¿Cuántos habitantes de Lone Pine sobrevivieron a consecuencia del terremoto? Dime cómo has llegado a esa conclusión.
El terremoto se produjo un martes por la mañana y arrasó casi todos los edificios de Lone Pine y los asentamientos cercanos Se sabe que de los 250-300 habitantes de Lone Pine, 27 perecieron y 52 de las 59 casas quedaron destruidas. Un informe afirma que los principales edificios fueron derribados en casi todos los pueblos del condado de Inyo. A unos 130 kilómetros (81 mi) al sur de Lone Pine, en Indian Wells, las casas de adobe sufrieron grietas. Las pérdidas materiales se han estimado en 250.000 $ (equivalentes a 5.654.861 $ en 2021). Como en muchos terremotos, las estructuras de adobe, piedra y mampostería salieron peor paradas que las de madera, lo que provocó el cierre del cercano Campamento Independencia, que era una estructura de adobe destruida en el terremoto.
Se calcula que entre 223 y 273 habitantes de Lone Pine sobrevivieron al terremoto.

El pasaje indica que había "unos 250-300 habitantes de Lone Pine" y que "se sabe que perecieron 27". Si restamos 27 a 250, obtenemos 223, y si restamos 27 a 300, obtenemos 273. Por lo tanto, se puede estimar que el número de habitantes que sobrevivieron al terremoto está entre 223 y 273.
How many inhabitants of Lone Pine survived as a result of the earthquake? Tell me how you came to that conclusion.
The earthquake occurred on a Tuesday morning and leveled almost all the buildings in Lone Pine and nearby settlements.[4] Of the estimated 250–300 inhabitants of Lone Pine, 27 are known to have perished and 52 of the 59 houses were destroyed. One report states that the main buildings were thrown down in almost every town in Inyo County. About 130 kilometers (81 mi) south of Lone Pine, at Indian Wells, adobe houses sustained cracks. Property loss has been estimated at $250,000 (equivalent to $5,654,861 in 2021). As in many earthquakes, adobe, stone and masonry structures fared worse than wooden ones which prompted the closing of nearby Camp Independence which was an adobe structure destroyed in the quake.
It is estimated that between 223 and 273 inhabitants of Lone Pine survived the earthquake.

The passage shows that there was "an estimated 250–300 inhabitants of Lone Pine" and that "27 are known to have perished". If we subtract 27 from 250, you get 223, and if we subtract 27 from 300, we get 273. Therefore, it can be estimated that the number of inhabitants that survived the earthquake is between 223 and 273.
