請問一題

This scenario begins with the planting of hyper accumulating species in the
target area, such as an abandoned mine or an irrigation pond contaminated by
runoff.


題目是
10. Which of the sentences below best expresses the essential information in
the highlighted sentence in the passage? Incorrect choices change the meaning
in important ways or leave out essential information.

1. Before considering phytoremediation, hyper accumulating species of plants
local to the target area must be identified.

2. The investigation begins with an evaluation of toxic sites in the target
area to determine the extent of contamination.

3. The first step in phytoremediation is the planting of hyper accumulating
plants in the area to be cleaned up.

4. Mines and irrigation ponds can be kept from becoming contaminated by
planting hyper accumulating species in targeted areas.

答案是(3)

我不懂的是

這些植物被種植就是為了要吸收有毒重金屬汙染

所以才要放在 abandoned mine 或 irration pond contaminated

可是第三個答案說

第一步要種植的區域要 clean up

是我誤會答案嗎?
