care of their young. It is a very dangerous world for baby birds. So having two
parents taking care of the babies means they are more likely to survive. (3)

difficult to get to. When the Spanish came to colonize Peru in the sixteenth century,

been very tall, narrow, circular towers with a revolving light on the top. In the past,

people needed to live in the lighthouses to turn the lights on and to check that

everything was working correctly. Now everything is automated it is not necessary

for people to live in lighthouses anymore. (3)
