Example Input: [header] How to show a girl that you care (for guys ) [title] Get to know her. [step] If you're in school together, talk to her in class. If you have mutual friends, talk to her whenever that group gets together. <sep> (A) Most guys just like girls that have something in common. Being more than friends means more opportunities to develop interests. (B) If you don't, ask if there are other friends you can hang out with. Though making contact is difficult, if you're hanging out as a group, you can start if you form a strong bond with her. (C) You don't have to make a big deal about it-just say hello and smile at her. Ask her how she's doing, and strike up a conversation. (D) Talking with her in front of other guys is a great way to showcase your boyfriend's love for her. She'll start to see your declaration as an admission of love and to get to know you better, too.
Example Output: C

Example Input: [header] How to create a romantically decorated room [title] Clean out all clutter, distractions, and signs of work or chores. [step] Before actively adding romantic decoration, you need to take away things that detract from the romance of the room. The best way to do this is to clean up the room and remove things that get in the way of romance. <sep> (A) [substeps] Get rid of old papers, magazines, shoes, or anything by knocking them over and throwing them in the trash. The same idea goes for candles, jam jars, or vases. (B) Keeping the space tidy and ready for romance is probably the best method, but it is not always possible. [substeps] Get rid of your desk or supplies. (C) Stand in the room and look around at what is present. Let your eye linger on things that seem overly business-like or seem to represent work and responsibility. (D) [substeps] Take down anything that gets on the floor, encourages the furniture to move around, or makes the room feel creepy. Remove everything that is on the floor that doesn't belong anymore.
Example Output: C

Example Input: [header] How to insulate a basement [title] These concrete blocks are usually installed at the time of construction or when the home is undergoing significant renovation. [step] Unless you possess expert masonry skills, leave this kind of basement insulation to a cement mason. [title] Purchase concrete blocks infused with foam insulation. <sep> (A) [step] The two common forms sold are autoclaved aerated concrete (aac) and autoclaved cellular concrete (acc). [title] Most commonly, foam board is installed between an exterior finish such as siding and the exterior wall's studs. (B) [step] Their characteristics could vary widely by brand (having inside houses and apartments) or, of course, by your personal experiences with the wall. [title] Get concrete for the area where the inside houses it, and variously label the concrete blocks. (C) [step] In a conventional house, the available concrete costs 120 by 300 square feet. In a program like yours, the amount of available concrete is drastically reduced. (D) [step] These can be either pre-oiled concrete or heavy bricks. These materials can be purchased at masonry supply stores or at home improvement stores.
