1）翻译下面的句子：
他的决定从经济上完全可以理解，但从道德上很难成立。
His decision can be justified from an economic aspect, but can hardly be justified morally.
（参考翻译：His decision can be justified from an economic point of view but can hardly be morally/ethically justified.）
2）结合自己的生活、学习、工作、兴趣等，先想象在什么语境下会用到这个表达，然后再进行造句。
场景：尽管这种模式看似有很多问题，但是能开展那么多家分店证明它没问题。
造句：Though the model has many bugs, so many branches justify its success.
