Passage: Dell sells personal computers (PCs), servers, data storage devices, network switches, software, computer peripherals, HDTVs, cameras, printers, MP3 players, and electronics built by other manufacturers. The company is well known for its innovations in supply chain management and electronic commerce, particularly its direct-sales model and its "build-to-order" or "configure to order" approach to manufacturing—delivering individual PCs configured to customer specifications. Dell was a pure hardware vendor for much of its existence, but with the acquisition in 2009 of Perot Systems, Dell entered the market for IT services. The company has since made additional acquisitions in storage and networking systems, with the aim of expanding their portfolio from offering computers only to delivering complete solutions for enterprise customers. Question: What market did Dell begin to compete in in 2009?
answer:
IT services

Passage: Historically, major professional orchestras have been mostly or entirely composed of male musicians. Some of the earliest cases of women being hired in professional orchestras was in the position of harpist. The Vienna Philharmonic, for example, did not accept women to permanent membership until 1997, far later than the other orchestras ranked among the world's top five by Gramophone in 2008. The last major orchestra to appoint a woman to a permanent position was the Berlin Philharmonic. As late as February 1996, the Vienna Philharmonic's principal flute, Dieter Flury, told Westdeutscher Rundfunk that accepting women would be "gambling with the emotional unity (emotionelle Geschlossenheit) that this organism currently has". In April 1996, the orchestra's press secretary wrote that "compensating for the expected leaves of absence" of maternity leave would be a problem. Question: Which major orchestra was the last to appoint a woman to a permanent position?
answer:
the Berlin Philharmonic


question:
Passage: The appearance of more systematic, abstract thinking is another notable aspect of cognitive development during adolescence. For example, adolescents find it easier than children to comprehend the sorts of higher-order abstract logic inherent in puns, proverbs, metaphors, and analogies. Their increased facility permits them to appreciate the ways in which language can be used to convey multiple messages, such as satire, metaphor, and sarcasm. (Children younger than age nine often cannot comprehend sarcasm at all.) This also permits the application of advanced reasoning and logical processes to social and ideological matters such as interpersonal relationships, politics, philosophy, religion, morality, friendship, faith, democracy, fairness, and honesty. Question: The appearance of more systematic, abstract thinking is a notable aspect of what type of development during adolescence?
answer:

cognitive
