Final answer:
To remove the first sentence from a string, write a function that finds the end index of the first sentence and returns the string without that portion.
Step-by-step explanation:
To write a function that removes the first sentence from a string, you can use string manipulation techniques in a programming language like Python. Here's an example:
def remove_first_sentence(string):
# Find the end index of the first sentence
end_index = string.index('.') + 1
# Return the string without the first sentence
return string[end_index:]
# Example usage
string = 'This is the first sentence. This is the second sentence.'
new_string = remove_first_sentence(string)
print(new_string) # Output: ' This is the second sentence.'
