Which element is third to left of sixth element from the right end in step 4?

  • A.18
  • B.11
  • C.import
  • D.dice
  • E.house

Answer: B

Correct answer: 11

The machine pairs each vowel-initial word with a prime and each consonant-initial word with a composite, taking the words alphabetically and the numbers in ascending order, and places one pair per step alternately at the front and the back. For this input the pairs are energy 3, import 11, upper 23, dice 8, house 18, queen 27, and step 4 reads energy 3 import 11 dice 23 8 upper house 18 queen 27. Counting six from the right gives “8” at the seventh place from the left, and three to its left is the fourth element, 11.
