Answer 1

先行词都要放在引导词前面。
whose具有兼作who和 which的所有格的双重功能，既可指人，也可指物。

Mr Brown has written a novel whose name（=the name of which）I've completely forgotten．布朗先生写了部小说，其书名我完全忘了。
注意：下列情况whose与of which切不可混用
1.of which同数词或代词（如some，many，little等）连用表示部分与整体关系时，通常不可用 whose。
Mr White wrote many articles，some of which were translated into Chinese．怀特先生写了不少文章，其中一些译成了中文。
In Barcelona the Chinese team got 16 gold medals，12 of which were won by women．在巴塞罗那中国队获得16块金牌，其中12块由女运动员赢得。
2.of which修饰定语从句中的主语，是表示同位关系的代词both，all等时，切不可用whose
He has some novels，all of which are written in Russian．他有一些小说，都是用俄文写的。

Living in the Central American desert has its problems,of which obtaining water is not the least.
这里of which修饰problems，problems放在其前面,没有你说的那种情况。

The journey around the world took the old sailor nine months,of which the sailing time was 226 days.
这里of which修饰months，months放在其前面,没有你说的那种情况。
