172.70.43.53: Lake minimum size variations

I expect that the BTS question is a reference to the traditional Korean system of counting a person's age in units of Sal which started at 1 and incremented on the first day of the year. Since this system was abandoned on official documents in 2023, but is still in use in some contexts, the question of whether every member of BTS had a "birthday" on the first day of the year is ambiguous. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 14:13, 19 April 2024 (UTC)

question 5, planets exist outside the solar system, adding to the ambiguity. [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 14:15, 19 April 2024 (UTC)
:One of the requirements in the definition of a planet is that it orbits the Sun, so no there are no planets outside the Solar system. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 17:50, 19 April 2024 (UTC)

::{{w|NASA}} disagrees. [https://exoplanetarchive.ipac.caltech.edu/ Exoplanet Archive] shows 5612 confirmed planets. -- [[User:Hkmaly|Hkmaly]] ([[User talk:Hkmaly|talk]]) 20:55, 19 April 2024 (UTC)
::: The IAU is the body that defines such things - and they do say that planets have to orbit the Sun...things that orbit other stars are properly called "exo-planets". But still - do we include dwarf planets? Rogue planets? It's definitely a crazy-vague question. [[Special:Contributions/172.70.211.219|172.70.211.219]] 21:05, 19 April 2024 (UTC)
:::: the IAU is one body that claims the authority to define such things, but their authority is not recognized by any of the things they are claiming the right to name. (Except for a very small part of earth, mostly made of humans) [[Special:Contributions/172.69.58.203|172.69.58.203]] 00:10, 20 April 2024 (UTC)
::::That seems ridiculous, "If it isn't one of ours it don't count"? That'd be like saying "They're only 'cars' if they use North American roads, in other countries using THEIR roads you have to call them exo-cars!". LOL! And every future/space-based fiction calls them planets, just makes more sense not to be so arbitrarily exclusionary. Ours isn't the only sun, we shouldn't pretend it has some aspect that makes it count more than others - outside of that it's the one with us. [[User:NiceGuy1|NiceGuy1]] ([[User talk:NiceGuy1|talk]]) 06:09, 20 April 2024 (UTC)

: I think the correct answer is 0: before the solar system formed there were no planets. So, originally, there would have been none. If exo-planets count, going back to the beginning of time gives the same answer: when the universe came into existence during the big bang there were no stars, let alone planets orbiting them. Even religion agrees: in the beginning God created the earth and the heavens, but the sun came later, so technically earth was not a planet since it didn't orbit anything.--[[Special:Contributions/162.158.62.49|162.158.62.49]] 22:23, 19 April 2024 (UTC)

As for question 9, please see the note about the history of Austrailia's capitals at: [[https://en.wikipedia.org/wiki/List_of_former_national_capitals#Oceania]]. and the page regarding countries with multiple capitals [[https://en.wikipedia.org/wiki/List_of_countries_with_multiple_capitals]] [[User:Philhower|Philhower]] ([[User talk:Philhower|talk]]) 14:24, 19 April 2024 (UTC)
: See Also [https://en.wikipedia.org/wiki/List_of_Australian_capital_cities List of Australian capital cities] - As an Australian, I believe many would also consider the major city in their state/territory to be a capital city, although not the capital of Australia.

