# Geography (2)

On June 15, I published an 8 question test with alternate geography questions. Here is a short bonus. As in the previous test, the questions are replicated for several continents
After writing it, I discovered “World Geography” in the Android play store. It featured a series of different question types, some traditional, others less common, such as:
a) With a map of the continent shown, and one country highlighted, what is the name of this country?
b) With just the silhouette of the country shown, what is the name of this country?
c) What is the capital of a country?
d) Of which country is this the flag? (flag depicted)
e) how many inhabitants does a country have (<1 million, <10 million, <100 million, >100 million)

Here are some questions. Unlike my previous quiz, the questions are not by continent, but are worldwide.

1) Which islands are depicted?

2) Name the countries which belong to these flags:

3) Rank these cities from North to South:
Beijing, Berlin, Moscow, and Washington

4) Rank the following countries according to number of inhabitants:
Canada – Bangla Desh – France – Egypt

5) Rank the cities from least to most annual rainfall
Los Angelos – Washington – Madrid – Cairo – Tokyo

6) In which countries do these rivers have their origin?
Amazon – Nile – Donau – Mekong

I would like to thank user Rei-artur of wikimedia commons for releasing the first of the island maps above.

I have posted a small series of truth or lie puzzles at this blog, you can find them here.

This week I have just a link for you. Russian born USA mathematician published a nice puzzle here. It’s a toughy.

# Rikudo

Rikudo**/***** essentially are made up of a (partially hidden) string of the numbers 1 to N embedded in a figure consisting of hexagons.
I must admit I never figured out how to efficiently draw a couple of hexagons, so I’ll use squares arranged alternating in adjacent rows – the net result is identical in terms of the number of adjacent borders.
Usually, the number 1 and the highest number are given. Sometimes the author puts a dot on a border to indicate that the adjacent numbers differ by 1.

Solving strategies

1. A straight line between two given numbers, with the length of the line equal to the difference between the two numbers

2. Two adjacent hexagons have numbers which differ by two

3. No dead ends

Though there are several routes from 6 to 10, only 1 will fill the red square.
