   No organism resists cancer better than sharks do, but some resist cancer as

   Why this is right

   The idea that some organisms resist cancer as well as sharks do contradicts the 2nd sentence, which said that "sharks have greater resistance to cancer than any other organism".

   Skill tested: Must be False · how this choice captures the argument's function is the move to repeat next time.

   Out of Scope: most susceptible19% picked this

   The organism most susceptible to cancer has a higher percentage of cartilage than some organisms that are

   We don't have any information on which organism is most susceptible to cancer, so there's no way we could contradict a statement about such an organism.

   The substance in shark cartilage that inhibits tumor growth is found

   We don't have any quantifier that would allow us to speak to the frequency with which the tumor-inhibiting substance in shark cartilage appears in other organisms. Maybe 49% of organisms have it, maybe 51% do. We don't know, so we can't contradict this claim. It might be tempting to think, "well, if most organisms had this same tumor-inhibiting substance, then why would sharks be so special in terms of greater resistance to cancer than any other organism?" It could just be that sharks have more of that substance / higher concentrations. Even though it can be found in most organisms, it can be found in highest abundance within sharks.

   In the past 20 years many terminal cancer patients have improved dramatically following many

   It doesn't go against anything we were told for many types of therapy to yield dramatic improvements. It would only contradict what we were told if some type of therapy yielded a more dramatic improvement than consuming shark cartilage did.

   Out of Scope: immune efficiency4% picked this

   Some organisms have immune systems more efficient than a shark’s

   We never talked about how efficient a shark's immune system is. Just because they are king when it comes to susceptibility to cancer doesn't mean that their immune system is maximally efficient. Since we didn't learn anything about immune efficiency, we can't contradict this claim.
