Input: Consider Input: [header] How to take care of butterflies [title] Start with baby caterpillars. [step] If this is your first time raising caterpillars, you might want to start with a caterpillar kit. You can order a kit online and choose from a variety of butterfly species. <sep> (A) You can store all your butterflies at once in the kit. Just make sure not to overpack them in 1 location. (B) [substeps] Choose a caterpillar you'll be able to collect for some extra protection. You don't want a caterpillar whose wings are incredibly weak. (C) Make sure that the caterpillar is about 3 feet (0.6 m) in length. [substeps] If it is not small enough, you will have to wait several hours before you begin the process. (D) The kit will come with everything you need to raise the caterpillars into butterflies. If you prefer, you can instead find caterpillars in your neighborhood and provide what they need to become healthy butterflies.

Output: D

Input: Consider Input: [header] How to make a great first vlog [title] Make sure that you have the right equipment. [step] You don't need an expensive dslr camera and microphone, but you should have a camera that can handle video in 720p at the very least. You should also have an external microphone that hooks up to the camera. <sep> (A) Your vlog will only work if you have a mp3 player. [title] Get good quality editing software for your camera. (B) [substeps] For digital vlogs, you will need one with both video and audio capabilities, such as a vlog. [title] Change the camera speed when you make it first vlog. (C) [substeps] If you have a smartphone (or even a tablet), you don't need to buy any equipment to complement it. Sound is just as important as video, so don't neglect your microphone if you buy a dedicated one. (D) [title] Set up your vlog in a well-lit area. [step] If you plan to be shooting at night, you might as well go indoors, or it might be too stuffy and possibly might be too warm.

Output: C

Input: Consider Input: [header] How to take and print photos that look like photo booth pictures [title] Get your device and open the camera app. [step] Set it to the front-facing camera (the webcam). [substeps] If you have a regular camera and a tripod, then use the regular camera. <sep> (A) You only need to press and hold the shutter button for at least 30 seconds (or click and release the button) to take a picture. If not, get the assistant to either bring up pictures for you or point them out to you. (B) [title] Use the screen to control where you are zooming. [step] Zoom to one part of the screen at a time. (C) Put it on the tripod and set it so it takes the photo after 5 seconds. The photos will be more stable and you'll have extra time to get ready. (D) With a tripod, the photo booth camera (which can be set to whatever style you prefer) has two slots, one just for backing up parts. Though you can use flash to greatly increase the zoom capabilities, you won't be able to zoom at optimum magnification.
