  1. Beatit, in the absence of D, will C be a correct choice?
  2. C provides the pillar (a valid assumption) without which the premise and the conclusion will not hold.
  3. E for me. Assume "they" refers to "eating habbits"; Is it possible for "eating habbits" to be "...as thin as possible ?"
  4. a is the sum of x consecutive positive integers. b is the sum of y consecutive positive integers. For which of the following values of x and y is it impossible that a = b? (A) x = 2; y = 6 (B) x = 3; y = 6 © x = 7; y = 9 (D) x = 10; y = 4 (E) x = 10; y = 7
  5. If x, y, and z are positive integers such that x (1) x and y are prime numbers, whose sum is a factor of 57 (2) z is a factor of 57
  6. D, ofcourse, is the valid assumption.
  7. A: ...less Co2 and far fewer of the other gasses... Co2 (non-countable) => less No of gasses (countable) => far fewer
  8. What is the value of y + x^3 + x? (1) y = x (x - 3) (x + 3) (2) y = -5x
  9. Arjmen, beautifull explanation. Thx.
