Answer:
Jerry owes a duty of slight care, in regards to the parakeet
Explanation:
In this situation since this is a bailment for the sole benefit of the bailor, Jerry owes a duty of slight care, in regards to the parakeet. This refers to the fact that Jerry has a legal obligation to adhere to the rules set forth by Tom and demonstrate a level of reasonable care when performing these rules/tasks, since not doing so may bring harm to the parakeet or Tom. Which by neglecting to make sure that the cage was closed properly the bird is forever gone and Tom is hurt both financially and emotionally from the parakeets loss.
