As you fly from Boston to Honolulu, you will be traveling from east to west across multiple time zones. The time difference between Boston and Honolulu is 6 hours (Honolulu is 6 hours behind Boston).
Therefore, as you fly from Boston to Honolulu, you will experience a time difference. To be more specific, you will lose 5 hours because Honolulu is 5 time zones behind Boston. For example, if your flight departs Boston at 2:00 PM local time, it will arrive in Honolulu at 9:00 PM local time, but your body will feel like it is only 4:00 PM due to the time difference.
So, the correct answer is A) you lose 2 hours.
