Answer:
please find the attached file.
Explanation:
According to the definition of a noun, the noun is the name of any person, place, or thing. 
Example: 
Ram, Shyam, Delhi, Mumbai, table, etc. 
singular noun and pural noun:
- A singular noun calls a person, place, thing, or concept, whereas an ordinary noun calls several people, places, things, or ideas.
- More than one is plural, and a noun is a word that identifies something. Therefore, plural substantives are more than one noun.
In the given sentence, the word "Our group" is part of the pural noun, and the word "New York" is write as s because it is part of singular noun.
 
        
             
        
        
        
7. C 8.D 9.D 10.A are The correct answer
        
                    
             
        
        
        
I believe the answer is (B) because (A) has an improper use of the colon, and in (C) they put the semi colon after "we" which doesnt make sense because  "We had a relaxing lunch we," is not a proper sentence.
