In this task, you will be presented with a context passage, a question about that paragraph, and a possible answer to that question. The task is to check the validity of the answer. Answer with "Yes" or "No".

Example Input: Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit .  Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years .  Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes .  The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold .  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 .  The robotic probes sent out to research on Darwin IV are called Horus Probes .  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 .  The probes have a limited degree of artificial intelligence , very similar to the ` processing power ' of a 4-year-old .  All the real thinking is done by a supercomputer in the orbiting Von Braun .  The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker .  The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin .  After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter . <sep>What are the different types of probes on the Von Braun?<sep>Horus Probes
Example Output: Yes

Example Input: Dam Good Luck: From the beginning, Las Vegas was built to serve travelers. The railroad needed a way station, and Las Vegas was the place. Growth continued for ten years, and by 1915 the town had telephones, round-the-clock electricity, and a growing population — many of whom worked in the railroad repair shop. But such heady progress would soon come to a halt. The growing competition in rail transport resulted in Union Pacific buying the Los Angeles–Salt Lake line. Union Pacific then consolidated its operations, eliminating the Las Vegas repair facility. Additionally, Las Vegas had been made a part of Nevada's new Clark County in 1909, a year when the legislature also outlawed gambling. These unfortunate circumstances threatened to relegate Las Vegas to the status of a small desert community that could no longer support its 3000 residents. But the southwest's growing need for water, combined with Las Vegas's fortuitous proximity to the Colorado River, would give Las Vegas a second chance to achieve prosperity. Construction on Hoover Dam (originally Boulder Dam, subsequently renamed for the president who authorized the project) began in 1931 in a canyon 45 miles (72 km) southeast of Las Vegas. Providing an influx of $165 million to the southwestern economy, Hoover Dam played a major role in preventing Las Vegas from drying up, both financially and literally. Not only did it create jobs, but it also created Lake Mead, the massive reservoir that today provides water to all of southern Nevada. More Government Help: The construction of Hoover Dam did not single-handedly save Las Vegas, however. The state legislature helped as well, by legalizing gambling in 1931 and thus solidifying the future of the town, though legislators and residents could never have known this at the time. The hordes of people who attended Hoover Dam's 1935 dedication set the city's now-formidable public relations machine into action. They went to work on what has become one of the lengthiest citywide tourism campaigns ever attempted. It didn't take long for the city to establish itself as a wild-West town with an "anything goes" attitude. Vices outlawed or heavily controlled elsewhere were legal here, available any hour of any day (or night). <sep>What was the answer to the southwest's need for water?<sep>The Hoover Dam construction
Example Output: Yes

Example Input: Tom plays pool in a deserted pool hall , pocketing two balls by lowdown means and then wakes Jerry up by shooting the 10-ball into the pocket where he is sleeping . Jerry awakes just in time to avoid the 10-ball and is carried out to the ball return , where the 10 and the 13 smash the mouse between each other . Jerry is mad and walks up through the pocket , first sees nothing , but after a few steps back to the pocket , he spots Tom perched behind it . Jerry tries to jump into another corner pocket , but Tom aims a cue ball with so much force that it roll's into the pocket , and spins back out of it and it rolls Jerry backwards to Tom , who has made a ramp with his cue stick for the mouse to slide up . Jerry stops at the top of the stick and is then blown down by Tom , who then shoots a stream of balls to make the mouse flat . The whole train rebounds back towards the cat and the balls stack up at Tom's end of the table . Tom shoots all the balls in succession with his cue , and then tries to shoot Jerry , but the mouse hangs onto the cue tip . The cat , as if he were saying `` Have it your way '' , chalks up and shoots the 8-ball using Jerry . The mouse drops off the cue tip and then is upended by the 8-ball rolling in circles , and Tom forces Jerry to jump through the ball rack as if he were a circus performer . Tom then sets it on fire to add an additional level of torment , and when Jerry accomplishes this with poise , Tom discards the flaming rack and shoots the 8-ball across the table and back . <sep>Why did the mouse drop off the cue tip?<sep>Anything else
Example Output:
No
