Hello there!
Your question asks which is a fast and reliable source for emergency supplies that are needed overseas.
B). Airfreight
The reason why answer choice "B). Airfreight" is the correct answer because this is the distribution system that is the quickest to get things overseas.
When you think about going overseas, what do you use? A plane. When you think about going somewhere international, what do you use? A plane. That is the same concept when you're sending things overseas, you would use some sort of air craft to get it overseas.
An airfreight is a really big air craft that can transport tons and tons of supplies, items, etc. An airfreight can go over the ocean and to its destination very quickly. The plane can go hundreds and hundreds of miles per hour for a long period of time. This is why people would use an air freight to deliver emergency supplies overseas.
Why the other answer choices are incorrect:
Answer choice "A). railroads" is incorrect because railroads can't go overseas. Have you seen railroads built over the ocean? Absolutely not. Therefore, trains can't go over the ocean because there's no railroads built over the ocean. This is why this answer choice is incorrect.
Answer choice "C). trucking" is incorrect because there is no road over the ocean, therefore the travel path would be cut off for the trucks. In order for the trucks to go overseas, they would need to be transported on a boat, in which would take a long time. This is why this answer choice is incorrect.
Answer choice "D). pipelines" is incorrect because pipelines don't extend to places that are overseas, and pipelines would not be a safe thing to use to get emergency equipment distributed. This is why this answer choice is incorrect.
Answer choice "E). waterways" is incorrect because water ways are just water, large bodies of water to be exact. There is no transportation system in waterways, therefore making this answer choice incorrect.
I hope this helps!Best regards, MasterInvestor
