Passage: Today I decided to clean my home . The floors were dusty , so I went to the closet and took out the broom and dustpan . I cleaned the floors using a sweeping motion , making sure to check in the corners , behind the couch and chairs , and under the rug for dirt and dust . I used the broom to sweep the pile of dust into the dust pan . I carried the full dust pan to the garbage , and emptied it into the garbage . Then I took the broom and dust pan back to the closet , and hung them back on their hook . I took the garbage out of the garbage can , tied up the strings , and carried it outside to the dumpster . I washed my hands and I felt good that my house was clean . Question: When did they place the garbage bag inside the dumpster? Option1: Before they took out the broom. Option2: after tieing up strings
Output:
after tieing up strings
