need help on the following interview questions

Hi group ,

1) what happens when a switch receives a TCN BPDU'S ?
2) Difference between flooding and broadcasting ?
3) does a cisco 3750 switch supports MLS and MQC QOS ?

my answers :
1) Receiving switch replicates the TCN bpdu and sends it out of its root
port , (after acknowledging the downstream bridge ) until the root bridge is
hit by TCN bpdu

 2) one and the same
3) yes

plz give me precise answers for the above questions , and more detailed
answer to q 1 he was referring to mac flushing..
