What is the lo for? I thought the sentence was saying "she made it the same as I did."
Hardly. Many a professional writer has begun using "as" similarly to the word "like". Approve of it or not, lexicon changes and evolves over time; it has entered common usage to the point that a majority of professionals in academia wouldn't even bat an eyelash at phrase "same as me."
this sentence is completely grammatically incorrect. It should read 'She did the same as I did' usually abbreviated by the omission of the final 'did'. As given the answer equates to : 'She did the same as me did' which would pass no English language exam. The sentence, as constructed, is lazily wrong.
