Question

Scientists from the Geological Survey of Canada go hunting every few years. They dress in thick winter coats and warm gloves, tuck compasses in their pockets, and jump on airplanes that fly out over Canada's arctic region. They look down on a vast and empty landscape with only a few tiny islands and shiny sea ice. What they hunt is always moving and cannot be seen with their eyes. These scientists are hunters of Earth's magnetic north pole.
In December 2003, Earth's north magnetic pole was located 600 kilometers from the northern Canadian town of Resolute Bay. But it has not always been

Answer 1

so dangerous. Ross's ship had been stuck in the arctic ice for four years! In 1904 when Roald Amundsen looked again and found the magnetic north pole, it had moved 50 kilometers.
Sometimes, the Earth's magnetic north pole even trades places with the magnetic south pole. This strange event has been recorded in the magnetism of ancient rocks and happens about every 300,000 years. Geologists can't predict when the poles will swap places again.
Scientists have been recording the movement of the magnetic north pole across Canada since James Ross first found it. It was moving at an average speed of 10 kilometers a year until the end of the 1900's. Then the speed increased to 40 kilometers per year. One day in the near future, the scientists from the Geological Survey of Canada will have to do their hunting in Siberia instead of Canada.

Answer 2

5.
Which statement summarizes the main idea of the selection?

Scientists hunting in remote Canadian areas should always wear coats and gloves and carry compasses.
Dangerous Arctic weather conditions make it hard for scientists to find Earth's magnetic north pole.
Earth's magnetic north pole has been moving since scientists first began keeping records of it.
Explorers gave up searching for the magnetic north pole because of dangerous Canadian weather.

Answer 5

Do you have a guess of which one it is?

Answer 6

b

Answer 7

No, it isn't B. They only talk about the weather briefly. So that cancels out A too.
