DIA [1.3K]

Step-by-step explanation:

Let's first arrange it in ascending order :

340, 480, <u>560</u>, 680, 700

<u>560</u> is clearly the median.

Now add an additional score of 700 to the data :

340, 480, <u>560, 680</u>, 700 ,700

<u>560, 680</u> is separating both halves but is not the median

Median  = 620
