Input (English): Passage: Yesterday my toilet got clogged . I 'm not sure why it happened , but I knew some of the things I needed to do in order to fix it . Firstly , I traveled to the store and bought a plunger . Afterwards I drove back home and tried to use my new plunger on the toilet . I placed the plunger over the toilet drain , pressed down , and then began to pump , trying to get whatever was clogging the drain to be dispersed . Luckily , after a while of pumping , I heard the toilet water begin to drain . Luckily , I had been able to fix the clog by simply buying a plunger and using it on the toilet . I was glad that I managed to avoid calling a plumber by simply doing the work myself . Question: How did the toilet get clogged? Option1: They don't know Option2: by rubbing the toilet
