Answer:
"In groves all around Basra grow the best dates in the world"
Step-by-step explanation:
The author is giving their opinion on the dates in Basra and how they think it is the best in the world. This is Subjective because they are stating what they think about the middle east and not already proven facts about it. Some might say the best dates in the world come from some place different but this is where the author thinks the best dates are.
