Answer 2

Complex sentence:

I am a student, I have a vision for tomorrow.

Explanation:

              A sentence could be termed a complex sentence if it has one independent clause and one dependent clause. It could be used when more information is to be communicated or when the main point of the sentence is to be modified.

But the meaning remains unchanged.

E.g., The food cooled down, I used the microwave to warm it.
