Answer:
Use a subordinating conjunction to connect it to an independent clause.
Explanation:
A <em>dependent clause </em>are phrases that answer <em>wh-</em> questions such as when something happened, where, and why as well as how and to what degree.
For example:
"When it is hot outside,..."
"When you are at their house,.."
"As you approach Publix,..."
<em>Subordinating Conjunctions</em> connect these phrases to independent clauses, or phrases that have complete a full thought.
Examples:
"When"
"Although"
"While"
"Whenever"
Once put together you get full sentences like:
"<em>When</em> it is cold outside, put on a jacket."
"Drive on 3rd street <em>till</em> you reach her home."
