The term 'Did a Lawn Chore' refers to four different tasks that can be done to maintain a lawn. The first task is mowing, which involves cutting the grass with a lawnmower. The second task is watering, which involves providing water to the lawn to keep it healthy. The third task is liming, which involves adding lime to the soil to reduce acidity and improve fertility. The fourth task is hosing, which involves using a hose to clean the lawn and remove debris. All of these tasks are necessary for keeping a lawn in good condition.
