Answer:
7A.M or 8A.M base on the season at the same day.
Step-by-step explanation:
+ Greenwich is (GMT 0) during winter . During summer, a time changes and England changes the time, so it becomes (GMT +1)
+ Manaus is (GMT-4)
Therefore, it is going to be 4 or 5 hours backwards from Greenwich. When it’s 12pm in Greenwich it is 7am in Manaus during summer, and 8am during winter.
