Question

Select the option that best fills in the blank and completes the sentence given below.
The two families have known each other__ a decade now.

• A. for
• B. before
• C. since
• D. of

Hint:

When referring to the duration of an action, use "for" (e.g., for a decade) and "since" to refer to a starting point (e.g., since 2000).

Answer 1

The Correct Option is A

The correct preposition is "for," which is used when referring to the duration of time. "Since" would indicate a specific starting point, while "before" and "of" do not fit the context.
