Subject: Basic question about blocks

Hello forum,

I am new to Ruby and have a question about blocks.

A) Below is the code I have put in a file <blocksexample.rb>:

---------------------------------------------------
# Script block2.rb
def simpleFunction
      yield
      yield
end

animals { |x| puts "Hello, #{x}" }
animals { |x| puts "It's #{x.length} characters long!" }
---------------------------------------------------

B) I run the <blocksexample.rb> as below....only once:
---------------------------------------------------
C:\RUBYEX~1>blocksexample.rb
---------------------------------------------------

C) The output is as below:
---------------------------------------------------
Hello, Tiger
Hello, Giraffe
It's 5 characters long!
It's 7 characters long!
---------------------------------------------------

Question 1: How is it I am not getting error for using same name
<animals> for 2 blocks in the same <rb> file?
Question 2: How is the first animal block executed followed by the
second animal block execution...inspite of me running the example only
once...

Please let me know, appreciate your help in advance.
