Solution:

• 1. c) every day - This implies a habitual action in the present simple tense, which fits the context of listening to music daily.
• 2. a) now - The present continuous tense is typically used to describe actions happening at the moment of speaking, hence 'now' is the most appropriate adverb.
• 3. a) just - 'Just' is used with the present perfect to indicate that an action happened very recently. 'I have just made a cake' means the cake was made a short time ago.
• 4. a) yesterday - The sentence 'She was sitting in the library' is in the past continuous tense, indicating an action that was in progress at a specific time in the past. 'Yesterday' provides that past time reference.
• 5. a) next week - The sentence 'I will play tennis' is in the future tense. 'Next week' is a common time expression used to indicate a future event.
• 6. b) last year - The sentence 'I worked for a company in Norway' uses the simple past tense, indicating a completed action in the past. 'Last year' provides a specific past time frame.
• 7. c) usually - 'Usually' is an adverb of frequency that indicates a regular or habitual action. The sentence 'They go away on holidays' describes a typical or usual activity.

Final Answer:

• 1. c) every day
• 2. a) now
• 3. a) just
• 4. a) yesterday
• 5. a) next week
