Lucy, the skeleton of a female hominin species, was discovered in 1974 in Africa. Scientists think the skeleton is about 3. 2 million years old. For six years, Lucy' s remains were part of an exhibition called Lucy' s Legacy: The Hidden Treasures of Ethiopia. However, there was much opposition to the exhibition for fear that Lucy' s fossils would be damaged. It' s a good thing that they started using casts instead; the preservation of these fossils should be the number one concern of excavators and scientists. Which of the following would be used in opposition to the passage? ["Lucy's fossils, if they are kept in exhibition for too long, are certainly at risk for damage. Even if you can't see it with the naked eye, the constant handling of fossils will cause wear and tear that time could never recover.", 'Some scientists think that Lucy died from falling out of a tree, although they are not sure. There is also a tooth mark on top of a left pubic bone. What\'s even more curious is Lucy\'s age. Although she was considered "fully mature, " Lucy only lived for about twelve years.', 'The exhibition of Lucy is an important step in raising an awareness of where humans originated and the studies thereof. Keeping the fossils isolated from the public will certainly preserve the remains; however, we might risk the deterrence of public knowledge.', "The controversy over the exhibition of Lucy's bones is irrelevant. Even if the bones are damaged, we have preserved the memory with scans, photographs, as well as accurate castings of the fossils. Scientists are making a huge deal over something that doesn't matter in the long run."]
