yes. ;)

To determine whether the sentence is compound, complex, or compound-complex, we need to analyze its structure.

The given sentence is: "Volunteer helped clear roads so that supplies could get to villages that needed them."

To determine whether a sentence is complex, we look for the presence of an independent clause and at least one dependent clause. In this sentence, we can identify an independent clause: "Volunteer helped clear roads."

There is also a dependent clause: "so that supplies could get to villages that needed them." This clause starts with a subordinating conjunction ("so") and includes a subject ("supplies") and a verb ("could get").

Based on this analysis, we can conclude that the sentence is indeed complex, as it contains an independent clause and a dependent clause.
