You will be given a definition of a task first, then some input of the task.
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).

Abstract: A procedure for the multisystem analysis of bloodstains using the simultaneous separation of the enzymes glyoxalase I, esterase D, and phosphoglucomutase has been developed. The amount of bloodstain required has therefore been reduced threefold without any loss in resolution and sensitivity. Bloodstains at least seven weeks old have been correctly phenotyped in all three systems.
Which is the apt title for the abstract? option1: The simultaneous separation of the enzymes glyoxalase I, esterase D, and phosphoglucomutase. option2: Pulsatile versus nonpulsatile blood flow in the treatment of acute cerebral ischemia.
Output:
The simultaneous separation of the enzymes glyoxalase I, esterase D, and phosphoglucomutase.
