2) In - Again, "in" is used to indicate being located or present in a specific place. In this sentence, it means being away from home or in a different time zone.

3) In - "In the morning" means during the morning hours. Since the person is experiencing jet lag, their body feels like it's morning, even though it might be night time in the place they are in.

4) To - "Go to a country" means to travel to a country. In this sentence, it indicates traveling to a country where the time is different.

5) At - "At midday" means at noon or 12 o'clock during the day. So the person is leaving London at noon.

11) In - "In London" means being in or located in the city of London. The person's body clock still thinks it's in London, despite being in Los Angeles.
