Yes that could be a survival reference
The amount of rose flowers that the store managed to sell in one month is 1,470. Out of the total amount of 2,450 sold flowers in the month, one percentage comes at 24.5 flowers, that multiplied by 60 gives us the required number for 60%, and that comes at 1,470 rose flowers sold.
Answer:
I'm pretty sure the answer would be sentence number 8
Explanation:
This is the start of a new paragraph, and it uses the pronoun "they" for Noel and his friend. The reader might forget who "they" is by this point. In the next sentence the author uses "they" again. It's not exactly precise to use they twice in a row like that because again, the reader might forget who they is referring to. Sentence 8 should say Hami and Noel, instead of they, and then it would be perfectly fine to use they in the next sentence.
Hope that helps :)
