This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

[Q]: Passage: In 1982, Regis McKenna was brought in to shape the marketing and launch of the Macintosh. Later the Regis McKenna team grew to include Jane Anderson, Katie Cadigan and Andy Cunningham, who eventually led the Apple account for the agency. Cunningham and Anderson were the primary authors of the Macintosh launch plan. The launch of the Macintosh pioneered many different tactics that are used today in launching technology products, including the "multiple exclusive," event marketing (credited to John Sculley, who brought the concept over from Pepsi), creating a mystique around a product and giving an inside look into a product's creation.
[A]: Who was brought in to shape the marketing of Macintosh in 1928?


[Q]: Passage: From the 19th century, there was a revival in many ancient glass-making techniques including cameo glass, achieved for the first time since the Roman Empire and initially mostly used for pieces in a neo-classical style. The Art Nouveau movement made great use of glass, with René Lalique, Émile Gallé, and Daum of Nancy producing colored vases and similar pieces, often in cameo glass, and also using luster techniques. Louis Comfort Tiffany in America specialized in stained glass, both secular and religious, and his famous lamps. The early 20th-century saw the large-scale factory production of glass art by firms such as Waterford and Lalique. From about 1960 onwards there have been an increasing number of small studios hand-producing glass artworks, and glass artists began to class themselves as in effect sculptors working in glass, and their works as part fine arts.
[A]: What famous lampmaker used factory production?


[Q]: Passage: 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.
[A]:
What market made up the minority of Dell's sales?
