What the heck is amnesia? I´m sure I used to know it, but somehow I forgot ...

Level 84

loss of memory

Loss of what?

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?

Level 69

Apparently so.

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

Level 78

Dec 6, 2017

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

Mar 19, 2018

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

Level 43

Mar 19, 2018

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

Level 73

Mar 19, 2018

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.)

Level 79

For some reason I thought the name of the largest island was "Papua" instead of "New Guinea"...

Level 53

Mar 19, 2018

Can you please accept 'Papua' for New Guinea as well :)

Level 70

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.

Level 91

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.

Level 58

Mar 19, 2018

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?

Level 67

Mar 19, 2018

The largest island is Borneo. New Guinea is half of that island.

+13

Level 69

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.

Level 74

Jul 29, 2018

New Guinea is bigger than Borneo

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

Interesting...

My bad. You're right. Thanks

Level 65

I wrote Aleut and Aleuts instead of Aleutian Islands

Level 39

Jun 11, 2022

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.

Doesn’t Nauru have a larger coastline than Tuvalu? Tuvalu is about 15 miles and Nauru is about 19 miles. I believe Tuvalu is the smallest country that touches the Pacific?

I think Papua New Guinea should work for the question as well. That’s really knit picky. If you ask the average person, they will call it Papua New Guinea. I mean it’s really the Gulf of Mexico! Calling it the Gulf of America just sounds silly. I’m kind of surprised he didn’t call it the Gulf of Trump?

What is it with American quizzers always trying to claim the highest mountain with "if measured from the sea"?

Well Mount Chimborazo is the highest if measured from the centre of the Earth.

And the UK has the most Olympic medals per capita by nearly twice as many as the USA with the Bahamas on 7x as many.
