Which country was the protectorate ??

 This question was asked on Koun Banega Karodpati program.

Question 

Which country besides  France had a protectorate in Morocco ??

1.  Switzerland 

2.  Russia 

3.  Denmark 

4.  Spain

Answer 

Before answering this question, we will understand what is protectorate  ??!!

Protectorate is a state or territory that is under the  protection and control of a more powerful country.

In this case, powerful country is Britain.

Protectorate was Spain   !!!

Protecting power mainly handles defense and foreign affairs.

Protectorate manages internal affairs.

Britain was most powerful naval force at that time and was deeply concerned about control of strait of Gibraltar.

They did not want  France to control Moroccan coast. Spain was seen as a " weaker power " that would not pose a threat to Britain.

So, answer      SPAIN       !!!!

Bheja Fry question

  This Bheja Fry question I came across when searching Internet.

Question 

If        1111  =  R

          2222   =   T

          3333     =   E

Then       4444    =   ???

Answer 

  

I didn't know the answer  !!!

Some reader used his brain and solved the puzzle.

After looking at solution, I thought it was easy.

Let's have a look at    1111.

When we add all the digits, 

            1 + 1  +  1  +  1   =  4  =  fou  '  R  '

Now   2  +  2  +  2  +  2  =  8 =  eigh    '  T   '

Now  3 + 3 + 3  +  3  =  12  =   twelv   '   E   '

Finally,    4  +  4  +  4  +  4  =   sixtee      '   N   '    !!!!!

Why animals in cold climates are comparatively bigger ??

  We must have noticed animals found in polar regions are comparatively larger to their southern counterparts.

There is a scientific reason for this.

It is BERGMANN'S RULE 

It States that " warm blooded animals in colder climate tend to be larger than those in warmer climates "  

It is the simple allometric relationship between body size and surface area.

Larger animals have proportionately smaller surface area compared to smaller amimals.

Because all warm blooded animals lose their internal heat generated by their metabolism to their environment through their body surface.

Larger bodied animals lose their heat at a lower rate compared to smaller body animals .......

Hence, animals in colder regions have larger body so that they can conserve energy for a long time   !!!!
