Directions: Read the passage given below and answer the questions that follow by choosing the correct/most appropriate options:
The United States and China have agreed to more “responsibly” manage their increasingly fractious relations, following a meeting between Presidents Joe Biden and Xi Jinping. In their first face-to-face meeting, since Mr. Biden assumed the U.S. presidency, in Bali on November 14, 2022, ahead of the G20 summit, they appeared to agree that the downward slide in relations, especially in the wake of U.S. House Speaker Nancy Pelosi’s visit to Taiwan in August, suited neither side. The biggest takeaway is an agreement that “competition should not veer into conflict” and that both must, as the White House put it in a statement, “manage the competition responsibly and maintain open lines of communication”. Mr. Xi echoed that sentiment by saying “relations should not be a zero-sum game where one side out-competes or thrives at the expense of the other”. Starting with working together on climate change, a key challenge that cannot be addressed without the world’s two biggest polluters. U.S. Secretary of State Antony Blinken will now travel to China, while other suspended joint working groups, including on global economic stability, debt relief, food security, and health security, are likely to resume.
Which of the following statement is true as per the passage?
I: More than 30 giga-tons of CO2 are released into the Earth’s atmosphere: this is the main source of the greenhouse gases that contribute to climate change.
II: China and the United States are countries that produce the most emissions, measured in millions of tons of CO2.
III: During the last year recorded, the concentration of CO2 in the atmosphere broke another record, despite a drop in fossil fuel emissions during the Covid-19 pandemic.
