"The evidence that the flower in the greenhouse failing to endure any storms indicates that kids should never be spoiled too much."
This sentence is the answer of an translation question which I found in a English exercise book. The question required me to translate a sentence from my native language to English. And I doubt the "failing" in this sentence, I think there must be something wrong.
Is this sentence right or wrong? If it is wrong, could you show the right one? Thank you very much!
