QUES: In late 2006[update], Dell lost its lead in the PC-business to Hewlett-Packard. Both Gartner and IDC estimated that in the third quarter of 2006, HP shipped more units worldwide than Dell did. Dell's 3.6% growth paled in comparison to HP's 15% growth during the same period. The problem got worse in the fourth quarter, when Gartner estimated that Dell PC shipments declined 8.9% (versus HP's 23.9% growth). As a result, at the end of 2006 Dell's overall PC market-share stood at 13.9% (versus HP's 17.4%).

What year did Dell gain its tech lead to Hewlett-Packard?

QUES: The "Lophotrochozoa" hypothesis is also supported by the fact that many phyla within this group, including annelids, molluscs, nemerteans and flatworms, follow a similar pattern in the fertilized egg's development. When their cells divide after the 4-cell stage, descendants of these 4 cells form a spiral pattern. In these phyla the "fates" of the embryo's cells, in other words the roles their descendants will play in the adult animal, are the same and can be predicted from a very early stage. Hence this development pattern is often described as "spiral determinate cleavage".
What animal contains no cells?

ANS: unanswerable


In 1841, Léon Escudier wrote of a recital given by Chopin that year, "One may say that Chopin is the creator of a school of piano and a school of composition. In truth, nothing equals the lightness, the sweetness with which the composer preludes on the piano; moreover nothing may be compared to his works full of originality, distinction and grace." Chopin refused to conform to a standard method of playing and believed that there was no set technique for playing well. His style was based extensively on his use of very independent finger technique. In his Projet de méthode he wrote: "Everything is a matter of knowing good fingering ... we need no less to use the rest of the hand, the wrist, the forearm and the upper arm." He further stated: "One needs only to study a certain position of the hand in relation to the keys to obtain with ease the most beautiful quality of sound, to know how to play short notes and long notes, and [to attain] unlimited dexterity." The consequences of this approach to technique in Chopin's music include the frequent use of the entire range of the keyboard, passages in double octaves and other chord groupings, swiftly repeated notes, the use of grace notes, and the use of contrasting rhythms (four against three, for example) between the hands.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who wrote about a Chopin 1841 recital?
Ah, so.. Léon Escudier


Question: The first use of asphalt/bitumen in the New World was by indigenous peoples. On the west coast, as early as the 13th century, the Tongva, Luiseño and Chumash peoples collected the naturally occurring asphalt/bitumen that seeped to the surface above underlying petroleum deposits. All three used the substance as an adhesive. It is found on many different artifacts of tools and ceremonial items. For example, it was used on rattles to adhere gourds or turtle shells to rattle handles. It was also used in decorations. Small round shell beads were often set in asphaltum to provide decorations. It was used as a sealant on baskets to make them watertight for carrying water. Asphaltum was used also to seal the planks on ocean-going canoes.
Try to answer this question if possible: What was used on turtle shells to provide decorations?
Answer: unanswerable
