"In 1993 Iran became the second country in the Middle East to be connected to the Internet, and since then the government has made significant efforts to improve the nation's ICT infrastructure. Iran's national Internet connectivity infrastructure is based on two major networks: the public switched telephone network (PSTN) and the public data network. The PSTN provides a connection for end-users to Internet service providers (ISPs) over mostly digital lines and supports modem-based connections. The Data Communication Company of Iran (DCI), a subsidiary of TCI, operates the public data network." [Internet in Iran. Wikipedia]

"The Inland Customs Line which incorporated the Great Hedge of India (or Indian Salt Hedge[1]) was a customs barrier built by the British across India primarily to collect the salt tax. The customs line was begun while India was under the control of the East India Company but continued into the period of direct British rule. The line had its beginnings in a series of customs houses that were established in Bengal in 1803 to prevent the smuggling of salt to avoid the tax. These customs houses were eventually formed into a continuous barrier that was brought under the control of the Inland Customs Department in 1843." [Inland Customs Line. Wikipedia]

"The ACT (originally an abbreviation of American College Testing) college readiness assessment is a standardized test for high school achievement and college admissions in the United States produced by ACT, Inc. ...
The required portion of the ACT is divided into four multiple choice subject tests: English, mathematics, reading, and science reasoning. Subject test scores range from 1 to 36; all scores are integers. The English, mathematics, and reading tests also have subscores ranging from 1 to 18. (The subject score is not the sum of the subscores.) The composite score is the average of all four tests. In addition, students taking the optional writing test receive a writing score ranging from 1 to 36 (This is a change from the previous 2–12 score range). The writing score does not affect the composite score." [ACT (test). Wikipedia]
