Input: Consider Input: [header] How to bend rebar [title] Understand the structural issues possible with manually-bent rebar and know how to avoid them. [step] When you bend metal, you naturally weaken it. When done correctly, however, you can minimize damage and still get the shape you need to complete the project. <sep> (A) [substeps] Badly bent rebar acts as a buffer for the metal particles of the laser beam. The piece of rebar you are bending dissolves when squeezed into contact. (B) This effect is part of the re-bend method. The process is a little different than rebending a rubber band, but the difference is that you bend it in half by simply opening up a v on each end. (C) Because of this, it's important for you to know how to modify the shape you want the rebar to be. If you have a badly bent rebar, you'll likely create grooves in the rebar that introduce excess material. (D) Keep the following in mind as you work : [substeps] Always note the grade and size of the bar you're bending, checking against the equipment you're using to ensure it works. Check with your project engineer to ensure your bends meet the minimal internal bend diameter.

Output: D


Input: Consider Input: [header] How to handle a kitten [title] Be gentle and patient when picking up the kitten. [step] Kittens are very small and fragile, so make sure you're using a very light touch and gentle care. If the kitten shows signs that it doesn't want to be touched, like avoiding your touch or running from your hand, leave it alone and try again at a later time. <sep> (A) [title] Handle your kitten slowly and with caution. [step] Depending on when you picked the kitten up, you may need to start with a short cuddle, and gradually move from there. (B) [substeps] Watch out for the mother cat, who may not want anyone handling her kittens. She may bite or scratch people to prevent them from touching the kittens. (C) Talk to a familiar person or pet when picking up the kitten if you think you can cut away some of its protective protective bubble. [title] Avoid picking up the kitten from its mother. (D) Just imagine that you were picking your kitten up by its neck, holding one hand over its head, and guiding its ears, not gently placing one hand on its head. That gives the kitten shock, so be careful of hurting the kitten.

Output: B


Input: Consider Input: [header] How to roast a pig [title] Set the temperature of your grill around 200 to 250ºf (93.3 to 121.1ºc). [step] Generally, grills will have a built in thermometer where you can monitor the temperature. However, if your grill doesn't have a thermometer, you insert a large meat thermometer into the top vent to check the temperature. <sep> (A) [substeps] If possible, place your grill in a shielded area where wind will not hit it directly. Wind and the outside temperature can have an effect on the internal temperature of the grill. (B) [substeps] Some grimesters will simply set to the 160ºf (38.4 ° c) setting. [title] Place one piece of meat at a time on the grill. (C) [substeps] American bbq grills do not need an outdoor thermometer. You can feel the difference just by breaking the grate at roughly 0.020 ° f (13 ° c). (D) [substeps] If using a meat thermometer, use a pair of long-handled tongs to put the thermometer next to your griddle. [title] Add salt to the roasting tray.
