A man talking into a microphone with a woman standing next to him.
There are people giving a speech at the fair.
Just because a man is talking into a microphone does not mean that he is giving a speech, or that he is at a fair.
Might be a special occasion that the people are participating in giving speech and speeches can be given anywhere not only at the fair.
Talking on a microphone could be done anywhere not necessarily at a fair or be a speech, it could be as simple as a man answering questions on the news.
