Sea Turtles

Answer and linking clues

Correct order: D, A, B, C

1. D. The bony shell of a sea turtle can actually sense when something touches it.
2. A. A series of thin nerves run along the shell and detect pressure changes associated with touch.
3. B. The nerves do not contain pain receptors, so scientists do not think sea turtles feel pain when touched on the shell, but these thin nerves could transmit information to other parts of the sea turtle’s body.
4. C. In addition, researchers and scuba divers have observed sea turtles respond to the stimulation of being touched on the skin of their head and their flippers.

Why this order

• D comes first: it introduces the topic and needs no sentence before it.
• A follows D: it picks up “shell” from D.
• B follows A: it opens with “The nerves”, which points back to something already mentioned; it picks up “nerves”, “shell” from A.
• C follows B: it picks up “turtles”, “touched” from B.
