Question: what is the percent relationship of Catalan to the language spoken in the land near the thermal worm's first known location?

full_context: Document 1: San Cristóbal Island: The largest fresh water lake in the archipelago, Laguna El Junco, is located in a crater in the highlands of San Cristóbal, in the southern half of the island. The lake harbors a large population of birdlife, but reaching the lake requires a short uphill walk.  Nearby, La Galapaguera is a breeding station and sanctuary for giant tortoises.

Document 3: Languages of the Falkland Islands: The only official language of the Falkland Islands is English, and this is spoken by almost everyone on a day-to-day basis. Spanish is spoken by 10% of the population, a significant minority. Most of the Spanish speakers are immigrants, foreign workers, and expats, predominantly from Chile and Argentina.
Document 4: Catalan language: According to Ethnologue, the lexical similarity between Catalan and other Romance languages is: 87% with Italian; 85% with Portuguese; 80% with Spanish; 76% with Ladin; 75% with Sardinian; and 73% with Romanian.
Document 5: Annelid: Earthworms are Oligochaetes that support terrestrial food chains both as prey and in some regions are important in aeration and enriching of soil. The burrowing of marine polychaetes, which may constitute up to a third of all species in near-shore environments, encourages the development of ecosystems by enabling water and oxygen to penetrate the sea floor. In addition to improving soil fertility, annelids serve humans as food and as bait. Scientists observe annelids to monitor the quality of marine and fresh water. Although blood-letting is no longer in favor with doctors, some leech species are regarded as endangered species because they have been over-harvested for this purpose in the last few centuries. Ragworms' jaws are now being studied by engineers as they offer an exceptional combination of lightness and strength.
Document 6: Catalan language: Catalan (/ˈkætəlæn/; autonym: català [kətəˈla] or [kataˈla]) is a Romance language named for its origins in Catalonia, in what is northeastern Spain and adjoining parts of France. It is the national and only official language of Andorra, and a co-official language of the Spanish autonomous communities of Catalonia, the Balearic Islands, and Valencia (where the language is known as Valencian, and there exist regional standards). It also has semi-official status in the city of Alghero on the Italian island of Sardinia. It is also spoken with no official recognition in parts of the Spanish autonomous communities of Aragon (La Franja) and Murcia (Carche), and in the historic French region of Roussillon/Northern Catalonia, roughly equivalent to the department of Pyrénées-Orientales.
Document 7: Southern Europe: The most widely spoken family of languages in southern Europe are the Romance languages, the heirs of Latin, which have spread from the Italian peninsula, and are emblematic of Southwestern Europe. (See the Latin Arch.) By far the most common romance languages in Southern Europe are: Italian, which is spoken by over 50 million people in Italy, San Marino, and the Vatican; and Spanish, which is spoken by over 40 million people in Spain and Gibraltar. Other common romance languages include: Romanian, which is spoken in Romania and Moldova; Portuguese, which is spoken in Portugal; Catalan, which is spoken in eastern Spain; and Galician, which is spoken in northwestern Spain.
Document 8: Symbiosis: One of the most spectacular examples of obligate mutualism is between the siboglinid tube worms and symbiotic bacteria that live at hydrothermal vents and cold seeps. The worm has no digestive tract and is wholly reliant on its internal symbionts for nutrition. The bacteria oxidize either hydrogen sulfide or methane, which the host supplies to them. These worms were discovered in the late 1980s at the hydrothermal vents near the Galapagos Islands and have since been found at deep-sea hydrothermal vents and cold seeps in all of the world's oceans.
Document 9: Catalan language: Catalan shares many traits with its neighboring Romance languages. However, despite being mostly situated in the Iberian Peninsula, Catalan differs more from Iberian Romance (such as Spanish and Portuguese) in terms of vocabulary, pronunciation, and grammar than from Gallo-Romance (Occitan, French, Gallo-Italic languages, etc.). These similarities are most notable with Occitan.
Document 10: Dialect: In addition to having evolved, for the most part, separately from one another and with distinct individual histories, the Latin-based regional Romance languages of Italy are also better classified as separate languages rather than true "dialects" due to the often high degree in which they lack mutual intelligibility. Though mostly mutually unintelligible, the exact degree to which the regional Italian languages are mutual unintelligible varies, often correlating with geographical distance or geographical barriers between the languages, with some regional Italian languages that are closer in geographical proximity to each other or closer to each other on the dialect continuum being more or less mutually intelligible. For instance, a speaker of purely Eastern Lombard, a language in Northern Italy's Lombardy region that includes the Bergamasque dialect, would have severely limited mutual intelligibility with a purely standard Italian speaker and would be nearly completely unintelligible to a speaker of a pure Sicilian language variant. Due to Eastern Lombard's status as a Gallo-Italic language, an Eastern Lombard speaker may, in fact, have more mutual intelligibility with a Occitan, Catalan, or French speaker than a standard Italian or Sicilian language speaker. Meanwhile, a Sicilian language speaker would have an greater degree of mutual intelligibility with a speaker of the more closely related Neapolitan language, but far less mutual intelligibility with a person speaking Sicilian Gallo-Italic, a language that developed in isolated Lombard emigrant communities on the same island as the Sicilian language.
Document 11: Symbiosis: Symbiotic relationships include those associations in which one organism lives on another (ectosymbiosis, such as mistletoe), or where one partner lives inside the other (endosymbiosis, such as lactobacilli and other bacteria in humans or Symbiodinium in corals). Symbiosis is also classified by physical attachment of the organisms; symbiosis in which the organisms have bodily union is called conjunctive symbiosis, and symbiosis in which they are not in union is called disjunctive symbiosis.
Document 12: Predation: Parasites can at times be difficult to distinguish from grazers. Their feeding behavior is similar in many ways, however they are noted for their close association with their host species. While a grazing species such as an elephant may travel many kilometers in a single day, grazing on many plants in the process, parasites form very close associations with their hosts, usually having only one or at most a few in their lifetime. This close living arrangement may be described by the term symbiosis, "living together", but unlike mutualism the association significantly reduces the fitness of the host. Parasitic organisms range from the macroscopic mistletoe, a parasitic plant, to microscopic internal parasites such as cholera. Some species however have more loose associations with their hosts. Lepidoptera (butterfly and moth) larvae may feed parasitically on only a single plant, or they may graze on several nearby plants. It is therefore wise to treat this classification system as a continuum rather than four isolated forms.
Document 13: Galápagos Islands: The Galápagos Islands (official name: Archipiélago de Colón, other Spanish name: Las Islas Galápagos, Spanish pronunciation: (las ˈiɦla ɣaˈlapaɣo)), part of the Republic of Ecuador, are an archipelago of volcanic islands distributed on either side of the Equator in the Pacific Ocean surrounding the centre of the Western Hemisphere, 906 km (563 mi) west of continental Ecuador. The islands are known for their vast number of endemic species and were studied by Charles Darwin during the second voyage of HMS Beagle, as his observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection.
Document 14: Symbiosis: The definition of symbiosis has varied among scientists. Some believe symbiosis should only refer to persistent mutualisms, while others believe it should apply to any type of persistent biological interaction (in other words mutualistic, commensalistic, or parasitic). After 130 years of debate, current biology and ecology textbooks now use the latter "de Bary" definition or an even broader definition (where symbiosis means all species interactions), with the restrictive definition no longer used (in other words, symbiosis means mutualism).
Document 15: Galápagos Islands: The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000.
