Answer:
Well, technically, there are two of each as shown below.
Explanation:
he + ran
boy + lost
If you had to choose only ONE pair as the answer, then go with "boy + lost" because they are contained in the main (independent) clause of the entire sentence. The entire sentence is actually a complex sentence because it is composed of a dependent (subordinating) clause + an independent (main) clause.
Does that make sense?
A clause that can not stand alone is a dependent clause, also known as a subordinate clause. It is reliant on an independent clause.
Hope this helps, let me know if you need more help or further explanation! :)
