Input: Read this: IBM has constantly evolved since its inception. Over the past decade, it has steadily shifted its business mix by exiting commoditizing markets such as PCs, hard disk drives and DRAMs and focusing on higher-value, more profitable markets such as business intelligence, data analytics, business continuity, security, cloud computing, virtualization and green solutions, resulting in a higher quality revenue stream and higher profit margins. IBM's operating margin expanded from 16.8% in 2004 to 24.3% in 2013, and net profit margins expanded from 9.0% in 2004 to 16.5% in 2013.

This technique was very expensive, though, and could not be used for applications such as telemedicine, distance education, and business meetings. Attempts at using normal telephony networks to transmit slow-scan video, such as the first systems developed by AT&T Corporation, first researched in the 1950s, failed mostly due to the poor picture quality and the lack of efficient video compression techniques. The greater 1 MHz bandwidth and 6 Mbit/s bit rate of the Picturephone in the 1970s also did not achieve commercial success, mostly due to its high cost, but also due to a lack of network effect with only a few hundred Picturephones in the world, users had extremely few contacts they could actually call to, and interoperability with other videophone systems would not exist for decades.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Why did using business meetings to transmit slow-scan video fail?
Ah, so.. unanswerable

Question: Quite a few words from the variety of Old Chinese spoken in the state of Wu (where the ancestral language of Min and Wu dialect families originated and which was likely influenced by the Chinese spoken in the state of Chu which itself was not founded by Chinese speakers),[citation needed] and later words from Middle Chinese as well, have retained the original meanings in Hokkien, while many of their counterparts in Mandarin Chinese have either fallen out of daily use, have been substituted with other words (some of which are borrowed from other languages while others are new developments), or have developed newer meanings. The same may be said of Hokkien as well, since some lexical meaning evolved in step with Mandarin while others are wholly innovative developments.
Try to answer this question if possible: What changes have happened to Wu compared to Mandarin?
Answer: unanswerable

Input: Read this: Canada has the world's largest deposit of natural bitumen in the Athabasca oil sands and Canadian First Nations along the Athabasca River had long used it to waterproof their canoes. In 1719, a Cree Indian named Wa-Pa-Su brought a sample for trade to Henry Kelsey of the Hudson's Bay Company, who was the first recorded European to see it. However, it wasn't until 1787 that fur trader and explorer Alexander MacKenzie saw the Athabasca oil sands and said, "At about 24 miles from the fork (of the Athabasca and Clearwater Rivers) are some bituminous fountains into which a pole of 20 feet long may be inserted without the least resistance."
Question: Alexander MacKenzie was a oil trader and saw the oil sands in what year?

Output:
unanswerable
