Teacher: In this task, you're given a context passage, followed by a question that needs to be answered. Based on the paragraph, you must write unambiguous answers to the questions and your answer must refer to a specific phrase from the paragraph. If multiple answers seem to exist, write the answer that is the most plausible.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Tracy slept awkwardly on their new bed and was having some pain, so Tracy cracked her neck.
Question: What did Tracy do with her neck?
Solution: crack her neck
Reason: The output phrase perfectly answers the question and is explicitly mentioned in the passage as well.

Now, solve this instance: I was in my kitchen about to cook dinner for my boyfriend and myself. We were going to have steak and some sauteed vegetables. I had already put the steak in the oven and was about to begin sauteing 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?
Student:
They started chopping the vegetables after they placed the steak into the oven.
