10. Summarize the author's message about the Celtic people's legacy. Use evidence from the text to support your answer.​
HACTEHA [7]

Answer:

The author's message about the Celtic people's legacy is that though they did not have any written account, they left a legacy of oral tales.

Explanation:

"Who were Celts?" is an article written by Amy Baskin. The article talks about the Celtic tribe and how their stories and accounts still prevail even after no accounts were written by them t first-hand.

The message that the author wants to convey concerning Celt's legacy is that though they never had any written account, their stories are still told in literature. The legacy they left was not of written account but oral account. They passed on their legacy by word of mouth.

Textual evidence:

<em>"The Celts may not have kept written records of themselves, but  thankfully, they were great storytellers. Much of their oral tradition has  been passed down from one generation to the next."</em>

Story with an twist (300 words)​
aleksklad [387]

Answer:

Mysterious Stranger

Prompt: Write a story that includes the words sunscreen, camera, and tourist.

He really did look like a tourist, with a camera around his neck and a bottle of sunscreen sticking out of his tote bag.

The portly man sat on the terrace, sipping lemonade and pretending to look at a glossy cruise brochure. His sunglasses masked his eyes, but I knew he wasn't looking at the brochure: he hadn't turned a page for the last ten minutes.

As I brought him his clam chowder, he coughed up a "thank you" and looked at me briefly. I tried not to stare at the tiny scar across his left eyebrow.

I walked back inside with my empty tray, shaking my head. He looked familiar, but I couldn't quite place him.
