Someone sent me a sentence which reads "Large numbers of people is protesting outside." and asked me to correct it. I wrote "A large number of people are protesting outside." to him. The next day, he sent me a message and said that his teacher told him that "Large numbers of..." is a correct expression. But I always hear "A number of people are...", not "Numbers of people are..." I would like your confirmation. Thanks a lot. Anais p.s. Happy New Year to you all!
