Answer:
The complex sentence is:
Although I am tired, I will finish my homework.
Step-by-step explanation:
A complex sentence is formed by joining an independent clause and a dependent one. A dependent clause needs the independent one to give it context, so that it makes sense. It does not express a complete thought on its own.
In the sentence "Although I am tired, I will finish my homework," there are two clauses:
1. Although I am tired
2. I will finish my homework
In the first clause, we have a subordinating conjunction, "although". Subordinating conjunctions are used to introduce dependent clauses with a contrasting idea to the main clause.
The main clause, or independent clause, in this case, is the second one. It presents a complete idea on its own.
Therefore, in "Although I am tired, I will finish my homework," we have a dependent clause and an independent one, which forms a complex sentence.
