○ d. the si system, which is based on the metric system, has been more widely adopted than the english system, which is harder to use.

□ mark for review (will be highlighted on the review page)

Explanation:

• Option A: Europe mainly uses the SI (metric) system, not the English system, so A is wrong.
• Option B: The SI system is preferred in scientific/technical communities for its consistency (base - 10, easy conversions), not the English system, so B is wrong.
• Option C: The two systems are not used interchangeably in scientific/technical fields; SI is dominant, so C is wrong.
• Option D: The SI system (metric - based) has a base - 10 structure (e.g., 1 meter = 100 centimeters) making conversions easy, and it's more widely adopted globally. The English system (e.g., feet, pounds) has non - intuitive conversions (1 foot = 12 inches, 1 pound has complex relationships), so it's harder to use. Thus, D accurately describes the difference.

Answer:

D. The SI system, which is based on the metric system, has been more widely adopted than the English system, which is harder to use.
