Example Input: [header] How to handle a kitten [title] Be gentle and patient when picking up the kitten. [step] Kittens are very small and fragile, so make sure you're using a very light touch and gentle care. If the kitten shows signs that it doesn't want to be touched, like avoiding your touch or running from your hand, leave it alone and try again at a later time. <sep> (A) [title] Handle your kitten slowly and with caution. [step] Depending on when you picked the kitten up, you may need to start with a short cuddle, and gradually move from there. (B) [substeps] Watch out for the mother cat, who may not want anyone handling her kittens. She may bite or scratch people to prevent them from touching the kittens. (C) Talk to a familiar person or pet when picking up the kitten if you think you can cut away some of its protective protective bubble. [title] Avoid picking up the kitten from its mother. (D) Just imagine that you were picking your kitten up by its neck, holding one hand over its head, and guiding its ears, not gently placing one hand on its head. That gives the kitten shock, so be careful of hurting the kitten.
Example Output: B

Example Input: [header] How to set up a caique parrot habitat [title] Choose a large cage. [step] Although the caique is a medium-sized bird, it needs a great deal of space. Select a cage that can accommodate this energetic parrot. <sep> (A) New cages tend to have more cages that are more hearty and safe, as these should not be bigger than 20 square feet (36 square meters) on all sides. If you're keeping a senior parrot, choose a caique that has built in cage work. (B) When it comes to caique cages, bigger is always better. [substeps] The smallest cage for a single caique should be 24 x 24 x 24 inches (60 x 60 x 60 cm). (C) The standard size for caique quarlings are 4 inches (10 cm) and five feet wide. Add a basking bulb, separate the block of wood with coarse wood shavings and place the bottom on a cooled to room temperature examination table. (D) For a more fluid experience, a small cage that you can comfortably surround your bird in will help to make the experience more comfortable. [substeps] A second enclosure can provide the environment your bird will be inhabiting without having to create a constant environment, changing its structure and its oxygen levels.
