Problem: The slowing sales growth has been attributed to the maturing PC market, which constituted 66% of Dell's sales, and analysts suggested that Dell needed to make inroads into non-PC businesses segments such as storage, services and servers. Dell's price advantage was tied to its ultra-lean manufacturing for desktop PCs, but this became less important as savings became harder to find inside the company's supply chain, and as competitors such as Hewlett-Packard and Acer made their PC manufacturing operations more efficient to match Dell, weakening Dell's traditional price differentiation. Throughout the entire PC industry, declines in prices along with commensurate increases in performance meant that Dell had fewer opportunities to upsell to their customers (a lucrative strategy of encouraging buyers to upgrade the processor or memory). As a result, the company was selling a greater proportion of inexpensive PCs than before, which eroded profit margins. The laptop segment had become the fastest-growing of the PC market, but Dell produced low-cost notebooks in China like other PC manufacturers which eliminated Dell's manufacturing cost advantages, plus Dell's reliance on Internet sales meant that it missed out on growing notebook sales in big box stores. CNET has suggested that Dell was getting trapped in the increasing commoditization of high volume low margin computers, which prevented it from offering more exciting devices that consumers demanded.
What market made up the majority of Dell's sales?
The answer is the following: PC

Problem: The Melbourne rail network has its origins in privately built lines from the 1850s gold rush era, and today the suburban network consists of 209 suburban stations on 16 lines which radiate from the City Loop, a partially underground metro section of the network beneath the Central Business District (Hoddle Grid). Flinders Street Station is Melbourne's busiest railway station, and was the world's busiest passenger station in 1926. It remains a prominent Melbourne landmark and meeting place. The city has rail connections with regional Victorian cities, as well as direct interstate rail services to Sydney and Adelaide and beyond which depart from Melbourne's other major rail terminus, Southern Cross Station in Spencer Street. In the 2013–2014 financial year, the Melbourne rail network recorded 232.0 million passenger trips, the highest in its history. Many rail lines, along with dedicated lines and rail yards are also used for freight. The Overland to Adelaide departs Southern Cross twice a week, while the XPT to Sydney departs twice a day.
Which rail station is Melbourne's busiest?
The answer is the following: Flinders Street Station

Problem: Proto-Slavic, the supposed ancestor language of all Slavic languages, is a descendant of common Proto-Indo-European, via a Balto-Slavic stage in which it developed numerous lexical and morphophonological isoglosses with the Baltic languages. In the framework of the Kurgan hypothesis, "the Indo-Europeans who remained after the migrations [from the steppe] became speakers of Balto-Slavic".
The Indo-Europeans who remained after the migrations became speakers of what?
The answer is the following: Balto-Slavic

Problem: Antennas are characterized by a number of performance measures which a user would be concerned with in selecting or designing an antenna for a particular application. Chief among these relate to the directional characteristics (as depicted in the antenna's radiation pattern) and the resulting gain. Even in omnidirectional (or weakly directional) antennas, the gain can often be increased by concentrating more of its power in the horizontal directions, sacrificing power radiated toward the sky and ground. The antenna's power gain (or simply "gain") also takes into account the antenna's efficiency, and is often the primary figure of merit.
What is often the most imprtant crediting factor of antennas?
The answer is the following:
efficiency
