Please help me with this difficult problem question, thank you so much in advance!

Problem Question:

Daylight Saving Time (DST) is the practice of turning the clock ahead as warmer weather approaches and back as it becomes colder again so that people will have one more hour of daylight in the afternoon and evening during the warmer season of the year. The rationale behind the policy is to decrease the need for articial light sources and, as a result, save energy. The practice dates back centuries. In 1284, while living in Paris, Benjamin Franklin proposed the idea of shifting work hours in the summer months to maximize the use of daylight. In 1907, in Britain, William Willett advocated instituting DST because the \"bright light of an early morning during spring and summer months is so seldom seen or used." Germany adopted the practice of DST as a wartime measure to conserve energy in April of 1916, and over a dozen countries quickly followed suit. Today, the practice is followed around the globe with 123 countries having adopted it. Almost every industrialized nation of the world now employs the practice, affecting over one billion people. A portion of the upper Pripyat River flows between the countries of Ukraine and Belarus. During the months of March through May, with snowmelt and spring showers, the banks of the river overflow and threaten the local population with ooding. Starting in 2008, Ukraine installed a water diversion system on its side of the Pripyat to help channel away excess water during the ood season. In 2011, seeing how effective that system was, Belarus installed a nearly identical system. In 2012, through informal contacts between authorities in Ukraine and Belarus, the two countries began to coordinate operation of their water- diversion systems. Eventually, they synchronized the computers each country used for its system and the combined effort resulted in superior results with the risk of ooding essentially eliminated. During this time, both countries used DST, forwarding their clocks by one hour in March and setting them back in November. In 2020, Belarus decided it would no longer use DST. This had an impact on the shared water diversion system that Belarus and Ukraine had been employing since 2012. In particular, the two countries had synchronized their computers to coordinate the machinery used in diverting waters. Given the new one-hour discrepancy between the times in the two countries starting in March, there were problems caused with the computer synchronization. To deal with this problem Ukraine could have installed new computers for the diversion system but this would have been prohibitively expensive given that the country was experiencing a severe nancial crisis. In the meantime, heavy rains were forecast for that spring. Citing concerns about the shared water diversion system, Ukrainian diplomats urged their Belarussian counterparts to remain on DST. They argued that DST was a customary norm and that, in not using it, Belarus was in violation of international law. Belarus responded that it felt DST was a \"Western-imposed burden" and it would not go back to it. That spring, the region was inundated with some of the heaviest rains in decades. Because of the issues of computer synchronization, the Ukraine-Belarus water diversion system did not perform effectively and there was massive flooding of Ukrainian towns along the Pripyat River. This caused millions of dollars in property damage. Subsequent to the flooding, Ukraine has led a lawsuit against Belarus in the International Court of Justice. It is seeking damages for the ooding and an injunction ordering Belarus to return to DST. Among other grounds, Ukraine bases its lawsuit on Belarus's alleged violation of customary international law based on its non-adherence to DST. Assume the following additional facts: 0 In all its history, Belarus only used DST from 2003 through 2020 as part of a series of measures enacted to help attract foreign investment. In 2006, the President of Belarus had announced to the country's National Assembly that adoption of DST \"helped bring Belarus into the twenty- tirst century and allowed it to participate as a member of good standing in the new world order.\" In 2009, soon after receiving financial assistance from the German government, the Belarussilln National Assembly (or legislature) adopted a resolution declaring the country a \"sister state\" of the Federal Republic of Germany. Among other things, the resolution stated in its preamble that Belarus and Germany were \"kindred nations\" based on the spirit of their laws and shared institutions" and recited a number of commonalities in a bullet-point list that followed, including use of DST. Nevertheless, before 2003, on approximately a dozen occasions during the twentieth century, through public statements of its government ofcials and diplomats, as well as in dictum in a judicial decision written by its highest court, Belarus voiced its objection to using DST. o In all its history, China, a country with the world's largest population and one of its largest land masses, never adhered to DST until 1986. It tried it for five years and then abandoned it. India, with the world's second largest population and one of its largest land masses, only used DST from 1942-45. Russia, with the world's largest land mass, has used DST for years and is now on DST year-round. All of Europe is on DST except for Iceland and Belarus. 0 In the Northern Hemisphere, those countries that have adopted DST use it during their spring and summer [April to October). In the Southern Hemisphere, DST countries adopt the practice in their spring and summer (October to March). And countries in the equatorial tropics, having no need for it, do not adopt the practice at all. u The International Aviation Transportation Convention of 2013, which sets transnational standards for air trafc safety controls, and to which 140 nations are party, including Belarus and Ukraine, stipulates that all members will use DST. The W countries that do not currently use DST, excluding Belarus, have made public statements to the effect that they will amend their laws to adopt DST to be in compliance with their legal obligations. After considering these facts, as a class, we will answer the questions below. Please consider opposite sides (i.e., one answer supporting \"yes" and one answer supporting \"no\") for each question. And please consider whether you can nd support for these answers from the relevant passages of the cases we have analysed on customary international law. The questions are as follows
