[Q]: [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.
[A]: C


[Q]: [header] How to use dance movement therapy [title] Find a certified dance therapist. [step] Search for a therapist who is qualified to provide dance and movement therapy. The person should be a registered dance therapist. <sep> (A) Three-dimensional and dynamic dance therapy will be hard for a dance therapist to follow. Asking for a referral can take several months and is expensive. (B) If you are not employed or licensed, you may qualify for regular sessions with her or him. If you work at a dance studio, you might want to consider a person with a dance degree through the national dance accreditation council (a&r) or the accreditation (tacp) commission on dance activity therapy. (C) This means they've completed extensive training in clinical work using dance therapy and can provide high quality care. [substeps] You may find a dance therapist through a program at a local hospital or at a therapy clinic. (D) There are other career paths than dance therapy, like dance or music therapy, but these do require evaluation by an independent therapist. Evaluate the methods the dance therapist uses to improve your technique and control your dance moves.
[A]: C


[Q]: [header] How to decorate your door for winter [title] Hang a traditional christmas wreath. [step] Wreaths are a winter-and christmas-decoration staple, and will look good on almost any front door. Tie a red ribbon or bow around your wreath to create an appealing visual contrast. <sep> (A) [substeps] You can get the hardiest ribbons you can find from your local hardware store, or just hang your wreath on the doorknob or trim. A festive wreath in a style that matches your christmas décor is a nice touch. (B) You can purchase winter wreaths at any craft store, and during the holidays, local hardware stores should stock wreaths as well. [substeps] The wreath should come with materials to hang it over your door, such as an over-the-door clip. (C) [title] Paint your entire door a festive color. [step] Use a stain remover and a salt spray paint pen to apply the color in a geometric pattern across your whole door. (D) Hang a bright christmas banner over your front door so that it stands out. Don't overdo the red; big lettering is good.