About the alt text, London is certainly in Europe. The question itself is malformed because "Europe (or 'the EU')" is not self-consistent: there is a lot of European countries that are not part of the EU. [[User:RedGolpe|RedGolpe]] ([[User talk:RedGolpe|talk]]) 14:32, 19 April 2024 (UTC)
:The "Greater London" answer is also tricksy, as the "ceremonial county" of GL {{w|London boroughs|may not include}} the additional area of the City Of London (though it does include the City Of Westminster, which is sometimes the trick answer to certain trick questions that a quizmaster might attempt to pull). The ''administrative'' Greater London is the ceremonial one ''plus'' CoL, however... [[Special:Contributions/172.70.162.19|172.70.162.19]] 15:04, 19 April 2024 (UTC)
::I would argue London is not in Europe because there is no clear definition for Europe as a geographic area, it really doesn't have an eastern border that is not arbitrary, so the only clearly defined thing Europe can refer to is the EU. [[User:Tharkon|Tharkon]] ([[User talk:Tharkon|talk]]) 17:50, 19 April 2024 (UTC)
:::London, France is both in Europe and the EU https://en.wikipedia.org/wiki/London,_France [[Special:Contributions/172.70.163.49|172.70.163.49]] 18:00, 19 April 2024 (UTC)
:::While the eastern border of Europe is not clearly defined I am not aware that there is any definition of (geographic) Europe that excludes the islands (and subsequently London) --[[Special:Contributions/162.158.202.135|162.158.202.135]] 21:24, 19 April 2024 (UTC)
::::There's "mainland Europe", excluding islands. Or at least any of several possibly island archipeligos and/or island nationstates. e.g. Mont-Saint-Michel might not be (exluded, that is, due to being French and having a (tide-dependant) ground access), Jersey would be (British Crown Territory island), Malta probably (island state), Sicily would depend on your thinking (it being Italian, and much larger than the strait that makes it an island offshoot). Most of Scandinavia might be interestingly included (with Denmark) or excluded (with Iceland), according to context. Even Gibraltar might or might not be, depending upon upon the thinking (or lack of it) behind the use of the term. (But, fiddling around the edges aside, (the English) London is not in "mainland Europe" and hasn't been for maybe a full 10kY before it became "London" in any useful sense.)

People, who are born on 29th February don't have a birthday in years which are not leap years. However, 2024, when this comic was published is a leap year. --[[Special:Contributions/162.158.95.9|162.158.95.9]] 14:40, 19 April 2024 (UTC)

"5. How many planets were there originally?" This could also refer even back to the start of the universe, when there were (likely) just 0 planets. --[[Special:Contributions/162.158.86.101|162.158.86.101]] 14:43, 19 April 2024 (UTC)

|-
! Question !! Problem !! Possible answer(s)
|-
| Which member of BTS has a birthday this year?
| Every living person has a birthday this year (being a leap-year, this includes those born on 29/Feb).
|
|-
| How many sides does a platonic solid have?
| There are five (or [[2781: The Six Platonic Solids|six]]) platonic solids, each with a different number of sides.
| 4, 6, 8, 12 or 20
|-
| What is the smallest lake in the world?
| The distinction between a small lake and a pond, pool or puddle (for example) is difficult to define.
|
|-
| Which Steven Spielberg movie features more shark attacks? Jaws (1875) or Lincoln (2012)
| Not a problem, as Lincoln has very few shark attacks.{{Citation needed}} The problem is that barely anyone will ''not'' be able to correctly answer this.
|
|-
| How many planets were there originally?
| Contextually vague. At what time and within what volume of space, and what is the scope of 'planet' defined here?
|
|-
| What NFL player has scored the most points outside of a game?
| Outside of (NFL) games, individuals may accumulate points in any number of ways (e.g. Scrabble)
|
|-
| The Wright brothers built the first airplane. Who built the last one?
| Until no further planes are built, individuals/teams/companies continue to build (to completion) ever more examples, changing the answer possibly moment to moment.
|
|-
| Is every even number greater than 2 the sum of two primes?
| This is a {{w|Goldbach's conjecture|currently unanswered question}}.
|
|-
| Not counting Canberra, what city is the capital of Australia?
| Canberra is ''the'' capital of Australia, a fairly well known 'obscure' fact. Each Australian territory also has their own state capital, so there is not one other ''single'' example.
|
|-
| Who played the drums?
| Lack of context. With which group? For which song? For which (re-)recording? At which event?
|
|-
| Where is London located? (a) The British Isles (b) Great Britain and Northern Ireland (c) The UK (d) Europe (or 'the EU') (e) Greater London
| Almost all of these are correct (though London is geographically in Europe but no longer in the EU).
|}

This is apparently deliberate (at least on behalf of the organisers), perhaps to upset or otherwise impede groups of overconfident quizzers who would otherwise dominate any genuinely good quiz.

...make use of it however you wish, anybody who has the time not to keep chasing all the simultaneous edits.

