[Q]: proper question: Tymnet worked with what?
disfluent question: What did Tymnet connect no no what did Tymnet work with rather?
context: Tymnet was an international data communications network headquartered in San Jose, CA that utilized virtual call packet switched technology and used X.25, SNA/SDLC, BSC and ASCII interfaces to connect host computers (servers)at thousands of large companies, educational institutions, and government agencies. Users typically connected via dial-up connections or dedicated async connections. The business consisted of a large public network that supported dial-up users and a private network business that allowed government agencies and large companies (mostly banks and airlines) to build their own dedicated networks. The private networks were often connected via gateways to the public network to reach locations not on the private network. Tymnet was also connected to dozens of other public networks in the U.S. and internationally via X.25/X.75 gateways. (Interesting note: Tymnet was not named after Mr. Tyme. Another employee suggested the name.)

[Q]: proper question: When was Phags-pa script destroyed?
disfluent question: When was the Phags-pa script invented no I guess when was it destroyed?
context: Since its invention in 1269, the 'Phags-pa script, a unified script for spelling Mongolian, Tibetan, and Chinese languages, was preserved in the court until the end of the dynasty. Most of the Emperors could not master written Chinese, but they could generally converse well in the language. The Mongol custom of long standing quda/marriage alliance with Mongol clans, the Onggirat, and the Ikeres, kept the imperial blood purely Mongol until the reign of Tugh Temur, whose mother was a Tangut concubine. The Mongol Emperors had built large palaces and pavilions, but some still continued to live as nomads at times. Nevertheless, a few other Yuan emperors actively sponsored cultural activities; an example is Tugh Temur (Emperor Wenzong), who wrote poetry, painted, read Chinese classical texts, and ordered the compilation of books.

[Q]: proper question: What doesn't introduce inequality to a country?
disfluent question: Who or no make that what doesn't introduce inequality to a country?
context: Economist Simon Kuznets argued that levels of economic inequality are in large part the result of stages of development. According to Kuznets, countries with low levels of development have relatively equal distributions of wealth. As a country develops, it acquires more capital, which leads to the owners of this capital having more wealth and income and introducing inequality. Eventually, through various possible redistribution mechanisms such as social welfare programs, more developed countries move back to lower levels of inequality.
