Make sure you don’t have tally marks on your arm... oh, wait, I have some on mine, but I can’t seem to remember how they got there or why I’m writing this. ;)

Is that what happens when you have amnesia and deja vu at the same time?

way too much time! It is not an easy quiz, moderately tough, but 8 minutes is way too generous. good variety of questions.

agreed. I got bored trying to think of the last two and I still had like 4 minutes to go.

It was the right amount for me. I finally remembered the third "nesia" with 45 seconds left. Great quiz for me.

Please accept just California

that is a state in the US, not a part of Mexico.

Baja was accepted for me. Americans often shorten it, but not to California - too confusing, as Paco said, with the US state. (Perhaps it is different in Mexico.)

For some reason I thought the name of the largest island was "Papua" instead of "New Guinea"...
+2
Level 53
Mar 19, 2018
Can you please accept 'Papua' for New Guinea as well :)
+6
Level 67
Mar 19, 2018
Papua itself is a province of Indonesia on the west of the island and the cultural group. New Guinea is the name of the island but could well have been called Papua in the past.
+1
Level 86
Mar 19, 2018
And, of course, Papua is used in the name of the other half of the island that isn't the Indonesian provinces of Papua and West Papua.

I'd suggest it's like Munchen or Den Haag - it's not the English name, but it is something the island is called.

The name of the island is New Guinea. Papua is simply incorrect and is not used in English to refer to the whole island, officially or otherwise. Why do you want an incorrect answer to be acceptable?

The largest island is Borneo. New Guinea is half of that island.
+12
Level 68
Mar 20, 2018
Nope. Borneo is divided between Malaysia, Indonesia, and the small country of Brunei. New Guinea is the name of one of the largest islands in the world, which itself is split between Indonesia and Papua New Guinea.

So you're saying, 786,000 km² = 0.5 * 752,000 km² ?

Please accept Rapa Nui for Easter island, soon will be the only official name of this island!

Thanks :)

Well, it says that the inhabitants are the Rapa Nui, so that would be a little weird to give it away in the clue, and plus it is commonly known as Easter Island.

8 minutes? That is way too much, I was able to do it in two while eating (doing it one handed)!

The island of Australia is much larger than New Guinea. I guess it is not completely in the Pacific?

Can't you accept antimeridian? That's what it is called everywhere. Even wikipedia doesn't even call it "day changing" or whatever.

Level 43
Jul 30, 2021
Yes, I agree. International Date Line should not be accepted here because the opposite of a straight line should be a straight line, not a line that meanders around Russia, the US, and several Pacific island countries.

A bit generous with the time. Right now, someone with a WPM of 5 would be able to finish this quiz if they knew all the answers. Maybe cut the time in half?

Please accept anti meridian. Antimeridian is the name for 180° of longitude, and in fact the international date line doesn't even follow 180° because it squiggles around Kiribati, Samoa and Tonga.

If China and Southeast Asia are included in the Pacific Theater, there will be countless tragic battles. For example, in the Battle of Songhu, during the same three-month battle, some data stated that the Japanese army suffered more than 90,000 casualties and the Chinese army suffered more than 250,000 casualties. In the battle to defend Wuhan, the Chinese army suffered as many as 650,000 casualties.
