Read the following context and choose the best option to answer the question.
Context: I bought her a special sleeping bag ( hot pink outside , lime green floral print inside ) , so that we could train her to use it as her travel bed . It did n't work very well . The only way we got her to sleep at all was to lay with her in the cramped floorspace and sing her to sleep . This took more than an hour for each nap & bedtime .
Question: What may have been your reason for buying the sleeping bag ?
Options: 
- She wanted that sleeping bag because it had a special hot pink color .
 - She needed somewhere to rest when she travelled .
 - I did n't want to sleep on the floorspace anymore .
 - I needed somewhere to rest when I travelled .


She needed somewhere to rest when she travelled .
