C. threat, after losing their habitat, to native species of plants and animals and also to maintenance of biologically diverse ecosystems

E. threat to native species of plants and animals as well as to maintaining biologically diverse ecosystems, after losing their habitat

Answer: A

想問選項 C 跟E 的habitat 是可數N 那沒有加S也算是錯嗎?
還有C 的and also to 算是破壞平衡的結構囉?

(C) 改變句意:不是 invasive plants lose habitat(s). habitats 單複數文法上都對. also 沒有破壞平衡,是多餘.
原句的意思是"侵入性植物是本地植物失掉棲息地之後的第二嚴重威脅"
