Welcome to RQ #296. Sorry for the delay.

In each of the questions you will be asked to name the best 5 (largest,
longest, nearest) of some type of object. You do not have to give them
in any order; if any answer you give is one of the 5 asked for, you get
the point. No penalty for wrong answers, so guesses are encouraged.

This quiz will run until Monday, 09 July 2018 in the evening my time
(time zone -7 UTC).


1. What are the 5 largest countries? (by area, not population)

2. What are the 5 longest rivers in the world?

3. What are the 5 largest islands in the world? (not Australia)

4. What are the 5 largest planets in the solar system?

5. What are the 5 nearest star systems to the sun? (not brown dwarfs)

6. What are the 5 largest first level administrative subdivisions of the
various countries? (by area, not population)


Note: First level administrative subdivisions is a collective name for
subnational units (states, provinces, territories, semi-autonymous
regions, etc.) that are not part of a larger subnational unit.

For this question, rivers do not include those where a combined
river+tributary is longer than the nominal main river.

What if people give more than 5 answers on a question?

By what measure, in case it matters?

Sakha is one of the 89 constituent entities in the Russian Federation,
but I seem to recall that Putin introduced a division of seven
administrative units on top of these 89, and in that case five of
these are likely to be the answers. But I have no idea what the names
of these units are. (And even I am wrong about these ober-units, I would
expect that there are more answers in Russia, but I have no idea what
the names are, which I why I placing my bets in China.)

Then only the first five answers they give will be considered. I'd
thought about putting this in the original quiz, but it hasn't been a
problem in past quizzes, so I figured I didn't need to specify it.

As far as I can tell, those divisions are purely for the administrative
convenience of the central government. They have no governments
themselves, so I don't count them.

Good for me. :-)

If memory servers, they have governors which are appointed by Monsieur Putin
himself. Presumably, the governors have some people around them, but there
is no locally elected body. Then again, that was not required in the
original question.

In the US, various agencies of the federal government chop the country
up into a small number (usually 10 to 12) regions or districts for ease
of administration. The Forest Service, Environmental Protection Agency,
Bureau of Land Management, Geologic Survey, Coast Guard, and others all
do this. And these districts all have an appointed administrator. I
could be wrong, but it looks like the Russian regions are roughly the
same, except at a higher level.

Wikipedia only lists longest rivers by combined main+tributary, so I had
to compile this list myself. See below for full list.

Mark gets credit for being the only one to name Baffin.

Alpha Centauri
Barnard's Star
Wolf 359
Lalande 21185
Sirius

Didn't really expect anyone to get #4, although Mark knew the name of
the astronomer/catalog that its name comes from. As for Proxima, there
was a paper earlier this year that strongly supported it being part of
the Alpha C system, so I'm going with that. If you include brown dwarfs,
there are two systems that fit in between Barnard's and Wolf 359: Luhman
16 and WISE 0855. I didn't expect anyone to know those, so I excluded them.

>

Sakha Republic (Russia)
Western Australia
Krasnoyarsk Krai (Russia)
Greenland
Nunavut

Erland is the only one to get Sakha. Also see below for full list.

So Mark edges out Dan and Calvin, so it's back to him for RQ #297.
Congratulations, Mark.


Besides the list of rivers, I also had to compile a list of internal
regions. Here are the two lists. I may have missed a river or two, but
I'm fairly certain not among the top five.

Rivers length (km)
====== ===========
Amazon 6992.6
Nile 6853
Yangtze 6357
Huang He 5464
Paraná 4880

Lena 4400
Congo 4370
Missouri 3767
Mississippi 3734
Ob 3650
Volga 3530
Yenisei 3438


Internal subdivisions size (sq km)
===================== ============
Sakha Republic (Russia) 3,103,200
Western Australia 2,645,615
Krasnoyarsk Krai (Russia) 2,339,700
Greenland 2,166,086
Nunavut 2,038,722

Queensland 1,852,642
Alaska 1,717,856
Xinjiang (China) 1,664,897
Amazonas (Brazil) 1,570,745.7
Quebec 1,542,056
Tyumen Oblast (Russia) 1,435,200
Northwest Territories 1,346,106
Pará (Brazil) 1,247,689.5
Tibet 1,228,400
Inner Mongolia 1,183,000
Ontario 1,076,395

These were all that I could find with at least 1,000,000 sq km.

Well, I think I am the closest of the entrants to it.

I commented: "I hope Ellesmere isn't on there -- I think it might be #6."
In fact it's #10 and another Canadian Arctic island, Victoria, is larger
at #9. #6 is Sumatra, which was a wrong answer for me.

I knew it had a 5-digit number too.

Oh, I say! In that case Sirius is a wrong answer and I request a rescoring
with it not accepted.

And so I still do with the rescoring. I don't have one ready to go this
time, but I'll think about it shortly.

If Sakha does not ring a bell: it is also known as Yakutia.

I feel sort of stupid for not spotting Western Australia. At least my
Chinese entries were correct so far that they are actual subdivisions.

I would question Greenland on this list. Greenland is not an "administrative
subdivision" of Denmark, but rather an un-independent country with a high
degree of autonomy. For instance, so far, it is the only area to have
left the European Union. That would make Queensland the next in line, which
some entrants (not me) had.

You certainly did say Baffin. Here's your answer list, which I copied

I explicitly excluded brown dwarfs. Sirius is a correct answer and the
scoring stands.

At the bottom of the quiz, I defined first level administrative
subdivisions thusly:

| Note: First level administrative subdivisions is a collective name for
| subnational units (states, provinces, territories, semi-autonymous
| regions, etc.) that are not part of a larger subnational unit.

Note that it includes semi-autonymous regions. Which is what Greenland
is. So the answer stands.

As for leaving the EU, according to Wikipedia, Algeria left when it
became independent and Saint Barthélemy, a Caribbean island owned by
France, left also. I thought that St-Pierre et Miquelon and French
Guinea also left, but apparently I'm wrong.

I think Mark wants to say that is situated closest to the island of the
contestants. Hey, he even lives in the same country.

Myself, I have flewn over it many times and some times looked down on
the ice and been think "hope we don't have to land here". I did consider it
for a short moment, before I entered Sumatra as my #5.

I don't know about St-Barthélemy, but Algeria was independent decades
before the EU was formed. I've heard that St-Pierre et Miquelon gave
up overseas-department status because of European taxes, but that also
happened before the EU was formed -- perhaps they left the EC.

There is no "French Guinea", but as far as I know the overseas departments
such as French Guiana are part of the EU.

I guess that Dan to simplify equates EU with its predecessors, or simply
sees it as the same thing which have had different names over the years.

The difference between Greenland and Algeria is that Algeria left exactly
because it became independent. Saint Barthélemy is a similar case: according
to Wikipedia, they voted to leave Guadelope in 2003 to become an "overseas
collectivity of France", and I guess this had the consequence that they
are no longer part of the European Union.

Greenland on the other hand, first gained autonomy from Denmark, and then
in 1982 they voted to leave the EEC (as it was called then). This is
different from the Faroe Islands that were autonomous when Denmark
joined the EEC, so they decided to stay out from the beginning.
