Answer:
The correct answer is: It describes how China's government has used physical and virtual walls to protect itself through the history.
Explanation:
The main idea of the article ''Like the Great Wall, the Great Firewall may not be able to protect China's government forever" describes the systematic separation of China from the rest of the world by using physical and virtual walls to protect themselves from foreign influences. This statement refers to the fact that China blocks almost all foreign media, human rights groups or websites which considers harmful for its citizens.
These walls were a great way of defense through history, but, today, with today's technology development, those walls probably will not be strong enough to protect the country from foreign influences and new trends.
As one president’s term ends and another begins, there is a ceremony. Its importance is one of symbolism rather than substance. The Constitution is clear: On Jan. 20, there will be a transfer of power. There is no mention of an inauguration.
By definition, ritual acts have no direct effect on the world. A ceremonial event is one that symbolically affirms something that happens by other, more direct means. In this case, the election – not the inauguration – makes the president, although an oath is required before exercising his power.
Nonetheless, ceremonies matter. Having spent two decades studying ritual, I can attest to that. So can the recent history of inaugurations: In 2009, Barack Obama misplaced one word when reciting the presidential oath of office. As a result, he decided to retake the oath the next day. And in 2017, Donald Trump insisted that his inauguration was attended by a record-setting crowd, even as everyone’s eyes saw otherwise. He saw the size of the attendance as a measure of his legitimacy.
