Task: Question Answering
Input (English): Passage: Cleaning a shower sucks . Why does it dirty if all you do is clean yourself in it ? The reason why is that the soap and the hard water creates this ugly film that makes it look dirty .  Most people 's water is hard .  In soft water , soap suds up and it does n't stick so bad to the walls . Can never really clean it unless use chemicals to break up the soap scum . Even with the cleaner called `` BlastOff '' it does n't fully remove it unless use the white Mr. Clean sponge in tandem with BlastOff .  The white sponge with the BlastOff spray works better than the pumice that is used by scraping the tiles . Unless it iodine stains -- then have to use something completely different and I forgot the name of the brand that removes iodine . Removing iodine stains by spraying and leaving there over night , it will be gone , but only in the places where it dripped down and have to use the entire bottle all at once . Question: How can tell they have hard water? Option1: clean shower Option2: when the soap creates and ugly film
Output (English): when the soap creates and ugly film
