Questions 7-8
    In a swampy area of South America, the highly poisonous coral snake and a much less venomous kind of snake both bear red, black, and white bands. Only 100 miles away, on drier ground, the local type of coral snake lacks the red bands. And there, the less poisonous species of snake lacks the red bands, too. The explanation is that, in both habitats, close imitation of the coral snake affords the less poisonous species a measure of protection it would not otherwise have.
    7. Which of the following is most likely to be a major assumption underlying the explanation in the passage above?
    (A) Coral snakes claim individual territories for themselves, which they defend against other snakes.
    (B) Red coloration is effective camouflage primarily in dry habitats, where natural reds are much more common than elsewhere.
    (C) The sight of a coral snake has a strange paralyzing effect on certain of its prey animals.
    (D) Predators whose diets include snakes tend to avoid those most poisonous and thus most dangerous to them.
    (E) Snakes of different species will peacefully coexist only if they do not compete for the same foods.
    8. Which of the following can be logically inferred from the passage above?
    (A) All varieties of coral snakes have red, black, and white bands.
    (B) The differentiation among coral snakes into those with and those without red bands predates the corresponding differentiation among the less poisonous species of snake mentioned.
    (C) The less poisonous snake species mentioned produces the same venom that the coral snake does, but less of it.
    (D) Coral snakes from different habitats also have different types of venom.
    (E) The protection that the less poisonous species of snake mentioned derives from the coral snake means that the less poisonous species of snake must be useful to the coral snake in some way.
