For piano, if a dotted half note is slurred, with another dotted half note....?

Question

does that mean we hold the note for 3 beats or 6 beats?

Answer 1

Yes, 6 beats because 3+3=6. :)

Answer 2

You hold the note for 6 beats because 1 dotted half note would be 3 beats, so when you slur it there's no break, so it would be 6 beats.

Answer 3

This is a joke?

Answer 4

Six beats because the two dotted half notes are connected. One of them would be three beats, so the two together are six beats.
