Best practice
When using "extend throughout", ensure the subject logically can cover the specified area or period. For instance, "the subway lines extend throughout the city" is logical, while "the rumor extends throughout the city" may need more context (like "social circles").
Common error
Avoid using "extend throughout" when a simple "extend to" or "include" would suffice. "The offer extends throughout all customers" is less precise than "The offer extends to all customers" because the "throughout" implies something spatially or temporally expansive when it may not be.
