Kim ___ in London before she moved to Glasgow.a) livedb) has livedc) is leavingd) had lived

To solve the question "Kim ___ in London before she moved to Glasgow," we need to analyze the context of the sentence to determine which grammatical tense is appropriate.

1. Understanding the Context
   The phrase "before she moved to Glasgow" indicates that there is a timeline where Kim lived in London at some point in the past prior to her moving to Glasgow.

2. Evaluating the Options
   a) lived - This is the simple past tense, which describes an action that was completed in the past, suitable here. b) has lived - This present perfect tense indicates an action that started in the past and continues to the present or has relevance now; it does not fit since she has already moved. c) is leaving - This present continuous tense suggests an action occurring right now, making it inappropriate for the context provided. d) had lived - This past perfect tense describes an action completed before another action in the past, which could be valid but appears more complex than necessary for this sentence structure.

3. Conclusion
   Given that the sentence refers to a completed action in the past (living in London), the best choice is (a) lived.

Final Answer

Kim lived in London before she moved to Glasgow.
