Answer:
The four subject-verb disagreements are:
Organizers of the very first race reports
500 Of the 15,000 places has now sold out,
They was first released to the public.
Where the official awards ceremonies will occur
Step-by-step explanation:
The question is not complete since it does not provide the complete paragraph, here is the complete paragraph
Organizers of the very first Lake Garda race report that all but 500 of the 15,000 places has now sold out, just a month after they was first released to the public. For anyone itching to be the very first winner, there are only days left to get your entry in. Prices range from £35 to £55, with riders attempting either of two challenges: a gruelling, 104-mile event that covers the most difficult terrain, or as lightly less testing, but no less enjoyable, 52-mile contest that winds its way along the scenic shores of Lake Garda on April 12th/13th. Starting near the port, both events will conclude in the picturesque lakeside town of Brenzone where the official awards ceremonies will occur.
There is a subject-verb disagreement when the conjugation that is being used is not the correct one for the subject in the sentence, this is a common mistake among plurals, third person and singular subjects. The errors or disagreements that are in this paragraph should be revised as:
1.-Organizers report
2.-places have
3.-They were
4.- Awards ceremony will occur.
