Reason​

Answer 1

here's ur answer buddy

Although she was tired, she went to work.

OR

She was tired but she went to work.

why u may ask

here's ur answer to that

the word itself implies that she went to work being tired. it makes a meaning that she forced herself to go to work even being tired.

so only one of the the two words will work or the meaning of the sentence will change to the original meaning.
