Which of the following statements correctly compares and contrasts a-priori and a-posteriori methods of reference individual selection? 1. In both methods, exclusion and partitioning take place after sampling and analyte testing. 2. A-priori methods require fewer reference individuals to be studied than a-posteriori methods. 3. Questionnaires for potential reference individuals must be more detailed for a-posteriori methods than for a-priori methods.

Consider the separation of Hb 1, Hb 2, and Hb 3 by cation-exchange HPLC. The initial mobile phase pH causes Hb 1 to have the greatest positive charge, Hb 2 to have minimal positive charge, and Hb 3 to be neutral. Predict the order of elution from the stationary phase as the chromatographic run continues from the initial mobile phase to mobile phases with increasing concentrations of cations. (first to elute to last to elute)
