Answer:
From first to last, step wise is given below-
Tropical disturbance < Topical depression < Tropical storm < Wind speed above 74 miles per hour
Explanation:
In order to form a hurricane, at first, the disturbances occur in the tropical region, which is characterized by the occurrence of heavy storm activity over a large area extending 100 miles, that exist for about 24 hours.
Then, with the more favorable conditions, the disturbances alter into stronger storms that spin forming a low-pressure center, and this condition refers to the tropical depression. The required amount of humidity is present in both the upper and lower portion of the atmosphere.
The pressure within the center of the tropical depression eventually gets down, and the air flows inward, thereby forming more stronger winds. With more decreasing pressure, the wind speed drastically increases. Thus, the storm becomes stronger.
When the speed of the wind becomes 74 mph or exceeds, then this type of storm is called a hurricane.

The correct answer is - The Roman civilization.

With their arrival, the Romans brought lots of things from their society, including alphabet, thus reading and writing, they started to create cities with solid defense systems, and gradually were building roads in order to connect the cities they've built in order to enable better and quicker communication between them. Also, they introduced the Christianity in Britain. It is debatable about the exact time, there are some sources that claim that it was introduced as early as the 1st century AD, but officially it is considered that there was enough mass of people and preachers in period of the 3rd and 4th centuries so that it can be considered as a living, practiced, and prospering religion.
