Problem: The NES uses a custom-made Picture Processing Unit (PPU) developed by Ricoh. All variations of the PPU feature 2 kB of video RAM, 256 bytes of on-die "object attribute memory" (OAM) to store the positions, colors, and tile indices of up to 64 sprites on the screen, and 28 bytes of on-die palette RAM to allow selection of background and sprite colors. The console's 2 kB of onboard RAM may be used for tile maps and attributes on the NES board and 8 kB of tile pattern ROM or RAM may be included on a cartridge. The system has an available color palette of 48 colors and 6 grays. Up to 25 simultaneous colors may be used without writing new values mid-frame: a background color, four sets of three tile colors and four sets of three sprite colors. The NES palette is based on NTSC rather than RGB values. A total of 64 sprites may be displayed onscreen at a given time without reloading sprites mid-screen. The standard display resolution of the NES is 256 horizontal pixels by 240 vertical pixels.

Problem: At the very end of the 19th century, a new style, with a carved top and back construction inspired by violin family instruments began to supplant the European-style bowl-back instruments in the United States. This new style is credited to mandolins designed and built by Orville Gibson, a Kalamazoo, Michigan luthier who founded the "Gibson Mandolin-Guitar Manufacturing Co., Limited" in 1902. Gibson mandolins evolved into two basic styles: the Florentine or F-style, which has a decorative scroll near the neck, two points on the lower body and usually a scroll carved into the headstock; and the A-style, which is pear shaped, has no points and usually has a simpler headstock.
 What style did the old style of mandolins supplant?

Problem: The Great Garden is an important European baroque garden. The palace itself, however, was largely destroyed by Allied bombing but is currently under reconstruction.[citation needed] Some points of interest are the Grotto (the interior was designed by the French artist Niki de Saint-Phalle), the Gallery Building, the Orangerie and the two pavilions by Remy de la Fosse. The Great Garden consists of several parts. The most popular ones are the Great Ground and the Nouveau Jardin. At the centre of the Nouveau Jardin is Europe's highest garden fountain. The historic Garden Theatre inter alia hosted the musicals of the German rock musician Heinz Rudolf Kunze.[citation needed]
What are the two least popular areas of the garden?
