Input: Consider Input: [header] How to exercise to prevent blood clots [title] Get up and move around. [step] Whether you're traveling by train, plane, or automobile, long-distance travel involves a lot of sitting. When you sit, you decrease circulation in your legs-especially if you sit with your legs crossed or with one foot under you. <sep> (A) If you are on a train or coach, the seat underneath you always feels flat, as if you are sitting. While there are good ways to stretch out your legs, there is not a lot a group of people can do. (B) This will help promote blood circulation to your feet. It will also keep you from rubbing your legs in an annoying manner-you can't promote blood flow when you're sitting on one leg. (C) [substeps] You can exercise while you drive or driving, although getting up and down on the exercise train can significantly improve circulation. You can also listen to music while you exercise, which will also help to prevent blood clots. (D) [substeps] If you're on a plane, try to get an aisle seat so you can get up and move around more easily. Ideally, you want to get up and stretch your legs or walk up and down the aisle once every hour or so.

Output: D


Input: Consider Input: [header] How to sail an optimist [title] Obtain all of the equipment needed (a rudder, dagger board, sail, mast, boom, and spirit pole etc). [step] These should all come with the boat. If you are buying the boat new, a decent seller will always include rigging equipment such as lines (ropes) and blocks (pulleys). <sep> (A) You will also need a hardy berth to ensure that no one gets hurt while on the boat. This includes outboards, rudder boards, boat trailers, ropes, etc. (B) Secure anything else that your boat will need and this is a great time to get things started. Be sure that you want to plan what you are going to do before starting. (C) Make sure these are the same material or specifications all of the boats on that particular ship will use. If in doubt about purchasing both ropes and anchors, only purchase the two. (D) These are extremely expensive for what they are and also difficult to assemble if you buy them separately. It is also recommended to buy a dolly with the boat as well.
