Instructions: 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.
Input: Question: Which nutrient that Goodale focused on during her research has a higher atomic mass? Passage 1:South Park is a first-person shooter adventure video game based on the American adult animated sitcom of the same name. The game was developed by Iguana Entertainment and published by Acclaim Entertainment for the Nintendo 64 in 1998 for North America and in 1999 for Europe. It was later ported to Microsoft Windows in 1999 and released in North America only. The PlayStation port was developed by Appaloosa Interactive in 1999. A Game Boy Color version developed by Crawfish Interactive was in development, but it was eventually cancelled due to South Park creators Matt Stone and Trey Parker stating that the game would not be fitting on the Game Boy Color as that console was marketed towards children. However, they did keep a few copies of the Game Boy Color version to commemorate what was originally started as the first South Park game. Despite the Nintendo 64 version's positive reception, the PC and PlayStation versions of South Park were panned by critics. A Sega Dreamcast version was planned for a 2000 release, but was cancelled during development for unknown reasons. In 2018, a ROM image of the Game Boy Color version was leaked online.
Passage 2:Christine Goodale's official fields of research are ecology and evolutionary biology as well as Soil and Crop Sciences. She has experience in a wide variety of scientific topics, including acid rain, carbon sequestration, climate change, forest ecosystems, nitrogen cycling and retention, and watershed processes. Goodale is an ecosystem ecologist whose research focuses mainly on forest ecosystems, including the role that forests play in important water cycle processes and regulation of atmospheric greenhouse gases, as well as the impacts that afflict forest ecosystems as a result of human activities. Goodale specifically focuses on nutrients like carbon and nitrogen, and her lab is dedicated to understanding the impact that elevated nitrogen levels have on forest ecosystem processes, and the way that these ecosystems manage the excess nitrogen. Goodale and her team examine these impacts across multiple spatial and temporal levels, from plots in a watershed to whole continents, utilizing a combination of field studies, ecosystem modeling, and acquired regional data sets to help answer their main research questions. Her past research has taken place mainly in the forests of the Northeastern United States, primarily forests in the White Mountains of New Hampshire and central New York.
Passage 3:The natural satellites orbiting relatively close to the planet on prograde, uninclined circular orbits (regular satellites) are generally thought to have been formed out of the same collapsing region of the protoplanetary disk that created its primary. In contrast, irregular satellites (generally orbiting on distant, inclined, eccentric and/or retrograde orbits) are thought to be captured asteroids possibly further fragmented by collisions. Most of the major natural satellites of the Solar System have regular orbits, while most of the small natural satellites have irregular orbits. The Moon and possibly Charon are exceptions among large bodies in that they are thought to have originated by the collision of two large proto-planetary objects (see the giant impact hypothesis). The material that would have been placed in orbit around the central body is predicted to have reaccreted to form one or more orbiting natural satellites. As opposed to planetary-sized bodies, asteroid moons are thought to commonly form by this process. Triton is another exception; although large and in a close, circular orbit, its motion is retrograde and it is thought to be a captured dwarf planet.
