You will be given a definition of a task first, then some input of the task.
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: On 9 September, "Colonel Cambodia" stated that the remaining six members of the Royal Irish patrol, who had now been held for over a fortnight, would be released only after a new government was formed in Sierra Leone. The negotiators concluded that the West Side Boys' increasingly unrealistic demands were stalling tactics rather than a serious attempt to conclude the crisis. At around the same time, the SAS teams near the West Side Boys' base reported that they had seen no sign of the captive soldiers during the four days they had been in position. There were also concerns that the West Side Boys might move further inland, and either kill the soldiers or move them to a location from which it would be more difficult for British forces to extract them. The combination of these factors led COBRA to order an assault.The operation was to commence at first light the next day, 10 September. The intervening time was spent securing the political and legal basis for the raid. Final approval was gained from Sierra Leonean President Ahmad Kabbah, and British Prime Minister Tony Blair, while the Army Legal Corps secured approval from the Sierra Leonean Police. Fordham, who had been leading the negotiations, telephoned the West Side Boys and was able to establish that the captive soldiers were alive, and the final orders were issued in the evening of 9 September.The two villages were to be assaulted simultaneously—Gberi Bana, where the Royal Irish were held, by the SAS and Magbeni by the paras. In addition to the remaining Royal Irish soldiers, the SAS were also tasked with extracting Lieutenant Musa Bangura—the patrol's SLA liaison, whose extraction was given the same priority as that of the Royal Irish—and a group of Sierra Leonean civilians who were being held by the West Side Boys.
Output:
What are the names of the two villages that were to be assaulted simultaneously?
