A student researching the metric system has taken the following notes:
• The metric system was developed in France during the 1790s • It is based on powers of ten for easy conversion • All but three countries worldwide use the metric system • The US, Myanmar, and Liberia are the exceptions • Scientific communities worldwide use the metric system exclusively
The student wants to explain why the metric system is globally preferred. Which choice most effectively uses relevant information from the notes?
The metric system was developed in France during the 1790s.
Based on powers of ten for easy conversion, the metric system is used by all but three countries and exclusively by scientists worldwide.
The United States, Myanmar, and Liberia are the only countries not officially using the metric system.
All scientific communities worldwide use the metric system exclusively for research.
Correct Answer: B
Choice B. Easy conversion (powers of ten) and near-universal adoption explain preference.
