What is sharpness? Is this a image quality factor question (image sharpness), or depth of sharpness, a composition factor question (how many objects in the scene got sharpped)? I quess this question is more about image quality. Can aperture control image quality? But, how you answer the question: one way to control sharpness in a picture is with aperture, T or F?

It's been quite some time since I played with a 35mm SLR camera. "Sharpness" has everything to do with focal point. Think of it this way, using a zoom lens, you focus on a given object, everything in front of and behind appears out of focus. But your object is sharp. Got that? Your aperture is controlled by your F-Stop. It's the size of your "Iris." The smaller it is, the less light gets through. It alone can change how sharp your object appears. But generally, F-Stop is combined with shutter speed and that speed will ultimately determine the amount of light passing through your lens to the film. Again, the faster the shutter speed, the less light that is allowed to get in. The slower the speed, the more light. So, by combining those two factors with your ability to focus on an object... Sharpness.

True. I am not familiar with digital photography yet. The smaller the aperture on a SLR film camera the clearer (larger depth of field),however the amount of light needed is greater. The longer the aperture is open the more motion of the camera is detected which can burr the photo as well. I you have a tripod for a SLR then use, if your camera is an older model you may want to use a trip for the shutter release. These will help control sharpness in your photos. Practice is the only way to find out.

The main thing that controls "sharpness" in a photography is the focusing. The aperture controls what will be in focus in-front and behind what the principle object or main subject of your photography will be. If you want a greater depth of field then you need to use a smaller aperture (larger f-stop number) If you want less depth of field then you need to use a larger aperture (smaller f-stop number)
If you want maximum sharpness then you need to use the hyper-focal length method which is stopping down to your maximum aperture and manually changing infinity on the lens to match up with the aperture number on the lens. Some of the newer lenses can not do this. Also, after doing this, when you look through the lens it should be not in focus.
Also some cameras have a stop down switch so you can tell what will be in focus and what will not be in focus.

True-ish.
The smaller the aperture the greater the depth of Field. That is a larger range that will be sharp. In a shallow depth of Field only the things at exactly the distance you are focused at will be in focus.
