Questions & Answers about Haar antwoord was identiek, maar zij had een andere reden dan ik.
Why do we use dan instead of als in this sentence?
Because we are expressing a difference. The rule is to use dan after comparative forms and words expressing difference, like ander or andere (a different). If you were expressing similarity (the same reason as), you would use als: dezelfde reden als.
Why is there an -e at the end of andere?
Ander acts like a regular adjective. Because reden is a de-word, the adjective gets an -e ending, even after the indefinite article een. If it were a het-word, like het antwoord, it would just be een ander antwoord.
English speakers often say 'than me'. Why is it dan ik here instead of dan mij?
You are comparing subjects. The sentence essentially means 'she had a different reason than I [had]'. Since zij is the subject of the first part, the pronoun you are comparing it to must also be a subject pronoun (ik).
