Example Input: [header] How to restore a boat [title] Make a plan. [step] Plan your work by breaking everything down into sections, like chapters in a book. Chapter one is planning. <sep> (A) This is where your business development can start. Analyze the navigation board, take all the necessary materials and then create your grand vision. (B) This step is not yet complete, so you need to prioritize moving toward part 1 of the project. This will help you tackle all your major projects faster, so that you can review your own work by taking each section and remembering to include the steps in that section over time. (C) The next phase might be stripping the boat in preparation for the work. [title] Prepare a work site, gather tools and supplies, carve out a dedicated time on a regular basis with your schedule, consult experts in the field, and also outsource certain components as needed to certain experts. (D) Plan your time on your own to avoid confusion and frustration with each chapter. Be sure that you aren't scrambling for ideas as you go forward so that you don't get overwhelmed by too many ideas.
Example Output: C

Example Input: [header] How to determine who has right of way [title] Come to a complete halt at a stop sign or red light. [step] At a stop sign, come to complete halt for about 2 seconds or until vehicles that arrived before you clear the intersection. If you're stopped at a red light, proceed when the light has turned green. <sep> (A) This will give you enough time to catch the light and clear the intersection. [substeps] Vehicles behind or behind you may not brake. (B) This blocks oncoming cars from passing you. [substeps] If in doubt, you can also tell if you're going too fast by looking ahead at the tires of that car. (C) If you are stopped before a red light signals for another vehicle, you're on your own. [substeps] This means every car crossed before you has passed, and every vehicle in the intersection has stopped before you. (D) If the intersection has a white stripe in your lane, stop before this line. [substeps] If you have a stop sign, but the street you're crossing does not have a stop sign, wait until all traffic has cleared before crossing the intersection.
