Input: Consider Input: [header] How to determine who has right of way [title] Come to a complete halt at a stop sign or red light. [step] At a stop sign, come to complete halt for about 2 seconds or until vehicles that arrived before you clear the intersection. If you're stopped at a red light, proceed when the light has turned green. <sep> (A) This will give you enough time to catch the light and clear the intersection. [substeps] Vehicles behind or behind you may not brake. (B) This blocks oncoming cars from passing you. [substeps] If in doubt, you can also tell if you're going too fast by looking ahead at the tires of that car. (C) If you are stopped before a red light signals for another vehicle, you're on your own. [substeps] This means every car crossed before you has passed, and every vehicle in the intersection has stopped before you. (D) If the intersection has a white stripe in your lane, stop before this line. [substeps] If you have a stop sign, but the street you're crossing does not have a stop sign, wait until all traffic has cleared before crossing the intersection.

Output: D


Input: Consider Input: [header] How to prevent greasy hair [title] Shampoo properly. [step] Apply a small, quarter-sized amount of shampoo to your scalp and massage vigorously with your fingertips. Then, work the lather through your hair and rinse. <sep> (A) [title] Rub a dime-sized amount of baby oil in your palm. [step] Squirt a dime-sized amount of all-purpose baby oil into your palm and then use the back of a spoon to massage the lather into your hair. (B) Body wash will also work well to loosen the oil from your hair and prevent it from slacking off. Comb your fingers through your hair to ensure that all areas of your hair are clean. (C) [substeps] Whether you have wet or dry hair, lather the lather gently and never hold it in place for more than one second. [title] Consider bed-wetting your hair as often as you can. (D) Rinse hair thoroughly so no shampoo is left behind. Washing your hair should take about five minutes.

Output: D


Input: Consider Input: [header] How to blow a bubble with bubblegum [title] Buy some bubblegum. [step] You can buy gum at pretty much every corner store. Chewing gums can be used to make bubbles, but they won't be as big, and they'll usually pop too easily. <sep> (A) To start off, select a pack of bubblegum like double bubble or bazooka. Generally, if there is a picture of a bubble on the package, it's a good choice. (B) Try buying some beach-friendly stuff, such as liquid gum or soft gum, for those little bubbles-it will roll. [substeps] You can also check online for gum specifically for bubbles, as the flavors are often very subtle. (C) Carrot straws won't come as easily. [title] Apply a clear jelly/wax mixture to your lips. (D) Always follow the packaging instructions carefully, and don't use gum that contains tea and processed sugar. [title] Gather your supplies and make some bubbles.
