question:
[header] How to ask survey questions [title] Understand your objective. [step] Make sure you know why you are asking questions in the survey. Having a firm grasp of this will help you make better questions. <sep> (A) Without knowing your objective, your questions may seem aimless. [substeps] Try to answer the questions: who, what, where, when and why for yourself. (B) [substeps] However, you may not have a completely clear and accurate understanding of your evaluation topic. You may need the fact-figure accuracy to have a clear and reliable assessment. (C) You can additionally foster a good relationship between you and the question that came up.

question:
[header] How to elevate your hand while sleeping [title] Sleep on your back or side. [step] In order to elevate your hand while you're sleeping, you'll need to sleep on your back or on the side opposite of the arm that needs elevation. This is the easiest resting position for elevating your hand. <sep> (A) [substeps] Lying on your side not only has been shown to help alleviate hand inflation, but it also improves circulation in and around the hand and wrist joints. It's also more efficient than sleeping on your side. (B) [substeps] You can use a pillow to support your arm when you start to feel like your hand's elevating off the ground. Place a rolled up towel over your head to help prevent air from pooling near your arm. (C) [substeps] Sleeping on your stomach won't allow you to elevate your hand as easily. It's much harder to prop it up from behind if you're lying flat on your stomach. (D) [substeps] Lie on your back with the pillow propping your head up at a 45 degree angle. Your dominant hand should support the bottom of your pillow.
answer:
C


question:
[header] How to be comfortable wearing high heels when you're tall [title] Find the right heel height. [step] If you don't have much experience with wearing high heels, choose a lower heel to start. Start small, with a one inch heel, and continue increasing height as you become more comfortable walking. <sep> (A) Once you've mastered the one inch heel, try a one and a half inch heel, and keep increasing your heel height by half of an inch. [substeps] If you want to try different kinds of heels without breaking the bank, try purchasing different types of shoes with heels that can be worn with different outfits. (B) [substeps] Once you master the basics of high heels, you can move up to having them measured to your height. Once you're comfortable with the basics, you can work on having them measured more frequently. (C) [substeps] If you're feeling less confident about your height, consider different styles of heels. A slight heel is fine as long as it's the correct height. (D) For example, you might try a hi heel shoe while standing on the balls of your feet. [substeps] When you pick a high heel, look at how it sits on your ankles while you're walking, as you might find it too high.
