1. c - was talking (the next sentence use past tense ' I heard voices...' and the proper answer was in past continous because it was possibly in progress when the speaker heard the voice)
2. b - how long did it take you (the answer was in past tense and it's the question about duration)
3. a (interrogative form is the question form)
4. d - is driving (because the speaker says the warning now 'watch out!', so it should be in present continuous)
