Task: Question Answering
Input (English): Passage: Every few weeks , the grass in my yard grows too high and I need to mow it to keep it looking nice and neat . Yesterday , I had to mow the lawn again . Some people have lawn mowers you can sit on and ride , mine is a push mower since my lawn is n't very big , and I like the exercise . I checked to make sure there was enough gas in the mower , and pulled the string to start the engine . Being careful , since the mower has very sharp , fast-moving blades underneath , I went in a straight line from one end of the yard to the other . After I finished mowing the lawn , I made sure to put my lawn mower back in the shed where it belonged , and enjoyed a large , cold glass of lemonade , since lawn mowing is hard work . Question: When was all the grass cut short? Option1: every day Option2: yesterday
Output (English): yesterday
