Complete the following sentence with a (compound) word derived from the one(s) given in bracket.
When we are working out the plan, we should take （ ） into consideration. (impossible)
【正确答案】：IMPOSSIBILITY
【题目解析】：
根据前文take是动词，空格处应该填名词形式，take sth. into consideration把...考虑在内，impossible的名词形式impossibility不可能性，且符合句意。句意：我们在制定计划时，应该把不可能性考虑在内。
