Provide examples of pre-determiners in sentences.

Pre-determiners are words that come before determiners and modify them. They provide additional information about the noun phrase. Here are some examples of pre-determiners used in sentences:

1. "Both of my sisters are doctors." (The pre-determiner "both of" modifies the determiner "my" and provides additional information about the noun phrase "my sisters.")

2. "Half the students in the class are from different countries." (The pre-determiner "half" modifies the determiner "the" and provides additional information about the noun phrase "the students in the class.")

3. "All the little children were playing in the park." (The pre-determiner "all the" modifies the determiner "the" and provides additional information about the noun phrase "the little children.")

4. "Some of the books on the shelf are mine." (The pre-determiner "some of" modifies the determiner "the" and provides additional information about the noun phrase "the books on the shelf.")

5. "Most of his friends are coming to the party." (The pre-determiner "most of" modifies the determiner "his" and provides additional information about the noun phrase "his friends.")

6. "Both my parents are teachers." (The pre-determiner "both" modifies the determiner "my" and provides additional information about the noun phrase "my parents.")

7. "Several of the students scored high marks in the exam." (The pre-determiner "several of" modifies the determiner "the" and provides additional information about the noun phrase "the students.")

8. "Many of the houses in this neighborhood are for sale." (The pre-determiner "many of" modifies the determiner "the" and provides additional information about the noun phrase "the houses in this neighborhood.")

9. "Most of the time, I prefer to stay at home." (The pre-determiner "most of" modifies the determiner "the" and provides additional information about the noun phrase "the time.")

10. "Both of my brothers are musicians." (The pre-determiner "both of" modifies the determiner "my" and provides additional information about the noun phrase "my brothers.")
