Read the passage and choose the correct answer to each of the questions.

¹ The Pacific Northwest tree octopus is only found in the forests of Washington State, on the eastern side of the Olympic Mountains, in the United States. These creatures reach an average size of between 30 and 35 centimetres and live for around four years. They are unusual in that they live both in water and on land, a fact made possible by the very high amounts of rainfall in this part of the United States.

² Possessing the largest brain of any octopus, the tree octopus explores its surroundings by touch and sight. Some scientists believe that the way it has adapted to life in the forest mirrors the way early life forms adapted to life away from the water. Although they are not social animals like humans, they can still show emotions by changing their skin colour: red indicates anger and white, fear. Normally, though, they are a green-brown colour that matches their surroundings.

³ Every spring, tree octopuses leave their homes and travel to the coast to breed. Males soon return to the forest, while females lay their eggs underwater. The young then spend their first month or so floating near the shore before moving out of the water and beginning their adult lives in the forest.
