答案是b A里面的it指代不了前面的chambers; B中用了them 所以正確
代詞和性別要一致 him/her/it
3.2 指代的邏輯語義
① 指代內容必須存在，且以名詞的形式出現
The park rangers discussed measures to prevent severe wildfires, which would be devastating to it.
這里的park充當的是形容詞;所以不能做IT的先行詞;應把句子改成The rangers discussed measures to prevent severe wildfires, which would be devastating to the park.
The energy source on Voyager 2 is not a nuclear reactor, in which atoms are actively broken apart; rather a kind of nuclear battery that uses natural radioactive decay to produce power.
(A) apart, but rather
(B) apart; it is that of
A 正確;B的話， that of沒有指代對象
d. exhibit and thereby activate
e. exhibit, and it will activate
A正確; B中的it無指代 而且這里的touch和activate做并列，出來的動作都是visitors來發起;所以要用兩個動詞做并列。 It在這里加的不合理。
② 代詞不能指代出現在前面介詞短語中的名詞
Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
③ 同一句話中相同的代詞必須指代相同的事物
As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with such vision.
a. A baby emerges from the darkness of the womb with a rudimentary sense of vision that would be rated about 20/500; an adult with such vision would be deemed legally blind
b. As a baby emerges from the darkness of the womb with a rudimentary sense of vision, it would be rated about 20/500, or legally blind if it were an adult with such vision.
A 正確; B的話，兩個it并沒有一個明確的指代，而且先行詞有兩個;所以會造成語義指代歧義的可能
④ 因為比較結構比較對象的一致性，有時用that of 指代前文出現的對象
Laos has a land area about the same as Great Britain but only four million in population, where many are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
a. about the same as Great Britain but only four million in population, where many
b. comparable to that of Great Britain but a population of only four million people, many of whom
B中that of正確;土地和土地比; A中土地和國家比
that或those表明新copy的時候一定前后完全一致(包括單復數)，否則需要重復先行詞。
EG：Her company is outperforming those of her competitors.錯，those與company不一致，應將those替換為companies.
