Answer:
The four subject-verb disagreements are:
Organizers/reports
places / has
They / was
awards ceremonies / will occur
Step-by-step explanation:
Organizers is a plural noun and reports is a verb in a simple present sentence with the conjugation of the third person, places and has followed the same error since it is a plural noun with a third person conjugation, and this error continues to they and was, the last mistake uses two words in plural in the noun which is not possible since it should be the awards ceremony.
