Example Input: [header] How to wear a graphic tee [title] Wear your tee under a jacket. [step] For a casual, yet tailored look, try wearing your tee underneath a blazer. The blazer should fit you well and have a certain amount of structure to it. <sep> (A) Try half-tucking your tee into your pants for a super cool, slouchy look. [title] Pair your tee with high-waisted shorts. (B) [title] Choose a graphic tee that matches the slimmest part of your body. [step] Vintage t-shirts and jerseys are the most common graphic tees. (C) Try on the blazer and pull it down at the waist to see whether it feels snug at the top. [substeps] A professional would be happy to accommodate your slimmer waistline. (D) If you are not feeling confident enough to wear your work shirt in a more casual way, then go ahead and throw the tee in the garbage. [substeps] Choose a solid colored tee for a more polished look, but if you can still slip it in without distortion, wear it under a gray top.
Example Output: A

Example Input: [header] How to make a sleeveless shirt [title] Choose which shirt you would like to make sleeveless. [step] Almost any shirt lends itself to becoming sleeveless, but there are some common options. [substeps] T-shirts old blouses long-sleeved shirts [title] Turn your shirt inside out and lay it on a flat surface. <sep> (A) [step] Cut along the fold so the front of the shirt is close to the seam. [title] Lay a piece of duct tape across the seam. (B) [step] Roll up the sleeves so that they extend past your elbow and onto your shoulder. If you can, collect some excess material in a bag or pick it up from the floor and then place it back over your shoulder. (C) [step] This can be a small table, a textbook, or a pile of paper. Because this is the shirt with the sleeves rolled off to the side, it should be close to the outside of your shirt. (D) [step] It is important that the surface is flat so that you cut the shirt evenly. [title] Cut strips into the sleeves, perpendicular to the seam.
Example Output: D

Example Input: [header] How to remove cat spray [title] Blot the urine right away. [step] If you see your cat spray in the house or find a wet urine stain, blot the spot with a clean towel immediately. This will soak up as much urine as possible, diminishing the possibility of the pee soaking into your rug or upholstery. <sep> (A) [substeps] Do not use the towel on a wet stain. [title] Flush the stain with hot water in the sink. (B) [title] Use water and a few drops of soap to dilute the damp spot. [step] Get a bowl of warm water, and put a few drops of mild soap in it. (C) [substeps] It may take several days before your cat stain is completely gone or has been removed. The easiest, but least effective way to spot a wet spot, is to blot the urine with a clean, dry towel. (D) [substeps] If the urine stain shows up somewhere else after it has soaked, you'll want to dry the area immediately with a towel. Let your rug dry until the urine has completely dried.
