Answer:
An absolute phrase is a type of the phrase which modifies a noun in a sentence, but without being connected to the sentence with a conjunction. An absolute phrase is separated from the rest of the sentence by a comma, and if we remove the phrase the sentence won't lose its original meaning.
e.g. Her luggage has been packed, Sarah went to the airport.
We create an absolute sentence when we want to add some unnecessary detail to our sentence, but without changing its original meaning. In the example above, the first part of the sentence represents the absolute phrase, while the second part of the sentence contains the important information - that Sarah went to the airport.
Christopher Columbus was an Italian-Roman explorer who found the Americas on his way to Europe in the 16th century, and his voyages led to centuries of transatlantic colonization.
The period between 1492 and 1504, during the period when Columbus was exploring the Atlantic Ocean by ship, he made several ocean-going trips by ship. These trips were during the time when he explored the Atlantic Ocean by ship. It was not possible for him to establish a straight water route from Europe to Asia, despite his determination. Instead, he was lucky enough to stumble upon the Americas. His explorations marked the beginning of centuries of exploration and colonization, despite the fact that he did not discover the New World, millions of people already lived there at the time.
