#2 is wrong. #3 & #4 are passive forms of #1. #1 is best. :)
6 and 8 are wrong. #7 is a passive way of saying the same as #5.
In the sentences you provided:
1. "He let me go there." - This is an active sentence where "he" is the subject, "let" is the verb, and "me" is the object.
2. "I was let to go there by him." - This sentence is not a correct passive construction. The correct passive form would be: "I was let go there by him."
3. "I was allowed to go there by him." - This sentence is a correct passive construction of sentence #1. "I" is the subject, "was allowed" is the passive verb phrase, and "go there" is the complement.
4. "I was permitted to go there by him." - This sentence is also a correct passive construction of sentence #1. "I" is the subject, "was permitted" is the passive verb phrase, and "go there" is the complement.
Regarding the second set of sentences:
5. "He had me eat brown rice." - This is an active sentence where "he" is the subject, "had" is the verb, and "me eat brown rice" is the object.
6. "I was had to eat brown rice by him." - This sentence is not a correct passive construction. A correct passive form would be: "I was made to eat brown rice by him" or "I was forced to eat brown rice by him."
7. "I was asked to eat brown rice by him." - This sentence is a correct passive construction of sentence #5. "I" is the subject, "was asked" is the passive verb phrase, and "eat brown rice" is the complement.
8. "I was got to eat brown rice by him." - This sentence is not a correct passive construction. A correct passive form would be: "I was allowed to eat brown rice by him."
To summarize, sentence #2 and sentence #6 are incorrect passive constructions. The correct passive forms for sentence #1 would be sentence #3 and sentence #4. The correct passive forms for sentence #5 would be sentence #7. Sentence #8 is not a correct passive construction.
