So I didn't think long enough about the gold rush question and I didn't think there were quite that many Hispanic people in California. Those were the two I missed. Having visited the town where Reagan was born in Illinois probably helped with that one.
For what country would you hit I was like “ummmmmmm China?” Because I really thought it was China. Went with The Philippines. Ouch. Seriously though, why is India an option when it wouldn’t even be possible to not hit Thailand or Malaysia or maybe even Indonesia?
A teacher once told me that when creating a multiple choice test she always had one completely outrageous answer that anyone should be able to eliminate unless they just didn't care, one that would be easily eliminated if one even partially studied, and two answers that seemed as though they could both be correct but only a student who truly knew the material would choose the better answer. Maybe India is QM's outrageous answer.
It turns out that the earth is round. So if you sailed directly west from San Francisco, and never turned, you would end up way south of Japan. Similarly, if you want to fly to Japan, you have to fly to the northwest. I guess the correct way to phrase the question would be, "What country is due west of San Francisco?"
I think you're a little confused about the implications of the fact that the earth is round. There's nothing stopping you from sailing due west along a line of latitude from San Francisco; and you will end up arriving at Japan (in your fantasy sailing vessel that ignores weather, fuel, etc.)
You do not "have" to fly to the northwest to get to Japan--it's just the shortest path. It's called a great circle route and your commercial flight will surely fly a course pretty close to it, so as not to waste time and fuel. (Real flight paths deviate for all kinds of political, safety, etc. reasons from these ideal great circle routes, of course).
In neither case would you need to "turn". Both ideal paths will be straight with respect to the track on the surface of the earth. They both will seem curved or straight on a flat map, depending on the type and center of the projection.
No, Ing is actually correct, if you depart due west from San Francisco you would actually end up in Papua New Guinea, (if you don't hit one of the islands in Marshall Islands or FS Micronesia first). if you have a flat map and draw a straight line headed west you will reach Japan, but in real life this would require you to change direction as you go. This is better displayed if you get close to the poles. If you go straight west when you are very close to a pole and stay at the same latitude, you will eventually go "all the way around the world", but in reality you walked in a relatively small circle. The only path where you don't have to slightly turn as you go is actually the great circle route.
Interesting--I do see what you mean. What I said isn't right.
The question, though, is correct--it never mentions "not turning", for example. But I see that you're right, that following a "directly west" course from San Francisco requires a "turning" course so that you are always on the same line of latitude as you started.
Bold take, while the state was Spanish then Mexican land, an heritage found through local Californio population who stayed and Spanish toponimy across the state, required and welcomed workforce throughout its history, ...
