This looks like an exercise to practice past continuous tense to describe a sequence of activities at specific times. Below is one coherent way to complete the sentences using was/were + verb-ing. Note that many variants are possible depending on the context.
Completed version (one plausible set)
- At 7:10 Mr. Anderson was taking a shower.
- At 7:15 Mrs. Anderson was brushing her teeth.
- At 8:15 Mr. and Mrs. Anderson were having breakfast.
- At 10:00 Mr. Anderson was reading the newspaper.
- At 11:00 Mrs. Anderson was answering the phone.
- At 12:30 Mr. Anderson and Mrs. Anderson were having lunch.
- At 1:30 Mrs. Anderson was taking a nap.
- At 3:30 Mrs. Anderson was cleaning the kitchen.
- At 4:30 Mr. Anderson and Mrs. Anderson were getting ready to go out.
- At 8:00 Mr. and Mrs. Anderson were watching a movie.
- At 12:30 a.m. Mr. and Mrs. Anderson were sleeping.
Notes and tips
- Use past continuous (was/were + verb-ing) for actions in progress at a specific time.
- For multiple subjects (Mr. and Mrs. Anderson), use were (e.g., were having, were watching).
- 12:30 a.m. is typically written as 12:30 a.m. (with periods) in American usage.
- Punctuation: each line forms a complete sentence; end with a period.
If you want, I can tailor the verbs to a specific daily routine you have in mind, or provide an alternative set of completions.
