Problem: The coastal plain transitions to the Piedmont region along the Atlantic Seaboard fall line, a line which marks the elevation at which waterfalls first appear on streams and rivers. The Piedmont region of central North Carolina is the state's most urbanized and densely populated section. It consists of gently rolling countryside frequently broken by hills or low mountain ridges. Small, isolated, and deeply eroded mountain ranges and peaks are located in the Piedmont, including the Sauratown Mountains, Pilot Mountain, the Uwharrie Mountains, Crowder's Mountain, King's Pinnacle, the Brushy Mountains, and the South Mountains. The Piedmont ranges from about 300 to 400 feet (91 to 122 m) in elevation in the east to over 1,000 feet (300 m) in the west. Because of the rapid population growth in the Piedmont, a significant part of the rural area in this region is being transformed into suburbs with shopping centers, housing, and corporate offices. Agriculture is steadily declining in importance. The major rivers of the Piedmont, such as the Yadkin and Catawba, tend to be fast-flowing, shallow, and narrow.
At what point does the coastal plin transition to the Piedmont region?
The answer is the following: along the Atlantic Seaboard fall line

Problem: The flower may consist only of these parts, as in willow, where each flower comprises only a few stamens or two carpels. Usually, other structures are present and serve to protect the sporophylls and to form an envelope attractive to pollinators. The individual members of these surrounding structures are known as sepals and petals (or tepals in flowers such as Magnolia where sepals and petals are not distinguishable from each other). The outer series (calyx of sepals) is usually green and leaf-like, and functions to protect the rest of the flower, especially the bud. The inner series (corolla of petals) is, in general, white or brightly colored, and is more delicate in structure. It functions to attract insect or bird pollinators. Attraction is effected by color, scent, and nectar, which may be secreted in some part of the flower. The characteristics that attract pollinators account for the popularity of flowers and flowering plants among humans.
What have some structures evolved to protect?
The answer is the following: the sporophylls

Problem: According to Italian fashion designer Roberto Cavalli, Beyoncé uses different fashion styles to work with her music while performing. Her mother co-wrote a book, published in 2002, titled Destiny's Style an account of how fashion had an impact on the trio's success. The B'Day Anthology Video Album showed many instances of fashion-oriented footage, depicting classic to contemporary wardrobe styles. In 2007, Beyoncé was featured on the cover of the Sports Illustrated Swimsuit Issue, becoming the second African American woman after Tyra Banks, and People magazine recognized Beyoncé as the best-dressed celebrity.
Which African-American woman before Beyonce had posed for SI Swimsuit issue?
The answer is the following: Tyra Banks

Problem: Early reviews were mixed in their assessment. Ken Tucker of Entertainment Weekly considered that "As TV, American Idol is crazily entertaining; as music, it's dust-mote inconsequential". Others, however, thought that "the most striking aspect of the series was the genuine talent it revealed". It was also described as a "sadistic musical bake-off", and "a romp in humiliation". Other aspects of the show have attracted criticisms. The product placement in the show in particular was noted, and some critics were harsh about what they perceived as its blatant commercial calculations – Karla Peterson of The San Diego Union-Tribune charged that American Idol is "a conniving multimedia monster" that has "absorbed the sin of our debauched culture and spit them out in a lump of reconstituted evil". The decision to send the season one winner to sing the national anthem at the Lincoln Memorial on the first anniversary of the September 11 attacks in 2002 was also poorly received by many. Lisa de Moraes of The Washington Post noted sarcastically that "The terrorists have won" and, with a sideswipe at the show's commercialism and voting process, that the decision as to who "gets to turn this important site into just another cog in the 'Great American Idol Marketing Mandala' is in the hands of the millions of girls who have made American Idol a hit. Them and a handful of phone-redialer geeks who have been clocking up to 10,000 calls each week for their contestant of choice (but who, according to Fox, are in absolutely no way skewing the outcome)."
What publication does Ken Tucker work for? 
The answer is the following:
Entertainment Weekly
