这题考查倍数的表达法，这里使用了“倍数+the+n+of”的表达法，句意是:伦敦塔的高度是教堂塔的3倍。

London has the tower of Big Bang.

这种用法是对的
用英语表达“A 是 B 的 N 倍长（宽,高,大,重等）”,“A 比 B 长（宽,高,大,重等）N 倍” 或“A 的长度（宽度,高度,大小,重量等）是 B 的 N 倍”,可用下列几种句型.
1.“A + be + 倍数 + as + 计量形容词原级 + as + B”.
This tree is three times as tall as that one.
这棵树是那棵树的三倍高.
His father is twice as old as he.
他父亲的年纪有他两倍大.
2.“A + be + 倍数 + 计量形容词比较级 + than + B ”
The Yangtze River is almost twice longer than the Pearl River.
长江差不多比珠江长两倍.
The dictionary is exactly five times more expensive than that one.
这本字典比那本恰好贵5倍.
3.“A + be + 倍数 + the + 计量名词 + of + B ”
The newly broadened square id four times the size of the previous one.
新扩建的广场是未扩建时的四倍大.
4.“The + 计量名词 + of + A + be + 倍数 + that + of + B ”
The size of the newly broadened square is four times that of the previous one.
新扩建的广场为以前的四倍大.
5.其它I‘m twice/ double his age.我的年龄是他的两倍.

The price of TVs are twofold（ adj.两部分的,双重的） down over these years.
近几年来,电视机的价格下降了两倍.
一、用times表示倍数（一般限于包括基数在内三倍或三倍以上的数.表示两倍的数,一般twice.）.其句型有：
1.times＋形容词（副词）比较级＋than...
This hall is five times bigger than our classroom.这个大厅比我们的教室大五倍.（是我们教室的六倍大）

2.times＋as＋形容词（或much）或副词原级＋as...

Asia is four times as large as Europe.亚洲的面积是欧洲的四倍.
Ten is twice as much as five.十是五的两倍.

4.times＋more＋名词（可数,不可数）＋than...

6.times＋over＋被比对象表示“增加……倍”.如:

7.times＋thatof＋被比对象“是……倍”.如:

二、用...％（percent,per cent）＋up on＋被比对象

The industrial output of last year in our factory was 250％ up on that of 2000.我们工厂去年的工业产量比2000年增加了 250％.（或增加两倍半）
三、用double表示倍数
1.double作形容词,“两倍的”.如:
The production is now double what it was ten years ago.现在的产量是十年前的两倍.
2.double作动词,“是……的两倍”.如:
The output has been doubled in the past five years.过去五年中产量翻了一番.

city's

1.those常用作后接定语从句中关系代词的先行词,they,them则不可.he had conquered是定语从句,因为关系代词作conquer的宾语,所以省略了.这里those相当于people.
2.it is one thing...it is another...固定搭配.意为：.是一回事,.又是另一回事.
3.这里比较的对象是libraries,不是today和past.所以要用代词those指代libraries.

those he had conquered.(不是conqueror)
因为those这里指代那些人,所以不能用其他几个选项
