Question

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

• A. for
• B. since
• C. from
• D. within

Hint:

Use “for” + duration (e.g., for 5 years), and “since” + starting point (e.g., since 2010).

Answer 1

The Correct Option is A

"For" is used when referring to a duration of time. Since “a decade” represents a period, "for" fits best. "Since" would require a specific starting point like "2010".
