Answer: a) Imports > Exports = Trade Deficit
Explanation:
When something is said to be in deficit, it means that more money is being spent than is being received. This is why this situation is called a trade deficit, because imports represent spending and exports represent gains and when there is more spending than gains, there is a trade deficit.
When however, there is more exports than imports, you have what is called a trade surplus. Not a lot of countries can manage this.
The correct answer is option B.
Edmond Halley correctly predicted the return of the eponymous comet Halley after he realized several sightings of a comet were in fact the same comet.
By correctly understanding Sir Isaac Newton's law of gravity and also his ideas in mathematics, Halley was able to correctly predict that the comet that now bears his name would return periodically. He did this by discovering Halley's orbit in 1716 and thus being able to predict the year of its return.
This would be an answer
