Please help me solve this? Thanks

I only need help with the last 2 please

Which of the following statements is not true?     There is only one median for each variable.     One definition of the median states that, for an odd number of observations, the median is the middle score when scores are placed in order of magnitude.     Another term for the median is 50th percentile.     The median is generally more sensitive to (i.e., affected by) the presence of a few extreme observations than is the mean.
