How can I fix this sentence?

some of the questions I asked him are “Tell me reasons why did you end up staying at the hospital?” and “Tell me more about the pain in your right leg?”

All you need to do with that sentence is to capitalize the first letter. The rest is grammatically fine.

The sentence is very wordy, though, and reads very awkwardly, so my suggestion is that you get rid of the direct questions and the extraneous words. Here's a possibility:

I asked him to tell me why he stayed at the hospital and more about the pain in his right leg.

Or ...

I asked him to tell me more about the pain in his right leg and why he stayed at the hospital.

what do i already know about contemporary realistic short stories?

can you answer my question now

at forzan, i don't get what you are trying to ask me

To fix this sentence, you need to correct the use of question marks and the verb tense consistency. Here's the corrected version:

"Some of the questions I asked him are 'Tell me reasons why you ended up staying at the hospital?' and 'Tell me more about the pain in your right leg?'"

To fix the sentence, follow these steps:
1. Remove the unnecessary third question mark after "hospital" and change it to single quotation marks as it represents dialogue.
2. Change the verb tense from "did you" to "you ended" to maintain consistency throughout the sentence.
