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.
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.
Example solution: Who has to be appeased to keep the government open?
Example 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.

Problem: Paragraph- Sent 1: Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth 's orbit .
Sent 2: Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years .
Sent 3: Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , which looks for potential landing sites for the probes .
Sent 4: The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold .
Sent 5: Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species .
Sent 6: The robotic probes sent out to research on Darwin IV are called Horus Probes .
Sent 7: Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , which is covered with solar receptors , a computer ` brain ' , a ` head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves .
Sent 8: The probes have a limited degree of artificial intelligence , very similar to the ` processing power ' of a 4-year-old .
Sent 9: All the real thinking is done by a supercomputer in the orbiting Von Braun .
Sent 10: The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker .
Sent 11: The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin .
Sent 12: After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

Solution: Which interstellar spacecraft reaches Darwin IV in 42 years?
