which are the correct sentences?

Hello!
I have to correct the mistakes and to tick the correct sentences:
1.The police are on their way.( maybe ‘is’ instead of ‘are’ but ‘are’ is the better choice-it’s about the members )
2.Only a few people has arrived.(correct)
3.The public are voting today.(correct)
4.The team is winning until half-time.(correct)
Thank you!

I have underlined the problem areas:

1.The police are on their way.– Correct. ‘Police’ is always plural.
2.Only a few people has arrived.
3.The public are voting today.(correct. ‘Is’ is also correct.)
4.The team is winning until half-time.-- The plural verb is also correct, but there is another problem.
