Toughness', 'role': 'user'}, {'content': 'Answer: B \nExplanation: Popularly, the term resilience is associated with springiness, but it means precisely the\xa0amount\xa0of\xa0energy\xa0absorbed\xa0within\xa0a\xa0unit\xa0volume\xa0of a structure when it is stressed to its proportional limit. The resilience of two or more materials can be compared by observing the areas under the elastic region of their stress-strain plots assuming that they are plotted on the same scale. The material with\xa0 the larger elastic area has the higher resilience.\nPhillips dental materials 12th edition page no 55', 'role': 'assistant'}]
