知音I閱讀測驗 alien invasive species - 英檢

有一題我不是很懂為什麼 想請教各位

如果有人有做過可以回答一下嗎

謝謝

The seriousness of the problem in this part of the word, where native species

are gradually being out-competed and replaced by the invaders, has become so

pronounced that marine biologists have given intrude who come into this

particular area by this particular means their own special classification.

They are referred to as "lessepisan species".


題目

According the passage, which of the following can be said about lessepsian

species?

A They damage any envionment that they enter

B They are only found in the Eastern Medierranean.


我的問題是再上面那段應該是在強調

由"being out-competed and replaced by the invaders" 可知道

外來物種會破壞當地的原生性

也就是會使當地物種

失去生存的競爭力

只是因為外來物種在Medierranean發現

生態學家只是把它分類命名為 "lessepisan species"

那為什麼答案會是 B 呢

謝謝各位~
