A
There are many shops in Singapore where customers still bargain, although prices are clearly shown on the goods. There is nothing out of the ordinary in haggling; some shopkeepers expect you to and will be surprised if you accept their prices immediately. We know that the prices in some stores are a bit higher than those in Change Alley, but we also realize that to keep a store like Robinson’s is by no means cheap. Besides, in such places we shop in air-conditioned (空调) com-fort. For all these, we pay a little extra.
It is not always true to say that things in Change Alley cost less. I once bought a Czechoslo-vakian glass butter-dish from Robinson’s for a little under two dollars. I then went on to Change Al-ley and just by chance saw an article of the same shape, design and size, in one of the shops.

[单项选择]The collapse of the Earth’s magnetic field—which guards the planet and guides many of its creatures—appears to have started seriously about 150 years ago, the New York Times reported last week.
The field’s strength has decreased by 10 or 15 per cent so far and this has increased the debate over whether it signals a reversal of the planet’s lines of magnetic force.
During a reversal, the main field weakens, almost vanishes, and reappears with opposite polarity. The transition would take thousands of years. Once completed, compass needles that had pointed north would point south. A reversal could cause problems for both man and animals. Astronauts and satellites would have difficulties. Birds, fish and animals that rely on the magnetic field for navigation would find migration confusing. But experts said the effects would not be a big disaster, despite claims of doom and vague evidence of links between past field reversals and species extinctions.
Although a total transiti
A. begun to change in the opposite direction
B. been weakening in strength for a long time
C. caused the changes on the polarities
D. misguided many a man and animal
