Example: [header] How to create a christmas tree forest [title] Consider the type of tree you want to plant. [step] There are a wide variety of christmas trees and include fir, pine, spruce, cypress, and cedar. These trees thrive in different climates and look different from one another. <sep> (A) It is important to research the tree before setting up your tree to try it out to make sure you can write the tree's growing season so that you can get the most supplies you need. If you're just interested in having a tree stand out, then make sure to check for the following : [substeps] Spruce trees. (B) [substeps] Trees green may be used in a mix of green and evergreen. Greens, such as pintos and olive oil, may be more delicate than these. (C) Where the trees grow together is up to you. [substeps] Spruce trees light up the night for hours in the morning and drown out the morning sunrise between afternoons. (D) Think about where your tree forest will be located and choose a tree that can thrive in that climate. [substeps] Balsam firs are a popular christmas tree species that grow in the northern united states and canada, in hardiness zones 3-5 or states like minnesota, north dakota, and montana.
Output: D

New input case for you: [header] How to calculate how many calories you need to eat to lose weight [title] Calculate your basal metabolic rate (bmr). [step] Your bmr will tell you how many calories your body needs to function properly if you spent the entire day doing absolutely nothing. This is also known as your metabolic rate or metabolism. <sep> (A) You can calculate what percentage you lose on a regular basis using " bmr, " the body weight in pounds. [substeps] Bmr refers to the number of times a part of your body does some exercise and metabolism. (B) [substeps] Your body burns calories just to fulfill life-sustaining processes like breathing, digesting food, repairing and growing tissue and circulating blood. You will use the results from the bmr equation to find out how many calories you need to either lose weight or maintain your weight. (C) Bmr will come in a variety of forms. [substeps] Men should weigh between 200 and 875 bpa, while women should weigh between 450 and 675 bpa. (D) [substeps] The bmr can also be written down on a notepad or a spreadsheet, and it can be worked out by taking this little step and then dividing it by 5. As we said we need to eat between 10 , 000 and 1.25.
Output:
B
