Paragraph: (Science-textbook/science-g5-83.txt)
Sent 1: Earths magnetic field helps protect Earth and its organisms.
Sent 2: It protects us from harmful particles given off by the sun.
Sent 3: Most of the particles are attracted to the north and south magnetic poles.
Sent 4: This is where Earths magnetic field is strongest.
Sent 5: This is also where relatively few organisms live.
Sent 6: Another benefit of Earths magnetic field is its use for navigation.
Sent 7: People use compasses to detect Earths magnetic north pole.
Sent 8: Knowing this helps them tell direction.
Sent 9: Many animals have natural 'compasses' that work just as well.
Sent 10: Birds like the garden warbler in Figure 1.36 use Earths magnetic field.
Sent 11: They use it to guide their annual migrations.
Sent 12: Recent research suggests that warblers and other migrating birds have structures in their eyes.
Sent 13: These structures let them see Earths magnetic field as a visual pattern.

Question: What is unique about the north and south magnetic poles? (false/15)

It holds the gravitational pull of the planet
Most particles are attracted to them. This is where Earths magnetic field is strongest. This is also where relatively few organisms live
Earths UV field is strongest
Earths center of gravity field is strongest
Where Earths magnetic field is strongest
It is the coldest
Annual migrations
Earths magnetic field is weakest
It is the warmest

Question: Is Earths magnetic field strongest in the East and West, or the North and South? (true/16)

North and Soutn
East and West
The North and South

Question: What species in this passage is mentioned to use use the Earths magnetic fields to guide its annual migration? (false/17)
