Example Input: [header] How to remove paint from a car exterior [title] Park the car on top of a large tarp or drop cloth to contain the old paint. [step] The old paint should be disposed of instead of letting it contaminate the ground. If an open area is not available, park the car inside a garage, but open all of the garage's windows and doors for ventilation. <sep> (A) Cover objects inside the garage to protect them from the paint dust. [title] Use masking tape to cover the areas of the car that won't be sanded. (B) Alternatively, use a flashlight to check beneath the tarp. [title] Use an old baseball bat, crowbar, pry bar, or other large object to push the old paint off of the vehicle. (C) [title] Wipe the paint with a wet cloth, a roller wrap or an old towel to protect it from oil and water. [step] The paint is likely to collect on these cloths and make them easier to clean as they are removed. (D) If your garage is not well ventilated, a ventilation device will block your windows when the old paint has dried to a mud-like consistency. [title] Pour a small amount of vinegar into a small bucket.
Example Output: A

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.
Example Output: B

Example Input: [header] How to deal with an eating disorder during pregnancy [title] Talk to your obstetrician about your history of eating disorders. [step] Resist the urge to conceal your condition, even if you feel embarrassed or ashamed. Your obstetrician is one of your best resources during this time. <sep> (A) She can check for any abnormalities and make a recommendation for a treatment that suits your needs. [substeps] Stay with your doctor or a nurse if you feel you have a problem. (B) [substeps] Your doctor may recommend a physical examination to confirm that you are not suffering from an eating disorder and is not on any medications or treatments. This will also help your doctor decide if you have underlying medical issues and if that is an ideal course of treatment. (C) [substeps] Sometimes, eating disorders, such as bulimia or anorexia, can develop for the first time when you are pregnant. If you do not have a history of eating disorders but are worried about your weight or eating habits, tell your obstetrician. (D) Answer all of her questions as openly and honestly as possible, whether you're diagnosed with some type of eating disorder or not. If you have regular meetings with the doctor or ob/gyn, discuss your reasons for keeping your disorder hidden or figuring out an alternate treatment plan for those issues.
