The following sentence is taken from the interview with Mansour Al Marri; however the words have been mixed up.
Rearrange the words to create a grammatically correct
sentence.
we do something / we won't have anything / unless / to protect what
we have, / to give our children

We won't have anything to give our children unless we do something to protect what we have.

Explanation:

Every sentence must contain a subject and predicate and express a complete thought. A grammatically correct sentence is a sentence that follows all rules of grammar.

Here, we have mixed up words that need to be properly arranged in order to make sense (i.e. to express a complete thought) and follow said rules. The given sentence is made up of two clauses - one independent and one dependent clause, which makes it a complex sentence. Both of these clauses contain a subject and predicate, which must agree in number.

These are the things that we need to keep in mind when trying to put a sentence together.
