Input: Consider Input: [header] How to train chickens to return to their coop [title] Prepare your chicken coop. [step] Before you can train your chickens to return to the coop in the evening, you need to ensure the coop is set up properly for your chickens. A basic chicken coop should provide at least twenty-four square feet of space and multiple places for chickens to perch. <sep> (A) To ensure proper lighting, you will need to buy a coop lamp or turn off the overhead light. You will also need to provide adequate heat. (B) Your chickens will probably also need a hutch, cart, or larder to keep them warm. All three features are important as you start building your chicken coop. (C) [substeps] Coop space should be compatible with how large or small your chickens may be. Don't space your chickens too close to each other. (D) [substeps] Make sure there is a plentiful supply of food and water inside the chicken coop. Wood beams mounted horizontally can provide good perching space for chickens.

Output: D


Input: Consider Input: [header] How to operate a manual pallet jack [title] Find the release lever. [step] Stand behind the manual pallet jack as this is the position you will be in when you move it. Find the small lever that allows the pallet jack prongs (the large flat metal pieces near the floor) to drop all the way down toward the floor. <sep> (A) Pass that lever over the top of the pallet jack, locking it in place with your fingertips. Keep the pallet jack in this position for 45 seconds, until it begins to tilt upwards slightly. (B) Lock the release lever in place and open the pallet jack by rotating it counter clockwise. [substeps] One second later, reverse the motion in the locked position and use the bucket with the release lever to hoist the pallet jack farther up. (C) [substeps] The pallet jack drop lever is often a small lever in the middle of the rounded handle, on the vertical stem of the manual machine. It may be distinguished by a different color of plastic, or otherwise marked, or it may not be. (D) [title] Pull the lever counterclockwise. [step] Steadily pull this lever counterclockwise.

Output: C


Input: Consider Input: [header] How to heat an eyelash curler [title] Clean your curler using soap and water. [step] Rub makeup cleanser or soap for sensitive skin on the pad and metal area of the curler with a cotton pad or sponge. Make sure there is no leftover makeup on the pad or metal parts of the curler. <sep> (A) [substeps] You should also take off any liners or creams you use because they make your skin more sensitive to makeup. [title] Store makeup in a plastic container with a cool mist. (B) Rinse all of the soap and residue off with water. [substeps] If your curler has makeup residue on the pad before you curl the lashes, the residue can create clumps of mascara and leave you with a less-than-ideal curl. (C) [title] Take an eyelid curler and put petroleum jelly or vaseline on each eyelid. [step] Your eyelids should be open and clear about 1 centimeter (0.4 in) from the place where the highlighter is applied. (D) You do not want to transfer the makeup from the container to your skin. [substeps] If you think the makeup that is on your curler or rod may flake away from the base of the curler or rod, use a cotton pad or sponge to pick it up.
