Answer: B. A writing system
Explanation: The Sumerians are the first known world civilization, which emerged on the land of Mesopotamia. In addition to the Sumerians, there were other Mesopotamian civilizations after, but one of the most important inventions or achievements that had an impact on the development of later civilizations was the writing system. It can be said that this invention is of great importance in general. According to some archaeological finds, the oldest Sumerian writing system on clay tablets dates back to the 8,000 years BC. To write on clay tablets, a Sumerian cuneiform was used, originating from pictographs and some other symbols used to display trade goods. The cuneiform was created from the need for trade because it represented a system of writing using wedge-shaped symbols, which were simpler than image symbols.
Remembering Tiananmen in Hong Kong has been viewed as an act of defiance for years, and it has become even more so now that the city’s own democratic future has come under threat. In the run-up to the 30th anniversary, demonstrators marched through the semi-autonomous enclave’s financial district chanting, “justice will prevail” and toting “support freedom” umbrellas. “In China, [people] can’t say anything against the government,” says Au Wai Sze, a nurse in Hong Kong who marched along with her 15-year-old daughter. “So while we in Hong Kong can still speak [out], we must represent the voice of the Chinese people and remind the world of this injustice.” Remembering Tiananmen in Hong Kong has been viewed as an act of defiance for years, and it has become even more so now that the city’s own democratic future has come under threat.

For all its power, China’s government is still deeply paranoid. Today, the regime is “stronger on the surface than at any time since the height of Mao’s power, but also more brittle,” Andrew Nathan, a professor of political science at Columbia University, wrote in Foreign Affairs. The people’s loyalty is predicated on wealth accumulation, which will be difficult to sustain. A sputtering economy, widespread environmental pollution, rampant corruption and soaring inequality have all fed public anxieties about Xi’s ability to continue fulfilling the prosperity-for-loyalty bargain.
Having a railroad would make transportation of goods much easier. This would also make it safer and more efficient. There were a few risks involved but far less than transporting by conventional means.
