Here's the thing volleyball is my life I play it everyday after schol with some friends and other people you can't just ask people to help you make a poem for it, you should just feel it and come up with on your own. If you love this sport as much as I do it will take less than 5 minutes.
The correct answer would be B, since complex sentences have 1 independent variable and one dependent variable.
The dependent variable would be: Everytime he hears a siren
Why? Because it is not a complete thought.
The independent variable would be: My dog howls loudly.
Why? This statement is a complete thought.
A would be a compound sentence
C would be a simple sentence
D would be compound complex.
Hope I could help!
