Which one sentence from passage 2 best explains why some of the olympic events had to change?
".modem pentathlon competitors are highly skilled-both physically and mentally-as they
work their way through these unique competitions."
"this event started in the early 1900s, and it is a highly competitive and rule-oriented race
the participants must have one foot on the ground at all times or they are disqualified
yet, there are several odd events that never got much approval or coverage."
the entire event occurred on one day, and the rules varied (for example, when participants
wrestled, they were not allowed to bite their opponent, but broken arms and disfigured
faces were often consequences of these matches)
