is this not a thesis statement ?
Various approaches to prevent steroids in sports have not been successful because athletes are now using hard-to-detect growth hormones to enhance performance.
I mean I don't see how this isnt a argument
Can you see that it is merely a statement of fact? For an argument you need to "pick a fight." Now if you said "Clear X should NOT be the case......" someone will debate the other side = "Wrong, it SHOULD because......"
But I thought thesis statements cannot have "should"
you need to change your approach. For instance, Steroid use by athletes should not be grounds for denying competitive opportunities. Then you can use various arguments to support that.
Meaning .. ?
What is it exactly that you don't understand.
These two sites will explain what a thesis statement should do and how it is constructed.
