Example Input: [header] How to carry a hedgehog [title] Don't be nervous. [step] Hedgehogs are great at sensing fear, and if you are scared and nervous, they will be scared and nervous, making it a bad experience for everyone. [title] If you are going to handle a hedgehog, pick it up. <sep> (A) [step] Grasp its tail firmly with two hands placed on either side of its spine and hoist it up on a sturdy, sturdy surface. [title] Hold your hedgehog's whiskers on the inside of your hand. (B) [step] This is a relatively simple thing to handle-a hedgehog can bite you if you touch it. Instead, just hold it close to your body, and let go, be aware of how many times you are holding your pet. (C) [step] Place your hand on the animal's shoulder, gently turn its head towards you, and release a calming word. Walk slowly around the hedgehog, holding the animal securely and gently holding the neck and head. (D) [step] Don't mess around and try to poke it awake or make it aware of your presence by hovering your hand. Hedgehogs are prey animals with poor eyesight, and this is seen as a threatening gesture.
Example Output: D

Example Input: [header] How to buy a last minute cheap flight [title] Check airline newsletters, websites that specialize in last minute air travel and the travel section of your local newspaper to find last minute deals on flights. [step] Sometimes you can save money by booking flights late because airlines that have not filled their planes will offer discount fares. [title] Compare airfares from different airlines, websites and travel agencies. <sep> (A) [step] Look at every airline's website so that you can compare and contrast prices. [title] Opt for free flights as before, otherwise follow the full booking program and you'll not miss your flight in a long time. (B) [step] Try booking flights from big-ticket airlines such as kiwi airlines and delta. [title] Compare prices from travel agencies that are offering cheaper flights. (C) [step] Purchasing flights directly from the airline is not always the cheapest deal, so check out a few different travel websites and travel agencies to compare prices. [title] Search for flights during undesirable days and times. (D) [step] Compare each airline's prices with the prices you are interested in. You might be able to find a cheaper flight for free.
Example Output: C

Example Input: [header] How to argue with parents successfully [title] Pick your battles. [step] You shouldn't argue with your parents every time you disagree with them, if only because this strategy will make it harder for you to win when the argument is about something that is really important to you. [substeps] Weigh the benefits versus the costs. <sep> (A) If the topic of the argument is significant to you, it might be worth the effort and the possible consequences of engaging in an argument with your parents. However, if there are minimal worthwhile results, it might be best to let this one go. (B) For example, you might argue that your parents don't have enough hours, for example, or your parent may not be able to take you to court every weekend because you don't like to do chores. Your parents may try to argue back however. (C) Arguing over something that you really don't care about is not appealing to your parents. They might, for example, raise medical bills or the difference between lunch money and gas money for you, because you argue over the need to use the bathroom while your parents cook dinner. (D) Arguing with your parents about something that is really important to you will probably not be as effective as it could be, and it won't make you feel better, especially if the argument will come with little or no concessions. Fighting may seem obvious, but dealing with your parents individually can be a huge difference.
