PROBLEM: [header] How to play sepak takraw [title] Set up the court. [step] The court is rectangular and measures 13. 4 meters by 6.1 meters, approximately the same size as a badminton court. The net is in the middle of the court and should be 1.52 m high. <sep> (A) [substeps] The court runs on one side of the lower part of the court. It is normally used between three or four rows, to remove knee-guards and to protect the entire court from any further slugs (skeletons or other animals). (B) On the inside of the court, you'll see rows and rows and elevated 18 x 19 meters by testing a platform. If you don't expect to play every day, you'll still be able to play as much as you want. (C) A service circle should be drawn 3.05 m from the back line and 2.45 m from the sidelines. The radius of the service circle should be 0.3 m. (D) You should place your face-plates face down on each side of the court, like you are a goldfish. You can also drop your finger or both of your hands on the court's edge and play.

PROBLEM: [header] How to make football brownies [title] Preheat the oven and melt the butter with the unsweetened chocolate. [step] Turn the oven on to 350 degrees f (176 c). Get out a medium saucepan and place 1 cup (226 g) of butter in it. <sep> (A) Turn the heat to medium low and let the butter melt for about 1 minute or until it melts. [substeps] It's best to use unsweetened butter because it doesn't contain the white chocolate protein it caramelizes more effectively. (B) Stir the two together with a wooden spoon until melted and the mixture is smooth. [substeps] You can use either unsweetened or unsweetened chocolate. (C) Place a sieve over the top to break up any remaining clumps of butter and sugar that might be settling in the butter and place the bowl inside the pan. [substeps] If you prefer, you can use a stand mixer that is set to low speed or you can run a light mixer over the top. (D) Chop 6 ounces (170 g) of unsweetened chocolate into chunks and add it to the saucepan. Melt the butter with the chocolate over low heat.

SOLUTION: D

PROBLEM: [header] How to wash a blanket [title] Fill a tub with cool water and add detergent. [step] Find a tub or basin large enough for your blanket to fit in and fill it up with cool water. Mix in mild detergent and let it spread through the water. <sep> (A) You can use a washcloth or a soft toothbrush to scrub the blanket and prevent it from sticking to the water. This should prevent dirt from accumulating on the blanket as you wash it. (B) You'll essentially be doing the same thing as a washing machine on a gentle setting, only manually, which gives you greater control over how the blanket is treated and helps ensure that every part gets clean. [substeps] Don't fill the tub up too much or it may overflow when you put the blanket in. (C) [substeps] If the water feels too hot, fill a small bucket with cool water and add your blanket. You can also place the blanket in the sink and let it soak for a minute or two to warm up the water, so that it can absorb the detergent. (D) Allow it to sit for 5 minutes, then wipe it with a clean, soft, lint-free towel. [substeps] Ensure to keep the water to at least 60 percent of the required temperature as you wash your blanket.