I thought the answer to #2 could be 1, because as 3D solids they only have one surface. I would guess the player with the most points outside of a game is the one who's played idlers (like Cookie Clicker) the longest — though I suppose those could be considered "inside of a game" as well. Also, I played the drums. [[Special:Contributions/172.70.254.143|172.70.254.143]] 15:33, 19 April 2024 (UTC)

Considering the platonic solids explanation lists all the correct answers, could someone include a list of all the members of BTS and their respective birthdays? Bing copilot suggests the following:

1. **Jin (Kim Seok-jin)**:
- Birthday: **December 4, 1992**

2. **Suga (Min Yoon-gi)**:
- Birthday: **March 9, 1993**

3. **J-Hope (Jung Hoseok)**:
- Birthday: **February 18, 1994**

4. **RM (Kim Nam-joon)**:
- Birthday: **September 12, 1994**

5. **Jimin (Park Ji-min)**:
- Birthday: **October 13, 1995**

6. **V (Kim Tae-Hyung)**:
- V's birthday is **December 30**, but the year is not mentioned in the provided information.

7. **Jungkook (Jeon Jungkook)**:
- Jungkook's birthday is **September 1**, but the year is not mentioned in the provided information.

London is both a City (London) and a City within a City (The City of London) and an Area (Greater London)
There are also many more places named London than the one that is the Capital of the UK .. Serbia, France, Canada (Which is larger and the one in the UK), 10 in the USA, and one on Kiribati 17:56, 19 April 2024 (UTC)
:Are you saying London, Ontario, Canada is BIGGER than the more famous London, England??? That's a country capital! Is that seriously true? I'm Canadian, I don't know London, ON as being THAT big... [[User:NiceGuy1|NiceGuy1]] ([[7User talk:NiceGuy1|talk]]) 05:52, 20 April 2024 (UTC)
::It's very unlikely to be larger in population terms than the (common!) wider definition of the main UK London, as that would make it larger than any other city in Canada by a large margin. In terms of area, London ON is very likely to be larger than the City of London (which is surprisingly small). More widely, the definition of what actually is a "city" is more complex than it appears to be at first glance; administrative areas (what official statistics are collected for) are often quite different from where the bulk of people are. --[[Special:Contributions/162.158.74.25|162.158.74.25]] 07:20, 20 April 2024 (UTC)

The only correct answer(s) to "who played the drums" would be "the drummer", or "twelve drummers", but I would accept Phil Collins, Alex Van Halen, or Ringo Starr for half a point each [[Special:Contributions/108.162.241.100|108.162.241.100]] 02:40, 20 April 2024 (UTC)

I came here all prepared to say that the Title Text should have Ontario, Canada as a (likewise correct) answer, but I see somebody already put that into the table, LOL! I feel like the "More Reasonable" version of the planet question should NOT mention Pluto, it should be the question IMPLIED in the comic whose answer is 9 (such as "How many planets were originally in our Solar System", but without the ambiguity of "originally". Basically a question whose answer is 9, pushing people to include Pluto, while allowing people the mistake of saying the current answer of 8, but mentioning Pluto would ruin that/the question).

I thought I knew the minimum size of a lake by definition, at least in the US, but I just found different authorities asserting 1, 10, and 20 acres as the distinction between a lake and a pond. Two non-metric distinctions are that a lake has an aphotic (dark) zone, or a lake is fed and drained by a river, but they don't help here.

The {{w|periodic table}} is used to arrange {{w|chemical element}}s based on their properties. This comic groups them together into regions.

