Identify the pair that represents the same relationship as "High: Low".

The relationship represented by "High: Low" is one of opposites or antonyms, where "high" is the opposite of "low." This kind of relationship is characterized by contrasting concepts that are directly related in meaning but stand at opposite ends of a spectrum.

The choice "Up and Down" shares this same relationship, as "up" signifies a direction or position higher than a reference point, while "down" indicates a position that is lower. Both pairs convey a similar contrasting relationship, making this choice the correct one.

In contrast, the other pairs do not exhibit a direct antonym relationship. “Cricketer and Football” pertains more to different sports or professions, while “Doctor and Engineer” refers to different career paths that do not stand in opposition to one another. Thus, they do not capture the same type of contrasting relationship as "High: Low."
