Houston is #4 (after the same top three) if only the *city proper* population is considered. It didn't occur to me to check that before, because of course city limits are irrevelant to TV markets. Anyway, now we know. -- Mark Brader, Toronto | "The brain is amazing when it's amazing, with msb@vex.net | apologies to Robert Biddle." --Steve Summit My text in this article is in the public domain. |
| swp <stephen.w.perry@gmail.com>: Nov 04 09:25AM -0700 this is rotating quiz #273. today is november 4th, 2017. the winner will be the first choice to set rq 274, in a manner of their choosing. please answer based only on your own knowledge; put all of your answers in a single posting, quoting the question before each one. answer slates must be posted before 9pm edt (philadelphia/toronto time) on saturday, 2017-11-11, which gives all of you a lot of time from the time of this posting. in case of a tie, the first tiebreaker will be who scored on the hardest questions; and the second tiebreaker will be who posted first. correct answers are worth 1 point each. have fun! a. what is the only elemental metal that does not rust? b. what is is the only muscle in your body that is attached at only one end? c. what is the only number that cannot be represented using roman numerals? d. rounded to the nearest 10%, what percentage of all living things live in the ocean? e. why do Airports at higher altitudes require a longer airstrip? f. what are the only fruits whose seeds grow on the outside? g. what has he highest calories of any fruit at 167 calories per hundred grams? h. how far away from the earth does the moon move every year? i. how much heavier does the earth get each year due to falling space dust? j. what is the largest river flowing into the adriatic sea? good luck! swp |

Most metals are subject to oxidation, but some, like aluminum acquires sheltering layer of oxde which prevents further oxidation. I guess you mean the only metal that do not form an oxide with the oxygen in air. Again, I would exoect that to be more than one, but I may be wrong on that point. I go with gold. > b. what is is the only muscle in your body that is attached at only one > end? tongue > c. what is the only number that cannot be represented using roman numerals? zero. > d. rounded to the nearest 10%, what percentage of all living things live > in the ocean? 90. > e. why do Airports at higher altitudes require a longer airstrip?

| msb@vex.net (Mark Brader): Nov 04 03:40PM -0500 Stephen Perry: > a. what is the only elemental metal that does not rust? Well, I'd say "rust" means "form iron oxide", so that would be all of them except iron. I'll go with gold, though. > b. what is is the only muscle in your body that is attached at only one end? I'll go with the tongue. > c. what is the only number that cannot be represented using roman numerals? Depending on what you mean by "number" and "represented", and for that matter "Roman numerals", there could be lots and lots. I'll go with 0. > d. rounded to the nearest 10%, what percentage of all living things live > in the ocean? I have to think soil provides a better home for microorganisms than anything in the ocean, so I'll guess as low as 40%. > e. why do Airports at higher altitudes require a longer airstrip? Ah, an easy and reasonably well-defined question. The amount of lift available at a given airspeed is reduced because the air is less dense, so more distance is needed to reach a higher takeoff speed (and to slow down from a higher landing speed). > f. what are the only fruits whose seeds grow on the outside? Strawberry? > g. what has he highest calories of any fruit at 167 calories per hundred grams? Strawberry? It was a good guess the first time. > h. how far away from the earth does the moon move every year? Wow, that's obscure. Well, it can't have receded by more than the present radius of its orbit since it formed originally, so for an order of magnitude say 400,000 km in 4,000,000,000 years... then no more than about 1 km per 10,000 years or 10 cm per year. But the rate of recession will certainly have descreased over that time and I don't know what orbital radius it would have formed at in the first place. I'll say 5 mm per year. > i. how much heavier does the earth get each year due to falling space dust? Wow, that's even more obscure -- I can't think of any way to get a handle on it I'll just guess 1,000 metric tons. > j. what is the largest river flowing into the adriatic sea?