=== Table Sections ===

{| class=wikitable
! scope="col" | Section
! scope="col" | Real table
! scope="col" | Elements contained
! scope="col" | Explanation
|-
| Slightly fancy protons || Hydrogen || Hydrogen || Hydrogen atoms are a proton and an electron. Since the electron can be removed and you can call that a Hydrogen+ ion, hydrogen is a slightly fancy proton.
|-
| Weird dirt || Group 1 and 2 metals || Lithium, Beryllium || Lithium and beryllium, as some of the lightest elements, have unusual properties compared to heavier metals. Lithium, for instance, is the least dense metal on the periodic table, and beryllium is both toxic and transparent to x-rays.
|-
| Regular dirt || Group 1 and 2 metals || Sodium, Magnesium, Potassium, Calcium || Despite being metals, these are listed as "dirt" rather than "metal." Perhaps this is because they are commonly found in dirt, as they are essential nutrients for plant life (and all other life forms).
|-
| Ends in a number, let it slumber. Ends in a letter, not much better. || Group 1 and 2 metals || Rubidium, Strontium, Cesium, Barium, Francium, Radium || Highly reactive metals, some of which are commonly used as radioactive isotopes (which are known by a number).
|-
| Boring alloy metals. Probably crucial to the spark plug industry or something. (But one of them is radioactive so stay on your toes.) || The left transition metals || Scandium, Vanadium, Chromium, Manganese, Yttrium, Zirconium, Niobium, Molybdeneum, Technetium, Ruthenium, Hafnium, Tantalum, Tungsten, Rhenium || Not actually so boring, but they tend to be used as consituents (sometimes as a small but vital trace) in alloys with specific uses, including {{w|stainless steel}}, {{w|Electric light|bulb filaments}} and {{w|Superconductivity|superconductors}}.<br/>A {{w|spark plug}} may use {{w|austenitic stainless steel}}, which includes chromium and (in some cases) molybdenum, for heat and oxidation resistance.<br/>{{w|Technetium}} is the lightest element that has no stable isotope.
|-
| Regular metals || The top transition metals || Titanium, Manganese, Iron, Cobalt, Nickel, Copper, Zinc, Aluminum, Silicon || Commonly known metals (and one metalloid, silicon). These all have important uses in construction and other major industries.
|-
| $$$ || The platinum group || Rhodium, Palladium, Silver, Iridium, Platinum, Gold || Rare and highly prized metals.
|-
| Weird metals || The "ordinary metals" and some transition metals || Gallium, Germanium, Cadmium, Indium, Tin, Mercury || These are more obscure than the other metals (except tin and mercury) and tend to have fewer or more specialized uses. Mercury is also the only metal that is liquid at room temperature, and gallium melts just above that at 30 °C (86 °F).
|-
| Boron (fool's carbon) || Boron || Boron || A search for "carbon" in {{w|boron}} finds mention of a number of similarities between the two elements. "Fool's carbon" is analogous to {{w|Pyrite|"fool's gold"}}.
|-
| You are here || Nonmetals || Carbon, Nitrogen, Oxygen, Phosphorus || Elements involved in biological processes
|-
| Murder weapons || Ordinary metals and metalloids || Arsenic, Antimony, Tellurium, Thallium, Lead, Bismuth, Polonium || Arsenic, thallium, lead, and polonium are highly toxic and have been involved in many notorious poisoning cases. Antimony and tellurium are also hazardous, though to a lesser degree. Bismuth is the odd one out, having little toxicity at all, but it is used in lead free bullets and shot; the compound bismuth subsalicylate is the main ingredient in Pepto-Bismol.
|-
| Safety Goggles required || The halogens || Fluorine, Sulfur, Chlorine, Selenium, Bromine || These elements are highly reactive.
|-
| Very specific health problems || Iodine and radon || Iodine, Radon || Radon can accumulate in buildings, especially in basements and cellars, since it is a gas that is denser than air. Since it is also radioactive, this accumulation can then result in radiation sickness. Iodine is a required nutrient that humans need in trace amounts to remain healthy, with an iodine deficiency typically causing thyroid problems such as goitre. These two specific health problems are entirely unrelated and it is only by coincidence that they are next to each other on the periodic table.
|-
| Lawful Neutral || Noble Gases || Helium, Neon, Argon, Krypton, Xenon || These elements are mostly unreactive. Lawful Neutral is a reference to the D&D alignment chart, which gives moral categories for characters. The chart goes from Lawful to Chaotic on one axis, and Good to Evil on another. Lawful Neutral means following the law without any bias towards Good or Evil, which could be exemplified by the unreactivity of the Noble Gases.
|-
| Don't bother learning their names – they're not staying long || Astatine and Period 7 from Rutherfordium onwards || Astatine, Rutherfordium, Dubnium, Seaborgium, Bohrium, Hassium, Meitnerium, Darmstadtium, Roentgenium, Copernicum, Nihonium, Flevorium, Moscovium, Livermorium, Tennessine, Oganesson || These elements are hard to produce in large quantities and most of them decay within hours.
|-
| Whoever figures out a better way to fit these up there gets the next Nobel Prize || The internal transition metals || Lanthanum, Cerium, Praesodymium, Neodymium, Promethium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Lutetium, Actinium, Thorium, Protactinium, Uranium, Neptunium, Plutonium, Americium, Curium, Berkelium, Californium, Einsteinium, Fermium || The lanthanides and actinides are placed kinda awkwardly "outside" of the main periodic table; alternative ways of displaying the elements, such as just putting them between the alkali earth elements and the transition metals, are usually considered visually less appealing.
