The release of Apple's iPad tablet computer had a negative impact on Dell and other major PC vendors, as consumers switched away from desktop and laptop PCs. Dell's own mobility division has not managed success with developing smartphones or tablets, whether running Windows or Google Android. The Dell Streak was a failure commercially and critically due to its outdated OS, numerous bugs, and low resolution screen. InfoWorld suggested that Dell and other OEMs saw tablets as a short-term, low-investment opportunity running Google Android, an approach that neglected user interface and failed to gain long term market traction with consumers. Dell has responded by pushing higher-end PCs, such as the XPS line of notebooks, which do not compete with the Apple iPad and Kindle Fire tablets. The growing popularity of smartphones and tablet computers instead of PCs drove Dell's consumer segment to an operating loss in Q3 2012. In December 2012, Dell suffered its first decline in holiday sales in five years, despite the introduction of Windows 8.
Which division of Dell were unsuccessful in developing mobile devices?
****
The answer: mobility

Though Han wooden structures decayed, some Han-dynasty ruins made of brick, stone, and rammed earth remain intact. This includes stone pillar-gates, brick tomb chambers, rammed-earth city walls, rammed-earth and brick beacon towers, rammed-earth sections of the Great Wall, rammed-earth platforms where elevated halls once stood, and two rammed-earth castles in Gansu. The ruins of rammed-earth walls that once surrounded the capitals Chang'an and Luoyang still stand, along with their drainage systems of brick arches, ditches, and ceramic water pipes. Monumental stone pillar-gates, twenty-nine of which survive from the Han period, formed entrances of walled enclosures at shrine and tomb sites. These pillars feature artistic imitations of wooden and ceramic building components such as roof tiles, eaves, and balustrades.
How many stone pillar-gates survive from the Han era?
****
The answer: twenty-nine

Inheritance in plants follows the same fundamental principles of genetics as in other multicellular organisms. Gregor Mendel discovered the genetic laws of inheritance by studying inherited traits such as shape in Pisum sativum (peas). What Mendel learned from studying plants has had far reaching benefits outside of botany. Similarly, "jumping genes" were discovered by Barbara McClintock while she was studying maize. Nevertheless, there are some distinctive genetic differences between plants and other organisms.
Are plants and animals genetically the same?
****
The answer:
distinctive genetic differences
