You need to read the given passage and construct a question about the information present in the passage. The question should be answerable from the passage. Most importantly, only those questions are allowed whose answers cannot be determined from a single sentence. Do not generate questions that require only a single sentence to answer. Instead, try to combine two sentences and create a question from that combination. Do not create open-ended questions, i.e., the answers to them cannot be found precisely from the information provided in the passage.
One example: Paragraph- Sent 1: A Republican bid to keep the government open past Friday includes no new money for the construction of a border wall along the U.S.-Mexico border, according to several congressional aides familiar with ongoing talks.
Sent 2: GOP leaders submitted the new offer Tuesday afternoon in an effort to appease Democrats, whose votes are needed to avert a shutdown of federal agencies, several House and Senate aides said.
Sent 3: However, Republicans also insisted on increases in border security and defense spending, including money to repair existing fencing and new surveillance technology to patrol the nearly 2,000-mile border.
Sent 4: Democrats have indicated that they would support such appropriations so long as no money goes toward an actual wall.
Solution is here: Who has to be appeased to keep the government open?
Explanation: This is a good multi-sentence question because, "appease Democrats" is mentioned in Sent 2, while "keep the government open" is part of Sent 1. As this question requires more than one sentences to answer, it's a good question.

Now, solve this: Paragraph- Sent 1: Moscow (CNN) -- Divers have completed their search of a Russian cruise ship that sank last weekend with the loss of many lives, the Emergency Situations Ministry told CNN Friday.
Sent 2: The official death toll has reached 114 -- including 66 women, 28 children and 20 men, the ministry said.
Sent 3: The bodies of 15 people are still missing.
Sent 4: There were 208 people on the "Bulgaria" at the time of the accident Sunday, of whom 79 were rescued.
Sent 5: Divers have checked all the boat's compartments, the ministry said, and are now looking for more bodies around the boat as well downstream on the Volga River, where they could have been carried by the current.
Sent 6: The area where search efforts continue has been enlarged to 200 kilometers (125 miles) from the scene, Russian Transport Minister Igor Levitin said at a briefing Friday.
Sent 7: Preparations are under way for the cruise ship to be raised from the river bottom in the coming days.
Sent 8: Two large boat cranes, one from Moscow and another one from Volgograd, which will be used for the lifting, are on the way to the accident site.
Sent 9: "We have asked the Emergency Situations Ministry to keep 23 divers at the scene to continue the search for bodies even during the lifting operation," Levitin said.
Sent 10: Specialist military divers were brought in mid-week to aid in the search efforts.
Sent 11: Four people face criminal charges over the sinking of the ship, which Russian media have called the most devastating river accident in the country's history.
Solution:
Who was brought in to aid the search?
