The present North and South pole on the geographical region above Earth crust is opposite beneath the same as North to be South and South to be North pole. Before 65 million years, Earth polarity was same beneath as currently above Earth's crust. It reversed and the Earth faced the mass extinction.
The magnetic field of the Earth was opposite to what it is found today, 65 million years ago, which is considered to be the time for mass extinction.

Answer:
B. decrease in imports
Explanation:
The formula to calculate GDP is: GDP = C + G + I + X - M
In that, C stands for consumer spending, G stands for government spending, I stands for investment, X stands for exports and M stands for imports.
As indicated in the formula, consumer spending, government spending, investment and exports are directly proportional with GDP. So that when there is a decrease in these factors it would result in a decrease in GDP as well.
Oppositely, import is inversely proportional with GDP, thus a decrease in import will lead to the increase in GDP, causing the economic growth.
