[Q]: [header] How to catch lake trout [title] Use a light-action rod with 4 to 6 pound test line. [step] This is the best rod to use for trout fishing and allows you to use a variety of techniques to catch your trout. The lighter line has less friction with the water, allowing you cast your line to the very bottom of the lake with ease. <sep> (A) All you have to do is lightly tap the rod with your finger to get some water onto the rod. [title] Get your hand used to the catch. (B) The slower you cast the rod, the more power your line will have. [substeps] Be aware that certain fishermen only use lighter lines when they plan on doing something else. (C) [substeps] Some lake trout can be over 35 pounds, you will need a heavier rod for these. If you know you're fishing a lake that has massive fish, bring a heavier rod as well. (D) [substeps] Watch out for small rocks in the water if you're unsure how to cast your line. The rocks reflect off of lake trout very easily.
[A]: C


[Q]: [header] How to stay beautiful [title] Adhere to a proper diet. [step] Most people think of dieting as cutting back on food, or at least eating less of the things you want. Fortunately, this is not the case. <sep> (A) Even though eating less is important, some people find that excessive calories will trigger body type issues like a body mass index, which is the fact that people aren't too quick to begin with a meal. [substeps] Inadequate sources of protein (such as meat or peas) are also linked to body image issues like muscle loss. (B) Instead, a proper and sustainable diet replaces empty calories (like processed cheeseburgers and soda) with healthy alternatives. Depending on what your diet currently consists of, you can probably think of at least a few things you eat that your body would technically be better off without. (C) You simply remember your body and the things you need to eat to stay healthy. Get enough calories and get into shape. (D) There is a tendency of people to end up missing out on calories because they're trying to stay healthy. In fact, it can be hard to keep up with it because you simply try to make yourself feel better.
[A]: B


[Q]: [header] How to put a cot together [title] Take an inventory. [step] The cot should have three separate pieces: a metal frame with canvas attached to it and two separate metal rails. [substeps] When you first get the cot, the primary metal frame will likely be folded up. <sep> (A) This frame, along with the canvas, will eventually be narrower. If this is the case, remove the frame and line up the hinges on the side of the frame with the two metal rails. (B) Different era frames may also get folded up quickly, such as cupboards fitted with shelves under the inner frame, or moving grates added to the outer frames to distribute the weight over time. Larger frames will also have double outer covers. (C) You should be able to see the canvas attached to the frame as it is folded, though. The two separate metal rails will be used for support, and they will slide into the ends of the attached canvas once the frame has been opened up. (D) Slide the metal frame over the top of the wooden frame, then slide it back on. Make sure that you space the gaps between the two frames so that you can see both sides.
