《莱因德纸草书》（Rhind Papyrus）是世界上最古老的数学著作之一．书中有一道这样的题目：把100个面包分给5个人，使每个人所得成等差数列，且使较大的三份之和的 $\frac{1}{7}$ 是较小的两份之和，问最小一份为（  ）

阅读下列材料，回答相关问题：

材料一：在地理大发现前，欧洲人对生活在神秘遥远的东方人民深感离奇莫测，传奇虚幻令人惊愕：如说恒河源头的印度人吃蛇，而且能活到400岁；有些人生来只有一条腿，但行动灵巧……甚至认为印度洋的土地上是一个由人和动物两类怪物组成的世界。

材料二：直到15世纪，欧洲的世界地图也很简单：基督耶稣高高在上俯视世界，从诺亚方舟洪水退却之后，诺亚三个儿子分别居住欧、亚、非三洲成为各洲始祖。地图上用圆规画出网状，网状内有代表城市和王国的旗帜与城堡，所谓“世界”即以地中海区域为主要范围的世界。

材料三：美洲和东印度航路的发现扩大了交往，从而使工场手工业和整个生产的发展有了巨大的高涨。从那里输入的新产品，特别是投入流通的大量金银（它们根本改变了阶级之间的相互关系，沉重地打击了封建土地所有制和劳动者），冒险的远征，殖民地的开拓，首先是当时市场已经可能扩大为而且规模愈来愈大地扩大为世界市场——所有这一切产生了历史发展的一个新阶段。
