Step-by-step explanation:
All of the given scenarios could have a negative impact on a local economy, but the one that would likely have the greatest negative impact is option D, where a pandemic forces the cancellation of international travel to most of Europe.
This is because the impact is not just limited to a particular location or industry, but it affects a large portion of the economy that relies on international travel, such as airlines, hotels, restaurants, and tourist attractions. This can result in job losses, decreased revenue, and financial hardships for individuals and businesses that rely on tourism.
Option A, where a bacterial overflow forces the closing of beaches along the entire east coast of the country, would also have a significant impact on local economies that rely on tourism, but it is not limited to a particular region or industry.
Option B, where a fire causes the temporary closing of a restaurant in a major tourist destination, would have a negative impact on the restaurant's revenue and possibly its employees, but it is a more localized impact compared to the other options.
Option C, where a hurricane causes damage and loss of power to a beach town that relies on tourism, would have a negative impact on the town's tourism industry, but the impact may be temporary, and there may be assistance available for recovery efforts.
