You will be given a definition of a task first, then some input of the task.
In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.

Question: Which astronomical body that the US planned to build an outpost on has a bigger mass? Passage 1:In 1642, Williams, as a well connected local man and strong Protestant, was appointed by the King with a Commission of Array. At the outbreak of what was to become the First English Civil War, this gave him responsibilities for raising an army within Monmouthshire for the King, and holding the county against opposition. He was also created a baronet (one of several Williams baronets in Wales). Having set about his allotted task he was captured by Parliamentary forces in 1643 at Highnam during the Siege of Gloucester. After his release, he set about fortifying the ruined medieval stone castle at Llangibby, beside the Caerleon to Usk road, and garrisoned it with 60 men. In 1644 he helped lead operations around Monmouth. After the town was lost to the Parliamentarians he pleaded with Prince Rupert for more men and ammunition, following which he helped lead its recapture.
Passage 2:Mars Outpost is a concept for a human base on the planet Mars that was developed by the United States in the 1980s. The components and design were based on an earlier lunar test bed outpost. Development would go through several phases over four years, from an 'Emplacement Phase' to a 'Consolidation Phase', after which full use by its crew could commence. Components of the base would include a habitat module, pressurized rover dock/equipment lock, airlocks, and a constructed habitat. The 16 m habitat would be constructed in situ. Other technology for the base design includes a meteorological balloon, unpressurized rover, storage/work area, an area for geophysical experiments, and an area antenna. The Mars Outpost would be designed for a crew of 7 astronauts. Their main tasks would be to do research on mining of Mars and Phobos, life sciences, technology, and solar system exploration. The Office of Space Exploration did case studies that include establishing a human presence on another planet in 1988 and 1989. An objective of the Mars Evolution 1989 study was, "Emplace a permanent, largely self-sufficient outpost on the surface of Mars."
Passage 3:The song initially gained popularity on social video sharing app TikTok and eventually entered the Billboard charts in March 2019. The song reached number 19 on the Billboard Hot Country Songs chart before the magazine disqualified it from being included on the chart on grounds that it did not fit the genre, sparking a debate on the definition of country music. Though the song was not re-entered onto the overall country charts, both the original version of the song and the remix featuring Cyrus eventually peaked at number one on the flagship Billboard chart, the Hot 100, for a record-breaking nineteen consecutive weeks. Internationally, one or more versions of "Old Town Road" have topped the national singles charts in Australia, Canada, France, Germany, Ireland, the Netherlands, New Zealand, Norway, Switzerland, and the United Kingdom; and charted within the top ten in various other markets. Furthermore, the song was awarded diamond certification by the RIAA, in October 2019, for moving ten million total units in the United States, the fastest song to be awarded diamond certification. The remix of "Old Town Road" featuring Billy Ray Cyrus has been nominated for Record of the Year and Best Pop Duo/Group Performance at the 62nd Annual Grammy Awards, with its music video receiving a nomination for Best Music Video.
