Answer:
Eventually, the Romans using the umbrella to protect themselves from the rain as well as the sun is correct.
Step-by-step explanation:
The passage is about the evolution of the umbrella as well as the origin of the name (latin word umbra.) In sentences 10 and 11, the author presents two different uses for the umbrella. All the options use the conjunction as well to indicate these actions. This conjunction can be at the end of the sentence or in the middle to indicate in addition. In the correct answer, it is indicated one use (protect from the rain) and a second one (protect from the sun). In options 2 and 3, there is a coma after sun, and then, a noun (the Romans or the umbrella) but the position in the sentence makes them incorrect.
