It is necessary to label a football helmet under Sports Gear.

It is sufficient to have a football helmet in the sports gear category.
It is NOT sufficient to have a chefs hat in the sports gear category, because it doesn't meet the conditions of being in the sports category. Cooking is not a sport! (yet... lol)
Being on earth is sufficient for being in the universe, but not necessary. Being in the universe is neccessary for being on earth but not sufficent. You can be on Mars or Pluto and still be part of the universe.
I feel like this is a good question to ask yourself that is substitutable. "If I'm a cat do I have to be a mammal?" Yes, being a mammal is necessary for being a cat, therefore mammal is the necessary condition in this relationship. This question is substitutable in that you can just ask yourself "If I'm x do I have to be Y?" If the answer is yes then Y is more than likely the necessary condition. Sorry if this has been mentioned but this helped me be able to understand the point enough to simply explain to other people. Also the question you ask yourself should be phrased in relation to the material in the question. I could say "if I'm in Syracuse then I'm in Indiana....I'm in Syracuse therefore I'm in Indiana" and it could be logical true but factually wrong and asking yourself "If I'm in Syracuse do I have to be in Indiana" would make you second guess but if that's what the stimulus says, I hope not, but you would go along with it. Hopefully what I just said is correct too.
Also from the way I'm understanding it (someone please correct me if I'm wrong), sufficiency is usually a guarantor but not necessary because it's a specific subset of a category? Is a good rule of thumb (when looking at these types of questions) to sniff out what the broader categories are to better relate sufficiency and necessity?
Preworkout is sufficient (guarantees) that it is a caffeinated drink.
Being a caffeinated drink is necessary (required) for it to be preworkout. But not the other way around. Saying something is a caffeinated drink isn't enough for you to infer that it's preworkout; it could be coffee, tea, Monster, etc.
