Answer:
<u>The following is the </u><u>central idea</u><u> of the paragraph:</u>
"The first object which saluted my eyes when i arrived on the coast was the sea, and a slave ship."
<u>The following are the </u><u>supporting details</u><u> of the paragraph:</u>
"These filled m with astonishment, which as soon converted into terror when i was carried on board."
"I was immediately handled and tossed up to see if I were sound by some of the crew; and I was not persuaded that I had gotten into a world of bad spirits, and that they were going to kill me."
Explanation:
The central idea of the paragraph is when Equiano first sees the sea and the slave ship, as it is the moment that will give purpose to the rest of the paragraph; it is the main point of the narration.
The supporting details of the paragraph are what comes after the central idea, and what build up the paragraph's structure as they develop the main idea with more detailed information. In this case, the supporting details show Equiano's fear as he is taken into the ship.
