At that【C2】______, women were completely subordinate to【C3】______.

背景材料：几位同学拟参照下述资料用实验方法测定阿伏加德罗常数：硬脂酸溶于苯，难溶于水，用一定量的硬脂酸配制一定体积的硬脂酸的苯溶液。在圆形玻璃水槽中盛半水槽水，用长尖嘴胶头滴管把硬脂酸的苯溶液逐滴滴到水面上，液滴在水面扩散，苯挥发，硬脂酸分子以亲水基团朝下、憎水基团朝上排列在水面上。滴到水面的硬脂酸的苯溶液足够多时，在水槽的整个水面上形成一层单分子膜。测定所形成的单分子膜的面积，利用硬脂酸分子截面积A的数据（2.2×10cm），就可以计算出单分子膜中硬脂酸的分子数。再依据形成单分子膜的硬脂酸质量和分子数，通过简单换算即可确定阿伏加德罗常数的值。请帮助研究小组完成实验设计中需要解决的问题：
