  1. in the middle · B sits between.
  2. 10 cm · 10 is smallest.
  3. A, B, C · Pencil A is shortest, then B, then C is longest.
  4. True · This is always true, even without comparing the rope and pencil directly.
  5. The yardstick is longer than the crayon · If the yardstick beats the ruler, and the ruler beats the crayon, the yardstick beats the crayon too.
  6. 14 cm, 11 cm, 9 cm · Large to small is 14, 11, 9.
  7. 6 · 20 minus 14 is 6 cm.
  8. True · Order passes along.
  9. No, it should be C, B, A · Since A beats B and B beats C, A is the longest, so shortest to longest is C, B, A.
  10. Pencil, Shoe, Book · The pencil loses to the shoe, and the shoe loses to the book, so the pencil is shortest and the book is longest.
