Final answer:
911 is the emergency number in the US, but other countries have different numbers for emergency services, such as 112 in the European Union and 999 in the UK.
Step-by-step explanation:
The statement that 911 is the number to call to activate emergency services everywhere in the US and other countries is partly true. In the United States, 911 is indeed the universal number to call for emergency assistance. However, other countries have different emergency service numbers. For example, 112 is commonly used in European Union countries, and 999 is used in the UK. It's important for individuals to be aware of the local emergency service numbers when traveling abroad.
