Task: Question Answering
Input (English): He was left home with my mom and then transported up here after one week , in a quart Chinese - food container with air holes in the lid . This container was in a padded box with no lid , which was then sandwiched inside a bigger box between the front seat and the dashboard . He literally didn't move except for the relative rocking of the car as it moved , so I don't think that it stressed him all that much . My friend was careful to keep the temperature in his car above 70 the whole time he was driving up here ( much to his chagrin , as it was pretty warm , haha ) . 
Question: What may have caused you to leave him in a Chinese - food container ?
Output (English): I needed something to store him in .
