Why is “be evaluated” wrong for second blank?
Why do you think its right ?
if species even though exotic are considered to be dangerous then eradication measures may be evaluated.
Why is it wrong?
What your reasoning for saying that we have got these measures already in place ?
Notice the then before the expensive
What is the role of “Then” in this statement?
From the question , the acceptance of species by scientist is not an easy task (why? because so many things have to be taken into consideration: expense,labour, ecological eradication ) . Also, if its exotic (rare) and is potentially harmful then the above consideration comes into actions (or follows)
Guess for blank(i) - not an easy task
Guess for blank(ii) - comes into action or follow

Understood. Thanks a lot Kremlin.
What is the meaning of “may be evaluated” ? (Just for knowledge)
it can mean maybe analyzed or maybe be gauged or maybe be updated depending upon the context.
