Change the question in parentheses to a noun clause:
1 - (what are you doing?) Sara wants to know
2 - (where do you live?) Please tell me
3 - (whose book is this?) I do know
4 - (why did they leave early?) Do you know
5 - (who is the president of France?) I am not sure
Noun clauses are dependent clauses, meaning that they are sentence fragments. They can function as predicate nominatives, objects of prepositions, subjects, appositives, direct or indirect objects. They function as nouns within the sentence.
1. Whatever it is you are doing, Sara wants to know.
2. Please tell me where it is you're living.
3. I know whose book this is.
4. Do you know what their reasons were for leaving early?
5. Whomever the president of France is, I don't know him or her.
Noun clauses commonly begin with these words: how, that, what, whatever, when, where, whether, which, whichever, who, whoever, whom, whomever, and why.
Noun clauses can be used as adverbial nouns. This is when a noun acts like an adverb modifying a verb, an adjective, or an adverb. Example:
She is sure that she doesn't want to see him again. (The dependent clause modifies the predicate adjective sure.)
Essentially, you are changing the question into a statement (with the exception of example number four). Instead of asking the each example in the form of a question, one can manipulate the structure of the sentence to form a statement. Also, in the question, the sentences can be separated into two sentences. For example, "What are you doing? Sara wants to know." By combining the sentences, one can vary the sentence structure and create statements instead of questions.
Here are the sentences using a noun clause.
1. Sara wants to know what you are doing.
2. Please tell me where you live.
3. I do know whose book this is.
4. Do you know why did they leave early?
5. I am not sure who is the president of France.
