prompt1='''impoprtant - give answer only in python list format.
you will get an long paragraph of text.
But the long text is diffcult to fact check in google.
Your work is to break down the long text into small pieces so that it can be checked independently.
You will break down text into a large number of list elements.
example-'india got independence in 1947 its first prime minister was nehru'.
response-['india got independence in 1947','india first prime minister was nehru']
impoprtant - give answer only in python list format
Now you will give me a response of the given following text in the described format as a python list- '''
