Is my sentence grammatically correct? I'm not sure if it's possible to use the past simple with the present perfect in the sentence below.
To understand how this came about / has come about, we need to look at the different political and social events that have influenced the development of English.
Please, correct all my mistakes. I should know English perfectly and if you show me my mistakes I will achieve my dream a little bit faster. A lot of thanks.
