By examining the beetle fossils, a research team provided the most detailed description of the temperature in the United Kingdom over the past 22,000 years to date. The research team selected existing biological fossils and set their dates. When found in the same place When individuals of several organisms found belong to the same time period, the known endurance temperature of existing beetles can be used to determine the highest summer temperature in that place during that time. Which of the following hypotheses does the researcher's argument depend on? ['Beetles are more resistant to warm weather than cold weather.', 'Fossils of different species found in the same place belong to different periods.', 'The method of determining the date of the beetle is more accurate than the method of determining the date of other organisms.', 'There has been no significant change in the tolerable temperature of beetles during the past 22,000 years.']
