“Barack Obama is the 40th President of the United States.”
The sentence “Barack Obama is the 40th President of the United States” is an affirmative sentence.
To ask if Barack Obama is the 40th President of the United States we need to form an interrogative sentence.
For example:
- Is Barack Obama the 40th President of the United States?
Do you see how the word order changes in when forming an interrogative sentence? The verb (is) is placed before the subject (Barack Obama).
