Example Input: [header] How to fist bump [title] Ball your hand up into a fist. [step] Press the tips of your fingers into your palm so that your hand makes a fist. This will be the position that you keep your hand in for the bump. <sep> (A) Hold the fist up high enough to extend your palm to one side. Bend your wrist so that both fingers are pointing out, with the whites of your knuckles showing. (B) [title] Put your fist out in front of you. [step] Place your fist in front of your body with your knuckles facing up. (C) Make sure your palm looks nice and flat. Ideally, this hand should be neither thicker nor thinner than your fist. (D) [substeps] Whether you're with friends or with an opponent, the fist looks like a punching bag in a gym. The knuckles, the tips, and thumb look like a regular ring finger.
Example Output: B

Example Input: [header] How to choose the best hula hoop (adult sized ) [title] Measure your height from the floor to your belly button. [step] This measurement will then help to determine the diameter of the hoop you should purchase. The hula hoop, when resting vertically on the ground, should reach somewhere between your waist and mid-chest. <sep> (A) [substeps] Example: if your height is 36 inches (76 "), then 118 inches (77 ") would be the minimum height. For kids, this would be 24 inches (76 "). (B) This is your base diameter measurement and can be adjusted slightly depending on your size and experience level. [substeps] For example, most adults will begin with a hula hoop between 40 and 44 inches in diameter. (C) [title] Find a hoop that you know you can balance on. [step] This will improve the stability of the hoop and prevent you from accidentally dropping the ball while on it. (D) Your waist should be about an eighth of an inch shorter than the hoop. You should also measure your waist from hips to ankles, and to knees with a ruler or measuring tape.
Example Output: B

Example Input: [header] How to dispute a lot line survey as a defendant [title] Hire a lawyer. [step] As soon as you are served with the plaintiff's lawsuit, you should strongly consider hiring a qualified real estate lawyer. Specifically, look for a lawyer with experience litigating property boundary disputes. <sep> (A) [substeps] While you are at the site, ask if your city or county bar association has a lawyer you can use. Alternatively, visit the website of each city or county bar association. (B) If you absolutely must hire a lawyer, then find one that specializes in property, design, or engineering. A general rule of thumb is to hire an experienced real estate lawyer, preferably who can provide personal experience to expert witnesses. (C) [substeps] Never hire an attorney who does not work for the state or federal government. Only hire lawyers who have experience representing local or state judges and arbitrators. (D) A lawyer will help you negotiate a settlement, effectively cross-examine plaintiff witnesses, and retain a quality expert of your own. Start the search process by asking friends and family for recommendations.
