Thanks for the corrections and remarks.

Now I'd like to go back to the original sentences. Are all of them using Defining Clauses?:



The woman who "or" that is sitting in front of you now is a Junior Manager in our Headquarters.







The letter that "or" which you sent to our customers last week contained


three spelling errors.




Peter read the report that "or" which showed the figures.




I am visiting the plant that "or" which was having production problems.




The chief spent some time with workers who "or" that answered his questions.




I have been invited by a colleague who "or" that has moved to Canada.




The person who "or" that "or" Ø Anne introduced me to is keen on collecting postcards .




Where can I find a shop that "or" which sells decent coffee?.




I have found many problems that "or" which need to the solved.




I finally could speak to the clerk whose report helped me a lot in my Annual


Summary.

Thanks in advance
renan torres-riveroNow I'd like to go back to the original sentences.
Hmm. In what sense are these the "original" ones? They don't look the same.
renan torres-riveroAre all of them using Defining Clauses?
Yes. And they're all fine. Emotion: smile

Site Hint: Check out our list of pronunciation videos.
could you tell me if these sentences can be defining or non defining?

Peter hated eating by himself. He hoped to have lunch with Ann.

Peter, who hated eating by himself, hoped to have lunch with Ann.

Can this one be defining as well?

The Amazing Alarm was invented in 1882. It doesnt make any noise.

The Amazing Alarm, which was invented in 1882, doesnt make any noise.

The amazing alarm, which doesnt make any noise, was invented in 1882.
all are non-defining
Yes, they are all non-defining.

The nouns they refer to are all proper nouns.

When using common nouns (house, table, mice, etc) we are normally required to use defining clauses.
