Detailed Instructions: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
Problem:Abstract: Trace metal ratios in human bones were examined to determine if there were ratios that were sufficiently consistent within an individual yet varying sufficiently from the bones of another individual so that bones in a mixed grave could be reassembled. The concentrations of 21 elements sampled at 54 places on 30 human bones in each of 5 skeletons indicated that the magnesium/zinc ratio was the most reliable and that the zinc/sodium, magnesium/sodium, and chromium/sodium ratios could be used as supplements to help reassemble human bones belonging to the same individual after all standard techniques had been used.
Which is the apt title for the abstract? option1: Reassembling scattered and mixed human bones by trace element ratios. option2: Quality of life in patients 2 to 4 years after closed head injury.
Solution:
Reassembling scattered and mixed human bones by trace element ratios.
