Input: Consider Input: [header] How to wear rings [title] Use a ring-sizer to find the appropriate size for a ring. [step] Ring-sizers are plastic sheets with a variety of different sizes on them, which you can slide your finger into to find an appropriate fit. These are available at every jewelry counter for sizing rings. <sep> (A) [substeps] Your ring should fit your finger comfortably. It needs to be snug enough so that it stays on, but loose enough to slide off at the knuckle. (B) Use your ring-sizer to find a size that fits your finger size-which sounds easy. [substeps] A ring size 14-inch (27.6 cm) is approximately the ideal size, though it can add a mature look to a ring. (C) Many rings, especially those with 3 or more sizes, will fit comfortably onto your ring. [substeps] You can also do this freehand by simply finding a ring-sizer with a similar size. (D) When one is worn, do not buy one with rounded sides. This is likely to break or splinter, and it will probably have uva, bva, and uvb features of the ring.

Output: A

Input: Consider Input: [header] How to calculate man hours [title] Divide your project into components. [step] The first part of calculating the man-hours you will need to do a job is to split up the project into smaller components. Then estimate the amount of hours needed to complete each component. <sep> (A) This formula allows you to divide the time needed to come up with the total number of hours needed for your project. [substeps] Example: if you divide the amount of hours needed to complete the project by 11, then you would get 11 hours of man hours. (B) [substeps] Once you've determined the total number of hours you will need to complete the task you'll be doing, add those hours to that number. For example, if you will be working on a project that's 50 pages long, subtract 50 for 80 minutes. (C) These components should be designated according to the type of labor involved. If you are building an apartment complex, you will need excavation, construction, electrical, plumbing, and so on. (D) Once all components have been completed, calculate the man hours you will need to do, after which time you will divide the total amount of time that you should take to complete each component. [substeps] Schedule an appointment if you need to discuss the work in detail.
