In one sentence, describe what the following article is about: Many synthetic wigs do not respond well to heat; some might melt when you're opening the lid of a hot oven or trying to blow-dry them. Before using any heated hair-styling tools on your wig, make sure to check its label. Look for phrases like “heat-friendly” or “heat-resistant.” If there is none, you shouldn't risk burning your wig. Even if your wig is heat-friendly, opt for the lowest heat in order to avoid damaging your wig. If you set the flat iron too high, the wig might melt. Wait a few minutes until the iron is hot enough. Ideally the temperature of the flat iron shouldn't exceed 240° F (116° C). When the wig is on the mannequin head, use your hands to divide it into two layers: top and bottom. Use to clip to stabilize the top layer. Take a small section from the bottom, around 1 inch (2.5 cm) in width, and apply the iron from the roots to the ends. Once you're done with the bottom layer, take off the clip, and take a small section from the top layer. Apply the flat iron, using the same method as you did on the bottom layer. Continue until you covered every part of the wig. Don't hold the flat iron on one spot for longer than a few seconds, as overexposure to heat might harm the wig. During straightening, gently brush out the wig using a natural bristle brush. This will help make the strands look soft and shiny. If you don't have a straightener or want a softer feel, go for a hot-air brush. You can use it after lightly spraying the wig with detangler, fabric softener, or plain water. Move it down the wig slowly, letting the brush dry the fibers.
Summary: Check if your wig can bear exposure to heat. Preheat your flat iron on the lowest temperature. Clip up the top layer of the wig, and straighten the bottom layer. Remove the clip, and iron the top layer. Use a natural bristle brush while heat-styling your wig. Use a hot-air brush on your wig for increased volume and softness. Finished.

The base of the loop should be right up against the eyelet the lace is coming out of. Make the loop about 1 inch (2.5 cm) long. If it’s any longer or shorter, you may not be able to tie the knot later on. Pinch the base of the loop between your index finger and thumb so it stays in place. Grab the end of the lace and bring it over and under the loop until it’s back where it started. Part of the lace should now be wrapped around the base of the loop, holding it in place. Each wrap around should be right up against the previous one. Stop wrapping the lace around the loop when you’re about .25 inches (0.64 cm) away from the end of the loop. When you stop, there should still be a tiny bit of the loop peeking out from the wrapped lace. Wrap the end of the lace over and under one side of the loop so that the end goes through the center of the loop. Once the end is through the center, pull it tight with your fingers. Once you pull it tight, the knot is finished on that side of the boot. Tie the same knot on the other side of your boot using the other end of the lace. To tighten the knot on your boot, scrunch the lace wrapped around the loop down toward the end of the lace until it's fully compacted. To loosen your boot, pull the wrapped lace up away from the end of the lace so that it's loosely wrapped around the lace coming out of the eyelet. To easily slip your boot on and off, loosen the knots on each side of the boot. Then, once the boot is on your foot, tighten the knots again.

One-sentence summary -- Create a small loop with the lace on the left side of your boot. Wrap the lace around the base of the loop. Keep wrapping the lace around the loop until you’re near the end of the loop. Push the end of the lace through the end of the loop. Adjust the knot by scrunching or loosening the wrapped lace.

Q: Chicago style treats regulations as though they don't have an author, so the first part of your reference entry is the title of the regulation. Type the title in title-case, surrounded by quotation marks. Put a period at the end of the title, inside the quotation marks. Spell out the Code of Federal Regulations in italics, followed by a comma. Type the word "title," followed by the title number. Type a space, then put the year of the code edition in parentheses. Place a colon after the closing parentheses mark. After the colon, provide the page numbers from the print edition of the CFR. Do not use any abbreviations before the numbers, such as "p." Place a period after the last page number digit.  If you accessed the CFR online, go to the Government Printing Office website at gpo.gov to get a PDF of the print version of the regulation. That way, you'll have a page number. If you accessed the CFR online, the last part of your reference entry will be the direct URL or "permalink" for the regulation. Use the PDF available from the GPO, so that you have an online copy of the official print edition of the code. Place a period at the end of the URL. When using a footnote for in-text citation, include all the same information you included in your reference list entry. However, instead of placing periods between the elements, use commas. The only period in a footnote is at the end.
A: Start your reference entry with the title of the regulation. List the CFR title number and year of publication. Identify the page numbers where the regulation appears. Provide a direct URL for the regulation. Use commas instead of periods in footnotes.

INPUT ARTICLE: Article: Biographies, autobiographies and articles can be read, analyzed and discussed by gifted students. Leaders will be able to identify and discuss the contributions science has made to the modern world. Leaders need to prepare and present ideas clearly and authoritatively, and students can learn that by writing and delivering speeches, conducting research and doing reports. Gifted students need to explore creativity and the trends and lives of artists who have been leaders in their fields. This is especially useful for gifted students at the secondary school level. Group participation and team activities will teach kids to encourage and motivate each other. For example, high school students might try college level courses over the summer or can tutor younger students.

SUMMARY:
Emphasize leadership training in all academic areas at school, including the arts. Include reading and discussion about great leaders. Use science classes to allow students to engage in critical thinking, analysis and creative problem solving. Utilize humanities classes to help gifted students express their leadership through oral and written communication. Include the fine and performing arts. Offer specific courses on leadership. Nurture leadership in gifted students with extracurricular activities. Enroll in summer classes, and keep gifted kids engaged in learning and activities when they are not in school.
