Quizzes & Puzzles 11 *Some new problems with which to exercise the brain. But first a look at answers and solutions to* *Quizzes & Puzzles 10**. New problems below the image (cartoon).* https://read.cash/@Mictorrani/quizzes-puzzles-10-82143868 Answer to Quiz 10:1 “*Which vitamin can, if the conditions are right, be produced by sunlight on the skin and absorbed that way?”* The answer is vitamin D. If you want to learn more details about vitamin D, I suggest you read my article Vitamin D – Underrated Vitamin? https://read.cash/@Mictorrani/vitamin-d-underrated-vitamin-5ca83053 Answer to Quiz 10:2 “*One mammal uses echo-location in order to navigate in its environment and to find food. Which mammal?”* Of course, this is the bat.

In the preface of “Selection No. 2 from Transformations of a Bat”, en e-book I published in 2012, I wrote: “*[...] In terms of ability to manoeuvre it [the bat] is the best flier of the fauna. Considering that it is almost blind and can hunt, follow, and catch flying insects by echo location, it is impossible not to be impressed by its perfect adaption to being an insect eater as well as a night-living creature.* *Some bats eat fruit. While navigating through the branches of fruit trees by echo sound is not as hard as following a flying insect, it is still an amazing feat. One species drinks blood, and that, naturally, is why people have come to associate bats with vampires.* *It would be interesting to know how the brain of a bat represents the result of this echo location, whose nervous impulses must be reflex-bound to be able to direct the muscular system and thus its manoeuvres in fractions of a second. Is there any conscious registration of this at all? Do bats even have a consciousness in any sense of the term? We will never find answers to such questions, confined as we are within our own consciousness. [...]”* Answer to Quiz 10:3 “*Which country share its borderline with all other countries on its continent – except two?”* The right answer is Brazil, which borders to all countries on the South American continent, except for Chile and Ecuador. Answer to Problem 10:4 “*When Carl was one year younger than John was when Henry was half as old as John will be 3 years from now, Henry was twice as old as John was when Henry was 1/3 as old as Carl was 3 years ago. But when John was twice as old as Carl, Henry was 1/4 as old as John was one year ago. Carl is over 50.* *How old are Carl, John and Henry?”* Carl is 72, John is 85, Henry is 80. *Aimure* *and* *Esp130* *gave right answers to quiz 1-3. But before that,* TheGuy correctly answered quiz 1-2. https://read.cash/@Aimure https://read.cash/@Esp130 https://read.cash/@TheGuy

*And now some new exercises for brain & memory... This time we take only quizzes, but a few more than usually.* Quiz 11:1 Countries sometimes change name. Although it doesn't have to be so, this is often done to mark some fundamental change in the country's status or a major change of its policy. Below you find seven old names; what are the names of these countries today? a. Upper Volta b. New Hebrides c. Siam d. Persia e. Burma f. Ellice Islands g. Rhodesia Quiz 11:2 Which ruler ruled the largest connected empire in human history? "Connected" here means one single connected territory - not pieces of land spread out with sea or other countries in between. Quiz 11:3 Which Japanese artist is often, rightly or wrongly, said to be the one who originally created manga?

Quiz 11:4 Bitcoin was the first cryptocurrency, but which was the first altcoin? Quiz 11:5 What are we talking about when we call colours "tinctures"?
