To determine which option is correct, we need to clarify the phrase "his younger brother's mean." It seems to imply that Jeremiah is at the average height of his younger brother's height, but it's not entirely clear.
Let's analyze the options based on different interpretations:
- If "mean" refers to average, then Jeremiah's height is equal to the average height of his younger brother, meaning he is neither taller nor shorter.
- If we interpret "his younger brother's mean" to suggest his height is less than, equal to, or greater than his younger brother's height, we can conclude:
Without further context about the younger brother's height, we can't definitively choose any of the first three options. Therefore, the most reasonable answer given the ambiguity is:
D, none.
However, if you have additional context that specifies the height of the younger brother, please provide it for a more accurate determination.
