question 2
a =10
(a < 100) && true && (puts "Made it here!")

my answer: (no output)
correct answer: "Made it here!"
answer according to irb: "Made it here" with =>nil right below it.

i'm confused. what's the difference between =>nil and (no output)?

question 3
a=10
(a>=0) || (puts "Greater than or equal to")

my answer: true
correct answer: (no output)
answer according to irb: true

what's going on here?

Your quiz is asking you for the OUTPUT of the code snippet.
What IRB gives you is the output AND the return value.

In IRB if you type puts "Hello World" the output will be "Hello World"
but the return value will be nil.
If you type 1 + 2 there will be no output (because you don't have a
puts statement) but IRB will show you the return value which is 3.
