Task: Question Answering
Input (English): I was in my kitchen about to cook dinner for my boyfriend and myself. We were going to have steak and some sautéed vegetables. I had already put the steak in the oven and was about to begin sautéing the vegetables. I pulled a zucchini and a yellow squash out of the refrigerator and placed them on my cutting board. I grabbed a knife from our knife block and began to cut the vegetables. I first cut them into equal sized rounds, but those would be too big to bite so I decided to cut them again. I cut each round in half so it was in the shape of a semicircle. All of my vegetables were cut, but I decided to put one more vegetable in with the mix. I pulled some grape tomatoes out of the refrigerator and put about ten of them on my cutting board. I cut them all in half and poured them into the pan along with my yellow squash and zucchini. 
Question: When did they start chopping?
Output (English): They started chopping the vegetables after they placed the steak into the oven.
