I was asked to find the incorrect part (among the 4 reply options) in the following sentence, but I couldn't find any at all. Could you kindly help?
"After rising the flag to commemorate the holiday, the mayor gave a long speech".
b. to commemorate
c. the holiday
d. a long speech
Thank you very much in advance for your help.

The incorrect ans. is ‘a. rising’. It should be ‘raising’.
