Question

form a compound sentence.
greek food uses lots of olive

oil and various herbs, such as oregano and rosemary

oil, an oil from the fruit of olive trees

oil, so greeks use six gallons per person every year

Explanation:

To form a compound sentence, we need a conjunction that shows a relationship between two independent clauses. The third option has "so", which is a coordinating conjunction used to show a cause - effect relationship. The first option is a simple sentence with additional information, and the second is a sentence with an appositive phrase. The third option combines "Greek food uses lots of olive oil" (independent clause) with "Greeks use six gallons per person every year" (independent clause) using "so" to form a compound sentence.

Answer:

oil, so Greeks use six gallons per person every year
