Answer:
Complex sentence
Step-by-step explanation:
A sentence can be defined as a group of words that comprises of both a subject and predicate used to convey a logical information. Sentences are classified into three (3) main categories and these includes;
I. Simple sentence.
II. Compound sentence.
III. Complex sentence.
A complex sentence comprises both an independent clause and a dependent clause. Therefore, a complex sentence has at least one dependent (subordinate) clause.
A dependent clause refers to a type of clause that is inserted into another clause to make meaning or express a complete thought.
An independent clause can be defined as a clause that expresses a complete thought while standing alone as a simple sentence and comprises of at least a subject and a verb (predicate).
The dependent clause in the sentence "If somebody wishes to volunteer,
we will begin." is "if somebody wishes to volunteer" while "we will begin" is an independent clause and expresses a complete a thought while standing alone.
Hence, the above sentence is an example of a complex sentence.
