Exam Prep Answers

  1. Choice A is incorrect. Rule 1 states that Hal plays after Ralph on the roster. If we go through the list, we see that in answer choice A, Hal plays way before Ralph, so this roster is invalid.

  2. Choice B is incorrect. Rule 3 states that Corwin and Seth can't be next to each other in the roster. However, we can see that answer choice B has them batting fourth and fifth, which violates this rule.

    Choice C is incorrect. Rule 5 states that Peter must be first or second in the rotation. Going through the two remaining answer choices, we see that he's fourth in answer choice C, which makes this choice an invalid roster.

    Choice E is incorrect. Rule 2 states that of the set Dorian, Kamal, Ralph, exactly two of those three people must be on the team. As we go through the remaining choices, we see that answer choice E only has Ralph and not Dorian or Kamal.

    We're left with one answer choice, D, which is the correct answer.

  3. Choice A is incorrect. Anne can be anywhere from either the first, second, or third puppy to arrive at the vet's office, so this choice might be true, and therefore is incorrect.

  4. Choice C is incorrect. Cassie can be the third, fourth, or fifth puppy to arrive at the vet's office, so this answer might be true and therefore is incorrect.

    Choice D is incorrect. Daisy can be the sixth, seventh, or eighth puppy to arrive at the vet's office, so this answer might be true and therefore is incorrect.

    Choice E is incorrect. Fancy can be the fifth, sixth, or seventh puppy to arrive at the vet's office, so this answer might be true and therefore is incorrect.

    By process of elimination, Choice B is correct. Boris can be either the second, third, or fourth puppy to arrive at the vet's office. Since he cannot be the fifth to arrive, this choice cannot be true and therefore is the correct answer.
