Q: The southern shagbark grows in limestone soils. Its leaflets are jagged-edged and come to sharp points, and grow 5 to a rachis. Shagbark twigs are thick and brown, and the bark is scaly and raised at the edges, giving it a shaggy appearance. The fruit of the shagbark, which grows to between 1.2 inches (3 cm) and 2 inches (5 cm) long, is oval and round, and is covered in a thick, dark husk. The shagbark nut meat is sweet. This species grows in moist forest, also called steam banks. The leaflets, which grow 9 to a rachis, are broad and smooth around the edges. The bitternut hickory fruit grows to be between 0.8 inch (2 cm) and 1.6 inches (4 cm) long, and is enclosed in a thin, dark brown husk. The kernel is bitter, as the plant's name suggests. Bitternut twigs are slender and green, and have distinctive yellow buds. The bark of a bitternut is light grayish-brown, and does not split deeply enough to flake. Pignut hickory trees grow on broad ridges. Their leaves consist of 5 sharply pointed, serrated edged, dark green and shiny leaflets on a short rachis. The thin pignut husk is light brown, and the round fruit, which grows to be about 1 inch (2.5 cm) long by 0.8 inch (2 cm) wide, is a similar light brown. Twigs are slender and a dark purple to a light green. The bark of a pignut is deeply recessed and scaly, but does not flake at the plate edges. The shellbark grows in wet, bottomland forests. Its leaflets are waxy and medium green, and come at least 9 to a rachis. At between 1.8 inches (4.5 cm) and 2.6 inches (6.5 cm) long and 1.5 inches (3.8 cm) wide, the fruit of the kingnut is the largest of the hickory species, and is enclosed by a thick, dark brown husk. The kingnut produces a sweet kernel. The twigs are thick, with round bulbs. The bark of the kingnut forms long, narrow vertical scales, which peel off from the top and bottom. The red hickory grows on slopes and forest ridges. Its leaflets are green and red, slender and tapered, and grow 5 or more to a rachis. The edges of the red hickory leaflets are smoothly serrated, as opposed to the sharp teeth of the pignut and southern shagbark. Red hickory nuts are 1 inch (2.5 cm) to 1.2 inches (3 cm) long and 0.8 inch (2 cm) wide, round, light brown and thin-shelled, and have a sweet taste. The husks are thin and dark brown. Red hickory bark is rough and deeply ridged into narrow vertical strips, but the bark does not scale or flake. Shagbark hickory trees grow in various environments, although they thrive in drained areas. The leaflets are light green, short and rounded, with pointed tips, and grow 5 or 7 to a rachis. The nuts of a shagbark hickory are 1.2 inches (3 cm) to 2 inches (5 cm) long, light brown, thin-shelled and sweet tasting, and are enclosed in a thick, brownish-black husk. As the name suggests, the shagbark tree is characterized by thick, scaly bark, giving the trunk a shaggy appearance. The sand hickory has matte, light green, narrow, pointed and smooth-edged leaflets. The nuts are the smallest of the hickory species, averaging only 0.5 inch (13 mm) to 1.45 inches (37 mm) long, with thin husks and shells and lightly colored nut meat. They are also round and covered with fine hairs. The nut meat of a sand hickory is sweet. Sand hickory bark is relatively smooth, and forms a compacted network of shallow furrows. Mockernut hickory trees grow in dry land, on slopes and ridges. The leaflets are waxy, medium green, wide and rounded, and grow 7 or more to a rachis. The edges of mockernut leaflets are softly serrated, with dull-edged teeth. The fruit of the mockernut is relatively small, at only 1.5 inches (3.8 cm) to 2 inches (5 cm) long, and contained by a thick, dark brown husk. Mockernut bark is characterized by deep, vertical furrows that are close together. The bark may also begin to furl at the edges and flake away as the mockernut reaches full maturity

Q: The original Flappy Bird game has unfortunately been revoked by its creator after he received a large amount of harassment about the game. While it is no longer available for new players, you can download any one of a number of clones. This can be done through the app store, Android market or Google play.  Some notable clones include: Silly Bird, Flappy Fish, Flappy Hipster, Fly bird, Tappy Nyan, and Flappy Bert (from Sesame Street)! You can also download the original game, but you will have to find it on the internet and install it manually. Just be sure to use a reputable website! The creator has recently stated that he will someday bring the game back to official channels, but that that will not happen any time soon. This game will require immense concentration if you wish to achieve a high score. This can entail the removal of pets from the room, lowering of music volumes or not sitting on an aisle seat whilst playing on a bus, for example. However, everybody has their own methods to increase levels of focus. Try experimenting with various external factors to find what suits you best.
